本文运用非参数DEA分析方法,将长三角地区的经济增长分解为物质资本积累、效率改善、技术进步和人力资本投入等四部分,利用空间统计与空间计量经济分析技术,采用绝对收敛方程考察了长三角经济增长与这四类因素的收敛效应。结果表明,物质资本所贡献的经济增长主导着长三角各县市区的实际经济增长;长三角区域经济增长存在显著的空间依赖性,这种空间效应对经济增长的变化趋势产生明显影响;物质资本积累是惟一使得长三角地区间差距缩小的因素,主导着长三角地区经济收敛的方向;人力资本、效率改善与技术进步等使得长三角经济增长趋异,对长三角的经济差距也产生了深刻的影响。
In this paper, the non-parametric DEA method is used to decompose the economic growth in the Yangtze River Delta into four parts: physical capital accumulation, efficiency improvement, technological progress and human capital investment. Using the method of spatial statistics and space econometrics, the absolute convergence equation Economic Growth in the Yangtze River Delta and the Convergence Effect of these Four Factors. The results show that the economic growth contributed by material capital dominates the actual economic growth of all counties and districts in the Yangtze River Delta. There is a significant spatial dependence of economic growth in the Yangtze River Delta. Such spatial effect has a significant impact on the trend of economic growth. Capital accumulation is the only factor that narrows the gap between regions in the Yangtze River Delta and dominates the direction of economic convergence in the Yangtze River Delta. Human capital, efficiency improvement and technological progress have made the economic growth in the Yangtze River Delta diverge, resulting in the economic disparity in the Yangtze River Delta profound impact.
