With the accelerating of globalization and regional economic development, industrial isomorphism as a practical problem on spatial division attracts the widespread concerns of academic communities. Ordinarily, industrial isomorphism is considered harmful to the process of regional integration. A regional division which has complementary advantages will do help to format economic agglomeration and coordinate regional development. In order to reflect the regional industrial division status more accurately, this paper used a comprehensive method which combined the Variation Coefficient with the Lorenz Curve and Geordie coefficient to quantitatively study the industrial division status of Liaoning coastal economic belt at the product level and proposed the suggestions of coordinated development. The results show that: (1) in the agriculture and excavating industry, all regions develop the competitive industries according to their comparative advantages, and the industrial division is relatively clear; (2) in manufacturing, the structures are similar on the industry level, but on the product level, all regions develop differently and industrial division is emerging; (3) the internal structure of the tertiary industry needs to be adjusted, basic services and personal consumer services develop more perfectly, and some parts of production and market services and public services lag behind, especially finance, logistics, professional technical services and public management services which affect the process of industrialization promoting and the industrial structure upgrading. And finally we propose the coordinated development suggestions according to the industrial division results: the agriculture and excavating industry should expand industrial scale, promote characteristic development and improve product added-value; in manufacturing, industrial division is gradually appearing, and the future development should focus on the competitive industrial clusters, including transport equipment, general equipment manufacturing and petrochemical industry and metallurgy industry clusters; the internal structure of the tertiary industry should be adjusted, the logistic industry and the financial industry should be enhanced and a modern logistic network and financial service system should be built. The public management services should also be developed so as to optimize the regional allocation of resources, innovate management system and promote regional sustainable development.

With the growing popularity of marine issues, some scholars are concerned about the marine carrying capacity closely. An assessment of marine ecological carrying capacity can provide an overall impacts resulting from the marine ecological construction. Therefore research on the theories and methods of the marine carrying capacity are significant for the regional sustainable development. This paper introduces the model of ecosystem health to establish the general measuring indicators for Liaoning marine ecological carrying capacity and conducts a decade-long research on Liaoning marine system. The concept of the marine ecological carrying capacity based on ecosystem health is investigated to overcome the shortcomings of the traditional studies that are not convenient to use in practice due to their relatively simple assessment standards and conclusions. A corresponding conceptual model and computation model of the marine ecological carrying capacity are further proposed to analyze impacts of the marine ecological construction. In addition, the established methods of index system and the assessing standards for the marine ecological carrying capacity assessment are proposed. For example, the marine ecological carrying capacity of Liaoning Province is studied. An index system, weights and corresponding appraisal standards for the marine ecological carrying capacity are established for analyzing the marine ecological carrying capacity deeply between 2000 and 2010 in this area. The results demonstrate that marine ecological carrying capacity index rises up, its index rose from 0.0724 in 2000 to 0.2184 in 2010, and the state of ecosystem increased from un-health level to sub-health level. The resource and environment carrying capacity remains sub-health level for a long time. Its index rose from 0.0432 in 2000 to 0.1670 in 2010. The ecological resilience index rose from 0.0510 in 2010 to 0.1249 in 2010, and the state of ecosystem increased from un-health level to sub-health level and reached the health level in 2010. The potential human activities remain un-health level and this situation takes a turn for the better in almost two years. Its index is continuous declining between 2002 and 2006, their state of health level before 2009 had been in the unhealthy state, only in 2009 and 2010 it was in the sub-health state. For the sustainable marine economy, many more efforts should be made in terms of marine industrial structure adjustment, pollution control and marine technology. In future, we must strengthen the marine ecological carrying capacity index optimization to improve the level of ecological carrying capacity and health level and realize the sustainable development of marine economy. This research put forward method for measuring the ecosystem health related marine ecological carrying capacity in view of the fact that some data are not available, the selection of indicators is not so comprehensive, but this paper helps broaden the field of vision and makes human activities greatly reflected in marine ecological carrying capacity.

Water shortage has become a bottleneck to restrict the sustainable development of China's economy, especially in the Liaoning Coastal Economic Belt (LCEB). So the research on marginal effect of water resources is important and necessary for the sustainable development of LCEB. The theory of marginal effect is the cornerstone of this paper. To quantitatively analyze the impact of water resources on the regional output value based the three industries, the paper took water resource as the factors of production. And, in this study, the Cobb-Douglas function was employed in the computation of marginal revenues of water in LCEB over the period of 2002-2011. The results indicated that, in 2002-2011, the marginal effect of three industries increased year after year, and the marginal effects of agriculture, industry and the tertiary industry water was 4.11, 82.30 and 154.93 yuan/m³ respectively. The marginal effect of agriculture water was significantly less than that of industry and the tertiary industry water. Due to the different nature of the three industries, their influence factors are abundant and varied. To investigate the key factors of marginal effect for water resources, multiple linear regression model was built based on the results. Our model showed that the influence factors exactly revealed the impact of marginal effect of water resources, and the factors had both positive and negative effects. The results showed that: the factors that affected agricultural water were the water consumption of agricultural output value per ten thousand yuan, the influence of government, the yield per unit area, and the amount of fertilizer consumption; the factors affected marginal effect of industry were the water consumption of industrial output value per ten thousand yuan, the amount of industrial wastewater emission, the influence of government, and the degree of market demand; the factors affect marginal effect of the tertiary industrial water were the water consumption of the tertiary industry output value per ten thousand yuan, the level of urbanization, the influence of government, and park green area per capita.

The coordinated development between economy and environment is key to keep the sound development of regional integrated system.Economic and environmental coordination development degree is one of the important quantitative indicators for measuring capacity for sustainable development in a region.Based on drawing lessons from the existing research results and the research methods, this article constructs an evaluation index system of economic and environmental coordination development degree in Liaoning coastal economic belt consisting of six cities, and uses the model of coordination development degree for calculation and spatiotemporal evolution analysis of coordination development degree in the study area.Results are shown as follows.In the temporal evolution, the trend presents a "V"-shaped pattern in regional comprehensive coordination degree, with a steady rise in this belt.Development level of the six cities is higher, reaching the intermediate level.In the spatial evolution, the six cities can be divided into three types, and the eastern and southern cities are more harmonious than the western and northern ones, but the gap between their urban spaces is gradually narrowing.In addition, from these aspects of the macro-regulation, the upgrading of the industrial structure, regional layout optimization and the improvement of environmental protection threshold, the paper analyzes the reason for the spatiotemporal evolution of economic and environmental coordination development degree in Liaoning coastal economic belt, and pointed out that, driven by the above factors, economic comprehensive development levels and environmental strength have increased.And due to the industrial isomorphism and fragile coastal ecology, changing the mode of economic growth and promoting the harmonious development of regional economy and environment are still the main tasks in the future.

辽宁省是东北唯一的沿海省份, 而海洋环境是经济增长的重要影响因素和承载, 因此研究辽宁沿海经济带经济与海洋环境协调发展是实现辽宁经济可持续发展的关键。本文在对辽宁沿海经济带经济和海洋环境现状分析的基础上, 从经济、海洋环境两个方面科学合理选取评价指标, 采用可变模糊识别模型研究经济带经济与海洋环境的协调性。结果表明:辽宁沿海经济带各地区的经济增长与海洋环境发展尚处于略好于动态平衡却远不足于明显协调阶段。从时间序列上分析, 辽宁沿海经济带战略并非对各区均有利且弊端明显, 以2008年较2005年为例, 虽然盘锦、丹东、葫芦岛和锦州地区协调度呈上升趋势, 而营口和大连地区协调度却呈下降的趋势。并且通过产业分解和GK.E模型深入剖析了辽宁沿海经济带的经济发展差距和海洋环境污染节距, 产业分解显示一产、二产和三产分别对经济差距起到了减缓、加剧和维系的作用;而GK.E模型分析, 在经济结构和集中效应影响下, 盘锦和丹东葫芦岛地区的海洋环境要明显好于大连、锦州和营口地区。

Liaoning Province is the only coastal north-east province of China, while the marine environment is an important influencing factor and bearing of economic growth, so the study of economic coordination with economic development and the marine environment is the key to achieve Liaoning sustainable economic development. In this paper, Liaoning coastal economic belt and the marine environment of economic analysis, based on economic, select both the marine environment evaluation, built in Liaoning coastal economic belt and the marine environment, sustainable development, economic evaluation index system, evaluation of class division, and using AHP method to determine the index weight, while the use of variable fuzzy recognition model analysis of Liaoning coastal economic belt and the marine environment of economic coordination degree.The results show that: the regions of Liaoning coastal economic belt’s economic growth and development and the marine environment are still in a condition that a little better than the dynamic equilibrium but far less than in the apparent coordination stage. From the time series analysis, Liaoning coastal economic zone strategy is not beneficial but drawbacks of various apparent to the regions. For example, to contrast 2008 and 2005, although the coordination degree of Panjin, Dandong, Jinzhou are rising, Huludao,Yingkou and Dalian are in a downward trend. And by industry decomposition and GK.E model analysis the gap of the regions of Liaoning coastal economic belt and the marine environment pollution disparity, industrial production shows that primary, secondary and tertiary industry were played on slow down economic disparities, increase and maintain the effect; and GK.E model analysis, under the effect of economic structure and concentration, the marine environment in Panjin, Dandong area was significantly better in Dalian and Yingkou.

This paper builds the evaluation indicator system for water use efficiency and coordinated development of economy coupling in Liaoning coastal economic belt (LCEB). Firstly, using improved mutation model to evaluate status of LCEB water use efficiency and the economic development of each subsystem from 2001 to 2010. Secondly, using coupling coordination model to evaluate water use efficiency and the coupling coordination degree of economic development of every city of LCEB. The results show that the coupling degree of water use efficiency and the economic development of LCEB increased from 0.437 to 0.498, which is slowly improving, but it has been in the stage of resisting. The gap of water use efficiency and economic development level decreases continuously, and the coupling coordination degree increased from 0.254 to 0.408, which showed a trend of increase but still at the mid-low level of coordination. Water use efficiency and economic growth of every city of LCEB are in a rising trend, water use efficiency of Dalian is the best with an evaluation value reaching 0.887, Jinzhou, Yingkou and Huludao are in the second place, Dandong and Panjin at the worst level with evaluation values being 0.604 and 0.535. The economic development level of Dalian is the highest, Yingkou and Panjin are at intermediate level, Dandong, Jinzhou and Huludao are at the lowest level. The coupling degree of every city in the stage of resisting, and in a rising trend. The coupling coordination degree of Dalian and Yingkou have reached 0.457 and 0.401, and entered the stage of moderate coordination from low-grade coordination phase,and showed a rising trend. The coupling coordination degree of Dandong, Jinzhou, Panjin and Huludao still at the low level of coordination and showed a fluctuated increase.The economic development of every city falls behind the improvement of the efficiency in water usage, which causes the coupling coordination being in the mid-low grade period. The regional disparities among the coupling degree and coordination degree of LCEB are decreasing, and the coordinated development trend of economic belt becomes more and more apparent.

Water resources are the key factor to the development of society, economic growth, the improvement of living standard of people, and the improvement of the environment. The shortage of water resources has become one of the important factors hampering the sustainable development of social economy in Liaoning coastal economic belt, which is one of areas falling severely short of water resources in the region. The contradictions between water supply and demand are becoming increasingly significant. In addition, the study would be beneficial in the formulation of strategy for the old industrial base in northeastern China. In this paper, the current situations of sustainable development of water resources and social economy in Liaoning coastal economic belt were analyzed. Based on special conditions of water resources and social and economy in Liaoning coastal economic belt, an assessment index system involving 24 indices for sustainable development of water resources and social economy was established. These indicators depict three major aspects including water resources, society, and economy. The assessment index grades were calculated. The Analytic Hierarchy Process (AHP) method was used to determine the weight of each assessment index. Data of cities in Liaoning coastal economic belt were used. As a result of the complexity and uncertainty of the water resources system, the variable fuzzy recognition model was chosen to evaluate the assessment index system quantitatively for each layer. The average value of the past four years was taken as the current situation of sustainable development of water resources and social economy in Liaoning coastal economic belt. Results show that the levels of the sustainable development of water resources, society, and economy for Dandong and Dalian were slightly higher than the moderate level. Those of Huludao, Yingkou, and Jinzhou were low to intermediate. Panjin lay in a low grade. The whole study area exhibited a low to an intermediate level. The evaluating results seem to be reasonable.

Urban agglomerations are the main carrier of regional economic and green development in China, and their strategic position is rapidly increasing. Under the targets of carbon neutralization and carbon peaking, research on coordinated governance of urban agglomeration pollution control and carbon emission reduction is an important content of exploring regional sustainable development. Based on the mechanism of change of coordinated governance of pollution control and carbon emission reduction, this study used the panel data of the three major urban agglomerations of China from 2010 to 2019 to measure the coordination degree of coordinated governance of pollution control and carbon emission reduction in these regions with correlation coefficient matrix method and composite system coordination degree model. Using Gini coefficient, coefficient of variation, Theil index and its decomposition method, and gravity model, this study analyzed the regional differences and spatial connection intensity of the coordinated governance of pollution control and carbon emission reduction and identified the critical pathways of pollution control and carbon emission reduction coordinated governance. The results show that: (1) The orderliness degree of coordinated governance in the three major urban agglomerations showed a significant growth trend; However, the coordination degree is low, and the system is in an unstable and uncoordinated state. (2) The differences in the coordination degree of coordinated governance of pollution control and carbon emission reduction in the Beijing-Tianjin-Hebei region gradually decreased, while the differences in the Yangtze River Delta remained stable, and the internal differences in the Pearl River Delta fluctuate greatly. (3) The network density and network structure complexity in the Beijing-Tianjin-Hebei region and the Pearl River Delta are higher than those in the Yangtze River Delta, and the spatial connection intensity is higher. The cities are interconnected and influenced by each other. The coordinated governance of pollution control and carbon emission reduction in the three major urban agglomerations can be promoted from the aspects of policy, technology, capacity building, top-level design, transformation and upgrading, and cooperation and expansion.

Scientific zoning of urban economic linkage structure is essential for improving and optimizing the functional layout of metropolitan areas, as well as for guiding integrated economic development. Based on the relative gravity vector introduced in this article, the conventional gravity model had been improved and applied in the Wuhan Metropolitan Area for exploring the economic linkage structure and gravity zoning. The results show that: the improved gravity model can indicate the actual conditions of unsymmetrical relative gravity between two cities. It shows three types of economic linkage structure, including driving, dependent, and complex structures in the Wuhan Metropolitan Area, and Wuhan was the single city that showed strong driving economic power in relation to other cities in the area. According to the gravitational attraction that represents economic linkage structure, cities in the area were divided into three zones, namely the "Xiaogan-Wuhan-Xianning", "Huangshi-Ezhou-Huanggang", and "Xiantao-Tianmen-Qianjiang"urban cooperation groups, with the former as the "center" and two latter groups form the "wings".

High-quality development is the key measure to overcome the middle-income trap and join the advanced economy. With the deepening of reform and opening up, coastal areas have increasingly become the ballast of the economic growth, the center of national manufacturing, the frontier zone for building an innovative country, the pacesetter for constructing an open economy, and the demonstration window for green development. With typical characteristics of high-quality development, coastal areas will effectively drive the hinterland areas to the right track of high-quality development in order to form a strong support for the country's high-quality development, shaping a new pattern of coordinated regional development. According to the status quo and characteristics of high-quality development in coastal areas, this paper focuses on exploring outstanding problems of coastal areas as a whole and the northern, central and southern coastal areas in the process of high-quality development from five aspects of economic growth, industrial strength, innovation ability, opening up and green development. By analyzing realistic reasons for these problems, valuable references for the design of targeted high-quality development paths are designed. In the new era, coastal areas should grasp the historical opportunity of Beijing-Tianjin-Hebei coordinated development, Yangtze river delta integration, Guangdong-Hong Kong-Macao Greater Bay Area construction, follow to improve industry core competitiveness, mobilize the vitality of innovation, build high-standard open economy, deepen ecological conservation by combining strategies of industrial upgrading, independent innovation, opening up and ecological civilization. By the method of working in concert to promote high-quality development in the northern, central and southern coastal areas, the leading role of coastal areas can be consolidated.

推动黄河流域高质量发展,有必要构建黄河流域高质量发展评价指标体系以对黄河流域高质量发展水平进行科学测度。本文从经济社会发展和生态安全两大方面,包含经济发展、创新驱动、民生改善、环境状况和生态状况5个维度,构建了黄河流域高质量发展评价指标体系,并基于黄河流域9省区2008—2017年的数据,运用熵权法进行了测度。结果表明：黄河流域高质量发展水平基本呈现“两边高、中间低”的空间分布,但差距逐年变小;各省区高质量发展水平在2008—2010年基本保持平稳,2011—2017年持续增长,且在2016年增速明显;黄河流域整体高质量发展水平呈现上升趋势,在2008—2010年小幅波动,2011年起上升明显;10年间5个维度均有不同程度的改善。据此,本文对提升黄河流域高质量发展水平给出了具体建议：①借助政策红利叠加效应,进一步加强区域联动,扩大黄河流域整体对外开放水平。②西部各省区在重点保护生态环境的基础上,结合要素禀赋,发展特色产业。③山东省和河南省在发展经济的同时,要加大对生态环境的保护力度;山西省和甘肃省民生改善工作亟待加强;青海省和内蒙古自治区要加大创新投入力度,提高创新能力。

To promote the high-quality development of the Yellow River Basin, it is necessary to construct an evaluation index system for a scientific assessment of such development. Based on the two areas of economic and social development and ecological security, and considering five dimensions of economic development, innovation, improvement of people’s livelihood, environmental conditions, and ecological conditions, this study constructed a high-quality development evaluation index system for the Yellow River Basin. Using the data of nine provinces (autonomous regions) in the Yellow River Basin during 2008-2017, the entropy weight method was used in calculation. The results are as follows: The high-quality development level of the Yellow River Basin basically showed the spatial distribution of “high on both sides and low in the central area,” but the gap was decreasing year by year; The high-quality development level in each province (autonomous region) remained stable in 2008-2010, and continued to grow in 2011-2017, with a high growth rate in 2016; The overall high-quality development level of the basin showed an upward trend, with small fluctuations during 2008-2010 and a significantly increase from 2011. Over the last decade, all five dimensions improved. Accordingly, the study put forward specific suggestions and the directions for further research: (1) Strengthen regional linkages and expand the overall opening-up level of the Yellow River Basin. (2) On the basis of protecting the ecological environment, the provinces (autonomous regions) in western China should develop characteristic industries, combining with their factor endowments. (3) Shandong and Henan Provinces should strengthen the protection of the ecological environment while developing the economy. Shanxi and Gansu Provinces should improve people’s living standards urgently. Qinghai Province and Inner Mongolia Autonomous Region need to increase investments in innovation and improve innovation capacity. Finally,the study proposed the further research directions.

Scientifically identifying the pattern, process, and mechanism of the old-new growth driver conversion in the Shanxi-Shaanxi-Inner Mongolia region is an urgent requirement for narrowing the regional development gap and achieving high-quality development in the region. On the basis of constructing a theoretical framework for regional old-new growth driver conversion and with the aim of promoting regional coordinated high-quality development, this study examined the process of old-new growth driver conversion and the spatiotemporal differentiation mechanism in the Shanxi-Shaanxi-Inner Mongolia region at the city scale in 2005-2019 from the four dimensions of driving force, institution, structure, and mode. The results show that: 1) The level of old-new growth driver conversion in the Shanxi-Shaanxi-Inner Mongolia region showed a trend of first fluctuating and decreasing and then rising rapidly, and the gap of old-new growth driver conversion between cities is gradually widening. 2) The overall level of old-new growth driver conversion in the region is low, showing a core-periphery structure spatially, with the provincial capital cities as the cores. The advantageous and leading areas showed a dotted distribution pattern with provincial capital cities as the cores, and the lagged and medium-level areas are widely distributed in non-provincial capital cities. 3) The negative spatial correlation of old-new growth driver conversion in the region is obvious, showing the spatial differentiation characteristics of cold spot agglomeration and hotspot dispersion, and a health interaction mechanism of old-new growth driver conversion between cities has not yet been formed. 4) The geographical differentiation of old-new growth driver conversion in the Shanxi-Shaanxi-Inner Mongolia region is the result of the comprehensive action of multiple elements, and human capital, urban scale, and the level of informatization are the core driving factors. This study indicates that cultivating innovation talents, enhancing the ability of agglomeration and transformation of innovation resources, and strengthening informatization development are the key paths to promoting the old-new growth driver conversion and coordinated and high-quality development in the region.

Scientific evaluation of the level of high-quality development of the marine economy is the key link to accurately grasping the high-quality development of the marine economy in the context of the New Era. Based on the multi-indicator evaluation models such as panel, threshold, and Bayesian, the article considers the study of the timeliness of indicators and the internal logical connection. It takes the premise-path-the purpose of high-quality development of the marine economy as the analytical framework to evaluate the level and regional differences of high-quality development of marine economy in 11 coastal provinces and cities in China from 2007 to 2017, to analyze its influencing factors and optimize the path selection, etc. The results show that: 1) Through index measurement and comprehensive analysis, the high-quality development of the marine economy in 11 coastal provinces, municipalities and autonomous varies greatly. From the premise of high-quality development, the provinces and cities are stable in development. The basic level is in three distinct echelons; from the path of high-quality development, there are great differences among provinces and cities, Shanghai having the strongest and most stable capacity, Tianjin and Guangdong having stronger and more stable capacity, Guangxi and Hainan having poor and less stable capacity, others having poor but relatively stable capable. From the perspective of high-quality development purposes, the development of provinces and cities is more unstable, achieving minor differences in results. There is no obvious echelon formation, but Guangdong and Zhejiang have a significant trend of improvement. 2) The innovation-driven marine economy has a ‘V’ shape impact on achieving high-quality development of the marine economy. At present, the innovation drive has the most significant impact on the high-quality development of China's marine economy and has greater potential. 3) The optimization of marine economic development structure has a ‘U’ shape impact on the realization of high-quality development of the marine economy. Currently, the structural advantage dividend is not yet obvious, and it is needed to promote structural optimization to cross the next threshold. 4) The improvement of marine economy development efficiency has a positive and significant impact on realizing the purpose of high-quality development of marine economy, and its development foundation is good and has the greatest potential. 5) The optimization of the marine economic market environment presents a positive influence trend of increasing first and then decreasing for the purpose of achieving high-quality development of the marine economy. The market environment dividend is not obvious at present, so it is necessary to push the optimization of market environment to the third threshold.
