【摘要】：区域经济收敛性一直是研究热点,动态外部性成为关注焦点.通过分析动态外部性与城市群经济空间收敛机理,构建动态经济权重模型,判断区域经济空间关联性.然后分析面板数据平稳性,结合动态空间面板模型,计算技术空间溢出水平,准确判定区域经济收敛性.最后,以环长株潭城市群例证该模型和方法的可行性,并得出:①空间外部性是影响经济收敛的主要因素,技术空间溢出是关键,SDM较好地描述了此收敛性;②使用SDM分析时必须确保面部数据的平稳性,剔除短期周期性误差对区域经济收敛性的不当影响;③空间权重受地理邻近、产业结构和市场潜能的交互影响,是动态的,且对经济收敛结果影响很大;④环长株潭城市群存在明显经济收敛机制,技术空间溢出效应较显著,仍需要进一步消除限制知识和贸易自由流动的行政壁垒和交通瓶颈促进城市群技术进步和经济协同发展.
[Abstract]:Regional economic convergence has been a hot topic, dynamic externality has become the focus of attention. By analyzing the dynamic externality and the spatial convergence mechanism of urban agglomeration economy, the dynamic economic weight model is constructed. Judge the spatial relevance of regional economy. Then analyze the stability of panel data, combined with the dynamic spatial panel model, calculate the level of technology spatial spillover, determine the convergence of regional economy accurately. Finally. The feasibility of the model and method is illustrated by the urban agglomeration around Changzhou-Zhuzhou, Zhuzhou and Xiangtan, and it is concluded that the spatial externality of 1 is the main factor affecting the economic convergence, and the technology spatial spillover is the key to describe the convergence. (2) when using SDM analysis, the stability of facial data must be ensured, and the improper influence of short-term periodic error on regional economic convergence should be eliminated. (3) the spatial weight is dynamic and has great influence on the result of economic convergence because of the interaction of geographical proximity, industrial structure and market potential. 4Chang-Zhuzhou-Xiangtan urban agglomeration has obvious economic convergence mechanism, and the technology spatial spillover effect is obvious. There is still a need to further remove administrative barriers and transport bottlenecks that restrict the free flow of knowledge and trade to promote technological progress and economic synergy in urban agglomerations.
