劳动生产率、产业结构与σ收敛——基于珠江三角洲地区9个城市的研究

Productivity,Industrial Structure and σ-Convergence——Analysis Based on 9 Cities of Pearl River Delta Region

研究了珠江三角洲地区9个城市劳动生产率的σ收敛,考察了城市劳动生产率σ的差异在2000～2010年随时间推移所发生的变化;采用生产结构不平等指数(IIPS)检验了总劳动生产率的σ收敛与产业结构变化的关系。研究表明,总劳动生产率显示出明显的σ收敛,但是分产业的劳动生产率的差异并没有显著缩小,究其原因主要是由于城市资源不断从第一产业向生产率较高的产业转移,而且在发展水平较低的城市表现得更为明显。最后针对珠三角经济一体化发展战略提出政策建议。

This paper estimates the evolution of labor productivity disparities in 9 cities of Pearl River Delta （PRD） Region from 2000 to 2010 according to the concepts of σ - convergence and IIPS. In order to measure the narrowing of inequalities, we examine σ-convergence and reveal that convergence occurs in aggregate labor productivity but not in productivities per sector. The reason comes from a transfer of resources from agriculture towards more productive sectors that has been more pronounced in the poor regions than in the rich ones. At last, this paper provides some useful reference materials promoting economic integration in the PRD.
