Spatial Spillovers and the Convergence of Regional Economic Growth: A Case Study Based on the Yangtze River Delta

空间外溢与区域经济增长趋同——基于长江三角洲的案例分析(英文)

Spatial club convergence means that the economic growth of a group of regions that have similar initial conditions and structural characteristics and are spatially adjacent will gradually converge on the same steady state. As a new field in research on the club convergence of regional economic growth, spatial club convergence works on a mechanism whereby spatial spillovers drive the localized growth of the regional economy, leading to spatial club convergence. Using a theoretical model of regional economic growth that includes spatial spillovers, this study shows that these spillovers can lead to spatial club convergence. Our empirical analysis of regional economic growth in the Yangtze River Delta in 1990-2007 also shows that spatial spillovers can affect regional economic growth, and that spatial club convergence does exist. When the spatial spillover factor is taken into account, the speed of spatial club convergence in the Yangtze River Delta is 1.57 percent.

空间俱乐部趋同是指经济增长初始条件和结构特征相似且空间上相邻的一组区域的经济增长收敛于相同的稳态,是区域经济增长俱乐部趋同的一个新研究领域,其发生机制是空间外溢促成区域经济出现地方化增长,进而导致空间俱乐部趋同。运用包含空间外溢的区域经济增长理论模型可以证明,空间外溢有可能导致空间俱乐部趋同。对中国长江三角洲1990—2007年区域经济增长过程所做的经验分析也表明,空间外溢对区域经济增长确有影响,空间俱乐部趋同客观存在。在考虑空间外溢的情况下,长江三角洲的空间俱乐部趋同速度为1.57%。
