本土市场规模与地区生产率:对“市场范围”假说的实证检验

Home Market Scale and Regional Productivity:Test of the Hypothesis of Market Scale

本文基于斯密的＂市场范围＂假说,结合我国1990~2011年省级层面的发展数据,运用动态面板估计模型,研究了本土市场规模和地区生产率之间的作用关系,其中特别采用了随机前沿模型（SFA）对地区生产率及其分解进行了测度,所得结论为：无论从总体样本还是分时段样本,本土市场规模对地区技术效率均难以产生显著的促进作用,而对于地区技术进步和生产率而言,具有阶段性特征,即本土市场规模对地区技术进步和生产率的推动作用主要来源于1998年以后的分段样本;同时对人力资本、研发投入、基建设备、对外开放和外商直接投资等控制变量的回归,发现它们对地区生产率及其分解会产生异质性的影响。最后,基于这些结论,提出了相应的对策建议。

Based on the hypothesis of Simith＇s Market Scale and using the panel data set of our province development from 1990 to 2011 and the DPD method ,this paper studies the relationship between home market scale and regional productivity. And especially, it estimates the regional productivity and its separations by SFA. And it finds that no matter using total data or separated timely data, home market scale has no positive effects on regional efficiency improvement. And to regional productivity and technical progress,it fits to the hypothesis of home market scale especially after 1998. Meanwhile,it also tests some control variables such as human resource, R＆D,infrastructures, FDI and so on. Based on all these conclusions, it gives some countermeasures.
