基于技术选择差异的我国区域全要素生产率分析

Research on Total Factor Productivity Rooted in Different Technology Selection among Chinese Regions

利用我国1996-2011年29省面板数据,构建区域异质性随机前沿生产函数模型,并解构全要素生产率变化。结果发现：异质技术前沿下区域TFP增长率的变化趋势更契合地区经济发展差异;东部TFP增长呈稳中有降的“下台阶型”变化,中部呈稳中有升的“上台阶型”增长,西部则呈持续的“锯齿型”波动;相对于区域经济发展阶段,东西部技术选择存在欠适宜性。

This paper constructs different production models using panel data of 29 provinces from 1996 to 2011,and then decomposes TFP growth. Result shows that the TFP trends from different frontier models are more in line with non-balanced regional economic development; the Eastern TFP has ＂down step＂change,the Central,a steadily increasing ＂on stage＂;while the western is continued wave of ＂zigzag＂; diseconomies of scale has been the biggest constraints in each TFP;compared to its economic development,the technology selection of Eastern and Western is less feasible.
