基于1996~2011年省际面板数据随机前沿模型计算结果,运用空间计量、协整回归及因果检验实证分析异质劳动与资本集聚对我国经济发展效率的影响机制。结果发现:资本集聚通过影响生产规模中的要素再配置而与规模效应之间存在此消彼长的替代关系,以调整技术进步速度和方向;生产率的提高不在于技能劳动集聚,而在于技能劳动集聚对技术效率和人力资本的溢出效应;资本集聚与技能劳动集聚的非协调演进导致技术进步与人力资本匹配失当是规模效应提高和生产率增长的最大掣肘因素,宏观上表现为规模经济扩张与规模经济效率下降共存。
Based on provincial panel data from 1996 to 2011,this paper analyzes heterogeneous factors agglomeration and their different spillover effects on Chinese economic efficiency by stochastic frontier model. Results show that,firstly there are substitution relationship between capital accumulation and production scale. Secondly,productivity improvement is not in skill-labor concentration,but in technical efficiency and spillover effect of human capital. Thirdly,improper matching between technological progress and human capital is the maximum constraints to productivity growth.
