中国工业分行业能源CES生产函数估计与选择

Estimation and Selection of Energy CES Production Function for China’s Industrial Subsector

文章测算了1980—2015年中国工业分行业投入产出数据,并估计了上述行业的能源CES生产函数,结果发现：（KE）L函数形式比（KL）E和（LE）K形式更符合中国工业分行业的实际情况,各行业的资本-能源替代弹性范围为国026,资本能源合成品与劳动的替代弹性范围为步率为0.109~1.093;在（KE）L函数形式下,中工业分行业的能0.0源21增~1强.型技术进技0.78%~42.6%,资本增强型技术进步率为-1.3%^-23.6%,劳动增强型术进步率为2.6%~14.2%。

This paper measures and calculates the input-output data of China＇s industrial subsector from 1980 to 2015, and estimates the energy CES production function of theses industries. The result shows that（KE） L function form is more suitable than（KL） E and（LE） K for China＇s industrial actual situation; the capital-energy substitution elasticity range of various industries is0.021~1.026, and the alternative elasticity of capital energy composite and labor is 0.109~1.093; under（KE） L function, the energy-enhanced technology progress rate of China＇s industrial subsector is 0.78% ~ 42.6%, the capital-enhanced technology progress rate-1.3% ^-23.6%, and the labor-enhanced technology progress rate 2.6%~14.2%.
