根据经济增长分解框架,本文将1989～2007年长三角各地区劳均产出增长分解为技术效率提高、技术进步以及资本深化三个因素。在此基础上,运用收敛性检验框架分析了各个因素对产出的影响。从分解的各个因素来看,技术效率提高和资本深化对劳均产出起了收敛作用,技术进步对劳均产出起了发散作用。在三个因素中,对劳均产出增长影响最大的是技术进步因素。总体而言,1989～2007年间,尽管技术进步对劳均产出收敛性产生消极作用,但是效率提高和资本深化的收敛作用最终使得劳均产出产生了收敛性。
According to the framework of economic growth decomposition, this paper decomposes the growth of output per worker in the various regions of the Yangtze River Delta from 1989 to 2007 into three factors: technological efficiency improvement, technological progress and capital deepening. Based on this, we use the convergence test framework to analyze the impact of various factors on output. Judging from the various factors of decomposition, the improvement of technical efficiency and capital deepening have played a role in the convergence of labor productivity and the technological progress has played a divergent role in labor productivity. Among the three factors, the most significant contributor to the growth of labor output per head is the technological advancement factor. In general, although technological progress had a negative effect on labor productivity convergence from 1989 to 2007, convergence of efficiency and capital deepening finally led to the convergence of labor output per worker.
