基于我国31个省(市区)1990-2012年的面板数据,采用具有时空特定效应的空间面板数据模型,考察制度要素对我国区域经济增长直接与间接贡献的影响。结果表明,我国各省(市区)制度水平的高低并非随机,而是呈现出显著相似属性的集聚效应;生产要素的空间流动会对相邻省份的经济增长产生带动作用,地区间的经济增长存在显著的正向“邻里”作用,而且制度要素空间外溢性能够为相邻地区的制度水平带来双向的“指向”效应;传统生产要素对经济增长的贡献包含着制度要素的作用,制度要素对经济增长存在间接贡献,其作用更具有解释力。制度创新及制度要素的空间均衡发展是影响我国区域经济发展的重要因素。未来我国的区域经济均衡发展战略应该转向以促进劳动力等生产要素的自由流动,而不是单纯的依靠投资拉动来推动经济增长。
Based on the panel data of 31 provinces (urban areas) in China from 1990 to 2012, a spatial panel data model with time-space-specific effects was used to examine the influence of institutional factors on the direct and indirect contribution of regional economic growth in China. The results show that the institutional level of provinces (municipalities) in our country is not random, but shows a clustering effect with significant similarities. The spatial mobility of factors of production will have an effect on the economic growth of neighboring provinces and the economic growth among regions Significant positive “neighborhood ” effect, and the spillover of institutional elements can bring two-way “pointing ” effect to the institutional level of neighboring regions; the contribution of traditional factors of production to economic growth includes the function of institutional factors , Institutional factors have an indirect contribution to economic growth, and their role is more explanatory. Institutional innovation and the balanced development of institutional elements are the important factors affecting the development of regional economy in our country. In the future, the strategy of balanced development of regional economy in our country should be shifted to promote the free flow of productive factors such as labor force instead of relying solely on investment to promote economic growth.
