中国工业行业资本-劳动替代弹性估计及影响因素研究

An Estimation of the Capital-Labor Substitution Elasticity and Its Influencing Factors in China's Industrial Sector

基于超越对数生产函数的随机前沿模型估计2001—2015年中国工业行业的资本-劳动替代弹性,并对其影响因素进行分析,结果表明:劳动密集型行业的资本-劳动替代弹性普遍高于技术密集型行业,而后者又普遍高于资本密集型行业;行业开放程度、研发密度、产权属性、资本-劳动比、资产负债率、《劳动合同法》实施以及金融危机等因素都会影响资本-劳动替代弹性。

Based on stochastic frontier model of trans-log production function,this paper makes an estimation on the capitallabor substitution elasticity of industrial sectors in China from 2001 to 2015 and an analysis on the influencing factors. The results show that： the capital-labor substitution elasticity of most industries in the labor-intensive industry group is greater than that in technology-intensive industry group,while the latter is greater than that in capital-intensive industry group. The openness,R＆D intensity,nature of property right,capital-labor ratio,debt to assets ratio of the industries,the implementation of Labor Contract Law and the financial crisis can all influence the capital-labor substitution elasticity.
