不同类型技术进步的节能减排绩效及其动态变化

Performance of Energy Saving and Emission Reduction of Different Types of Technology Progress and Its Dynamic Change

运用非参数SML生产率指数模型,测算了1994—2014年中国35个工业行业的基于绿色增长的技术进步,并采用面板模型对按能耗与碳排放分组的行业分别进行能耗强度和CO_2排放强度回归。结果表明:生产前沿的科技创新是推动中国工业绿色全要素生产率提高的主动力,前沿科技创新的节能降耗绩效最高,纯技术效率的CO_2减排绩效最高;技术进步的节能降耗效应与CO_2减排效应具有非对称性,技术进步的CO_2减排绩效大于其节能降耗绩效;能源消费结构调整的CO_2减排绩效大于其节能降耗绩效。

This paper uses the non-parameter SML productivity index model to calculate and decompose the technological progress of green growth in China＇s 35 industries from 1994 to 2014.And it makes the group-level regression analysis for industries with different energy consumption intensity and CO2 emission intensity by using the panel model.The result shows as follows：technological innovation is the main driving force to promote industrys＇ green total factor productivities in China;the energy-saving and consumption-reducing performance of cutting-edge technology innovation is the highest;the pure technology efficiency of CO2 emission reduction is the highest;there is asymmetry in energy saving and CO2 emission reduction effect of technological progress,and technology progress of CO2 emission reduction performance is greater than that of energy saving;the CO2 emission reduction performance of energy consumption structure adjustment is greater than that of energy saving.
