电力行业碳排放的影响因素——基于长江经济带空间动态面板的实证研究

The Influencing Factors on the Carbon Emission of Electric Power Industry:An Empirical Study Based on Yangtze Economic Belt Spatial Dynamic Panel

本文基于Malmquist指数方法,测算了长江经济带电力行业绿色全要素生产率,然后运用STIRPAT模型和空间动态面板计量方法研究了长江经济带电力行业碳排放的影响因素。实证研究结果表明:空间因素对于长江经济带电力行业的碳排放具有不可忽视的作用,域内常住人口数量、城镇化水平和人口受教育程度的提高对电力行业碳减排有一定的促进作用;人均收入的提高加剧了电力行业碳排放;各省市的绿色全要素生产率、非化石能源发电比重、企业技术进步和研发水平的提高对电力行业碳减排有正向的促进作用,其中企业研发水平的提高对碳减排的促进作用最大,第二产业比重的提高增大了碳排放。

Based on Malmquist Index method, this paper calculates the green total factor productivity of the electric power industry in the Yangtze Economic Belt. Then it applies STIRPAT model and the spatial dynamic panel data method to analyze the influencing factors on the carbon emission of the electric power industry in the Yangtze Economic Belt.The empirical result reveals that spatial factors play an indispensable role in this industry of the zone. The number of permanent residents in the zone, the urbanization level and the education level have a positive effect on the carbon emission reduction of the industry. The increase of wealth per capita exacerbates the carbon emission. The green total factor productivity of the provinces, the ratio of non-fossil resources in power generation as well as the enterprise technical progress and RD have a positive effect on carbon emission reduction in the electric power industry. Among which the enterprise RD plays the most decisive role. The increasing proportion of the secondary industry enlarges the carbon emission.
