考虑经济增长的阶段性特征和空间效应是分析我国区域经济问题的关键。本文运用SUR模型衡量了经济增长的阶段性特点,运用修正后的G统计量和空间滞后模型分析了空间效应对区域经济增长趋同的影响,并通过分解空间结构矩阵分析了不同区域间的空间效应关系。结果表明:我国区域空间存在着显著的中心、次级和外围空间俱乐部趋同效应,各趋同俱乐部之间存在着不同水平的空间依赖关系,中心区域和次级区域之间的空间依赖性比较突出,外围区域市场区效应影响有限,次级区域和外围区域之间的空间依赖性以负作用为主。因此,应进一步提高我国区域发展中的空间效应,尤其是对于次级区域和外围区域而言,在制定区域发展战略中应予以足够重视。
Considering the phasic features and spatial effects of economic growth is the key to analyzing the regional economic problems in our country. This paper uses the SUR model to measure the stage characteristics of economic growth, analyzes the effect of spatial effect on the convergence of regional economic growth by using the modified G statistic and spatial lag model, and analyzes the spatial effect of different regions by decomposing the spatial structure matrix relationship. The results show that there is a significant convergence effect of the central, subordinate and peripheral space clubs in China’s regional space, and there are different levels of spatial dependence among the converging clubs. The spatial dependence between the central and subordinate regions is prominent, The market area effect in the peripheral area has a limited impact, and the spatial dependence between the secondary area and the peripheral area is dominated by the negative effect. Therefore, the space effect in the development of our region should be further enhanced, and especially in the subregional and peripheral regions, enough attention should be paid in formulating the regional development strategy.
