京津冀协同发展背景下的金融聚集与经济收敛——京津冀城市群与长三角城市群的对比分析

Financial Agglomeration and Economic Convergence under Background of Collaborative Development in Jing-Jin-Ji Area:Comparison between Metropolitan Area in Jing-Jin-Ji and Yangtze River Delta

利用2000—2014年京津冀城市群和长三角城市群的38个城市的空间面板数据,从金融聚集和经济收敛的视角,探讨了京津冀城市群的经济和金融发展失衡的深层次原因以及一体化背景下的协同发展路径,并将京津冀城市群和长三角城市群进行了对比分析。结果表明:两城市群的经济和金融呈不同的空间辐射模式;具体而言,京津冀城市群的金融效率和金融规模存在显著的σ收敛和β收敛,但是经济增长的σ收敛和β收敛不仅未呈现出趋同效应,反而表现出发散特征,表明河北在信贷投入不足的情况下仍存在严重的金融资源流失现象,金融对当地经济贡献微弱;与之形成鲜明对比的是,长三角城市群的金融效率和金融规模的σ收敛呈发散趋势,但其β收敛和经济增长的σ收敛和β收敛均呈现出趋同效应,表明长三角城市群金融聚集的溢出效应促进了邻近区域的经济增长。

Using the spatial panel data of 38 cities in metropolis circle in Jing-Jin-Ji and Yangtze River Delta from 2000 to 2014,this paper deeply explores the reason of the imbalance of economy and finance,and the collaborative development path for Jing-Jin-Ji from the perspective of financial agglomeration and economic convergence,and compares the metropolis circle in Jing-Jin-Ji with that in Yangtze River Delta.The result shows as follows：financial agglomeration and economic convergence of two metropolitan circle present different spatial radiation patterns;in Jing-Jin-Ji area,financial efficiency and scale take on significantσconvergence andβconvergence,but theσconvergence andβconvergence of economic growth present the divergence effect,not the convergence effect,which indicates that the phenomenon that financial resources lose is still severe in Hebei province although credit input is inadequate,and the contribute of finance to local economy is few;in contrary,σconvergence of financial efficiency and scale diverge in Yangtze River Delta,butβconvergence of them as well asσconvergence andβconvergence of economic growth also have convergence effects,which indicates that the spillover effect of financial agglomeration in Yangtze River Delta promotes the economic growth of adjacent area.
