基于改进柯布-道格拉斯函数的生产要素对我国经济增长贡献的研究

The Contribution of Production Factors to Economic Growth Based on Geographical Weighted Regression Model

在全局C-D生产函数的基础上,运用地理加权回归模型,建立局部GWR C-D生产函数模型,并以全国31个省、市、区经济社会和建设用地等数据为基础,研究生产要素对我国经济增长的贡献及其地域差异.结果表明,我国省、市、区经济空间异质性特征明显,经济增长处于报酬递增阶段;生产要素对各省、市、区经济增长的贡献表现出显著的空间集聚性,其中西部地区资本要素的贡献较高,东部地区土地要素的贡献较高,中部和西南地区劳动力的贡献较低.

Production factor is an important aspect of regional economic growth research.On the base of CobbDouglas production function,Geographical Weighted Regression Model is used to compute provincial production factor’s contribution rate to economic growth in 2006.The method can estimate every province’s local production factor contribution rate to economic growth.The result can also conform to reality that western regions are rich in resources but lack of capital,and eastern regions go short of land resources.
