摘要:

“行政区经济”作为行政区划框架下自身发展和区域竞争相互作用的经济运行现象,对区域协调发展影响深远。论文立足于区域经济一体化的视角,构建基于“行政区经济”函数和改进潜能模型的“行政区经济”测度模型,以成德绵地区为例,定量刻画其2005—2018年“行政区经济”约束强度的时空演化特征。研究表明:① 研究期内成德绵地区“行政区经济”约束强度历经“累积上升—快速下降—波动起伏”3个阶段,行政区划对经济一体化的刚性约束总体上呈下降趋势,区域一体化态势明显;② 2009年是其变化的拐点(峰值),各阶段“行政区经济”约束强度变化与政策以及行政区划调整耦合性较强,“行政区经济”测度模型具有较好适用性和合理性;③ 2005—2018年间研究区“行政区经济”类型结构具有阶段性稳步降低的特点,高强度型和60%的中强度型政区转为较低强度型政区,较低强度及以下类型政区占比由51.7%提升至91.4%,表明“行政区经济”的约束强度明显降低,区域一体化水平显著提升;④ 成德绵地区“行政区经济”空间格局经历了“中心极化—中部辐射递减—外围塌陷”的过程,研究区在区域协调发展方面采取了有效的措施且效果显著,推动“行政区经济”重心向南偏西3°方向位移10.08 km。未来还需通过改革行政组织结构和适时推进行政区划调整等途径优化体制机制,弱化行政区划约束,构建良好的一体化发展模式。

Abstract:

As an economic phenomenon characterized by the interaction of self-governance of development and regional competition under the framework of administrative divisions, "administrative regional economy" (ARE) has a profound impact on regional coordinated development. With the perspective of regional economic integration, this study constructed an ARE measurement model (AREM) based on ARE function and improved potential model, and took the Chengdu-Deyang-Mianyang region as an example to quantitatively describe the spatiotemporal evolution of the constraint strength of ARE from 2005 to 2018. The results show that: 1) In 2005-2018, ARE of the study area experienced three stages of development—overall rise-rapid decline-fluctuation, and the rigid constraint of administrative divisions on economic integration generally declined, with a clear regional integration trend. 2) 2009 was the inflection point (peak) of the ARE change, and the various stages of the ARE change were strongly coupled with policy and administrative division adjustments, indicating that AREM has reasonable applicability. 3) The transition of ARE type steadily took place during 2005-2018: high-intensity and 60% of medium-intensity cities transformed into low-intensity cities, and the proportion of low-intensity cities increased from 51.7% to 91.4%. This shows that ARE has decreased significantly and the level of regional integration has increased. 4) The spatial pattern of ARE in the study area experienced the process of central polarization-central to peripherial decline-peripheral collapse, and effective measures were taken in terms of regional coordinated development with remarkable results, which promoted the displacement of ARE's center of gravity to the south (3° west) by 10.08 km. In the future, it is necessary to optimize the regional system of the Chengdu-Deyang-Mianyang region by reforming the administrative structure and timely promoting the adjustment of administrative divisions, weakening the restriction of administrative divisions, and building an integrated development model.
