要素贡献、规模报酬与中国地区经济增长——基于panel data的实证分析

Contributions of Factors, Returns to Scale and China’s Regional Economic Growth——Empirical Analysis Based on Panel Data

论文选用包含人力资本的柯布一道格拉斯生产函数，使用中国各省份1979-2005年的经济统计数据，分析了中国各区域的要素产出弹性系数和规模报酬情况。研究表明：东部地区已经呈现规模报酬递减的现象，而中西部地区规模报酬呈递增的态势，因而，从投资流向的选择来看，资本投向中西部地区将会更有效率地促进中国经济的增长，并有助于中国地区经济差距的缩小。

Based on the human-capital augmented Cobb-Douglas production function and the provincial economic statistics of China from 1979 to 2005, the paper estimates the elasticity coefficient of output and the coefficient of returns to scale. Through the research, we draw the conclusion that there is decreasing returns to scale in the eastern regions as well as increasing returns to scale in the middle and western regions. In order to promote the economic growth and decrease the regional disparity efficiently, we should invest in middle and western regions prior to eastern regions.
