【摘要】 文章基于SBM方向性距离函数与全域Malmquist-Luenberger(GML)指数,测算了2001-2016年浙江省28个制造业行业的碳生产率,并检验了其收敛性。研究结果表明:整体而言,浙江省制造业的碳生产率呈增长趋势,其增长主要归因于技术变化,而技术效率没有发挥出应有的提升碳生产率水平的作用;浙江省制造业的碳生产率没有呈现出显著的σ收敛,但具有绝对β收敛和条件β收敛,相对污染类行业和相对清洁类行业呈现异质性的收敛特征;企业规模和资本深化对碳生产率增长的影响显著为正,而能源消费结构对其的影响显著为负。因此,推进技术创新、扩大企业规模、优化能源结构和促进资本深化是提高浙江省制造业碳生产率的关键。更多还原

【Abstract】 Applying Slack-based directional distance function and Malmquist-Luenberger productivity index,we measure carbon productivities of 28 manufacturing sectors in Zhejiang province from 2001 to 2016,and examine the convergence across the manufacturing sectors. We find that the carbon productivities of manufacturing sectors in Zhejiang province show an increasing tendency on the whole,and technology change is the leading contributor to the increase,while technical efficiency does not play its due role in improving the carbon productivities. Moreover,there is no significant σ convergence across the manufacturing sectors in Zhejiang province,but there exists the absolute β convergence and the conditional β convergence.There is heterogeneity in convergence characteristics between pollution sectors and clean sectors. Our findings also show that firm size and capital deepening have significant positive effects on the growth of carbon productivities of manufacturing sectors,whereas energy consumption structure has a significant negative effect. Therefore,promoting technological innovation and capital deepening,expanding firm size as well as optimizing energy consumption structure are the key points to improve carbon productivities of manufacturing sectors in Zhejiang province.更多还原
