广东省经济开放对TFP增长率的影响——基于三重开放视角的实证分析

The Study about the Impact of Guangdong Economic Openness on TFP——From the View of Triple Opening-up

文章从省域经济的三重开放角度出发,以广东省1992年至2009年数据为例,构建了经济综合开放度评价指标体系,并运用熵值法计算各指标权重从而计算出历年各经济开放度。再建立VAR模型,运用脉冲响应函数研究了三重经济开放对广东省TFP增长率的影响。结果发现,国际开放度对TFP增长率的促进作用具有一定的时滞性;省际开放度对TFP增长率产生了较大的正向冲击效应,但持续时间较短;而省内开放度对TFP增长率的冲击产生先负后正的效应,持续时间较长。

From the view of triple opening-up of provincial economy, this paper built the evaluation system of integrated degree of economic openness. And it measured the openness degree of Guangdong Province from 1992 to 2009 with the entropy method. Then it estimated the TFP growth rate based on Cobb-Douglas Production Function. Finally, it analyzed the impact of openness on TFP with impulse response function. It is found that there exists time lag effect of international openness on the TFP growth rate, provincial openness plays a positive role on the TFP growth, but the effect lasts shorter; the inner openness of province makes a positive effect on the TFP growth after a negative effect, and the whole effect lasts long.
