摘要
文章利用岭估计法对包含制度变量的人力资本外部性内生生产函数模型进行参数估计,结果表明,1979～2004年,中国人力资本存量的产出弹性为0.632,29%的经济增长得益于人力资本的不断积累;人力资本水平不断提高对中国经济增长有着较强的正的外部性影响,对经济增长的贡献率为17.67%。三大区域中,东部人力资本水平及其产出弹性最大,西部人力资本存量最小但其产出弹性最高,而且区域内部差异最大。投资对三大区域经济增长的不同影响主要来自于不同区域中制度因素引起的投资效率的差异;市场经济体制改革以来,区域之间人力资本及投资对经济增长的影响的差距缩小,全要素生产率的差异是造成区域经济差异不断扩大的主要原因。
The article constructs a production function and estimates the parameters by using the ridge regression.The results are as follows:(1)the economic growth during 1979～2004,with output elasticity of human capital stock 0.632,29%,is due to the accumulation of human capital;(2)the increase of human capital produces great positive effect on economic growth,with a contribution of 17.67% to it;(3)the influences of human capital on economic growth between regions and within regions are different;(4)the difference of investment among regions mainly comes from the difference of marginal efficiency of investment;(5)since the market-oriented reform,the great difference in TFP has become the main reason for the enlarging regional inequalities.
