提高碳生产率成为实现二氧化碳减排与经济可持续增长双赢目标的重要途径。本文将能源和人力资本引入C-D生产函数推导碳生产率决定方程,使用省级面板数据检验清洁能源使用与要素配置结构的碳生产率效应。结果显示:在全国层面,清洁能源使用对于碳生产率的改善效应业已显现,且在清洁能源发展不同水平地区存在不容忽视的差异;要素配置结构是影响碳生产率的重要因素,资本-能源比和劳动-能源比的提高将有利于碳生产率增长,近年来中国劳动-能源比持续下降对碳生产率造成的不利影响需引起重视;教育水平提升促进了碳生产率增长,但其贡献程度较小;“干中学”并未如理论预期对碳生产率增长产生正向影响。本文研究意味着逐步扩大清洁能源使用规模、审慎调控要素配置结构是保证碳生产率持续增长的重要手段。
Increasing carbon productivity has become an important way to achieve a win-win goal of reducing carbon dioxide emissions and sustainable economic growth. In this paper, energy and human capital are introduced into the C-D production function to derive the carbon productivity determination equation, and the provincial panel data is used to test the carbon productivity effect of the clean energy use and factor allocation structure. The results show that: at the national level, the effect of clean energy use on carbon productivity has emerged, and there are important differences in the development of clean energy at different levels; factor allocation structure is an important factor affecting carbon productivity, capital-energy ratio and labor - The increase in energy ratio will be conducive to the growth of carbon productivity. In recent years, the negative impact of the continuous decline of China’s labor-energy ratio on carbon productivity needs to be emphasized. The improvement of education level has promoted the growth of carbon productivity, but its contribution is small. Doing Middle Schools "did not have the positive impact of carbon productivity growth as expected. The research in this paper means to gradually expand the use of clean energy and prudently control the allocation of factors is an important means to ensure the continuous growth of carbon productivity.
