摘要:

区域经济一体化已成为中国推动区域高质量发展的必由之路,但民营企业投资视角的相关研究罕见。论文运用统计分析和社会网络分析等方法,通过分析2013—2021年兰西城市群民营企业投资网络的演化过程,研究该区域经济一体化进程,并尝试进行机制探讨。结果表明:① 兰西城市群已处于工业化中期发展阶段,但民营企业投资网络仍表现出明显的省际“双核分离”结构,青海省部分一体化水平相对较高,城市群内不同产业的企业投资网络存在较大差异;② 民营企业投资网络“双核分离”结构的形成主要受到当前区域所处发展阶段的影响,省会城市仍以极化作用为主,导致企业跨省投资联系极弱;③ 行政区经济与制度厚度分别通过外部环境与内部决策对民营企业跨省投资施加阻滞作用。根据上述结论,从兰西城市群较低的区域经济一体化水平出发,提出相关政策建议,推动形成以高质量发展为目标的省际互补的区域经济布局。

Abstract:

Regional economic integration has become a necessary path to promote regional high-quality development in China, but relevant studies from the perspective of private enterprise investment are rare. Using statistical analysis and social network analysis methods, we analyzed the process of regional economic integration through the evolution of private enterprise investment network in the Lanzhou-Xining (Lan-Xi) urban agglomeration from 2013 to 2021, and explored the mechanism of change. The study showed that: 1) The Lan-Xi urban agglomeration was in the middle and late stage of industrialization, but the private enterprise investment network still showed an obvious inter-provincial "dual-core separation" structure, with a relatively high level of integration in Qinghai Province, and there were large differences in the inter-provincial investment behavior of different industries within the urban agglomeration. 2) The formation of the dual-core separation structure of the private enterprise investment network was mainly influenced by the current development stage of the region, and the provincial capital cities played a dominant role in this polarization, leading to extremely weak inter-provincial investment ties. 3) The administrative region economy and institutional thickness exerted a deterrent effect on the inter-provincial investment of private enterprises through external environment and internal decision making, respectively. Based on the above conclusions, starting from the low level of regional economic integration in the Lan-Xi Urban Agglomeration, this paper puts forward relevant policy recommendations to promote the formation of inter-provincial complementary regional economic layout with the goal of high-quality development.
