中国林产工业绿色全要素生产率测算——基于制造业31个分行业的面板数据

基于2012-2019年中国制造业行业数据，在投入产出指标体系中，以能源消耗作为生产要素投入、以CO₂排放量作为非期望产出，采用ML生产率指数法测算林产工业及制造业分行业GTFP指数。结果表明，中国林产工业GTFP增速处于制造业中等水平，且增速逐渐减缓；纯技术进步是GTFP指数增长的主要动力，纯效率下降是GTFP指数增长减缓的主要原因；传统TFP指数过高地估算了行业经营效益，GTFP指数能更真实地反映行业发展状况。因此，促进林产工业GTFP增长和实现高质量发展，既要重视内部自主创新，也要重视内部技术推广与制度建设。

Green Total Factor Productivity of Forest Products Industry in China——Panel Data Based on 31 Sectors of Manufacturing Industry

Based on the data of China manufacturing industry from 2012 to 2019,taking the energy consumptions as the productive input and CO₂ emission as undesirable output in the input-output index system,the green total factor productivity (GTFP) of forest product industry and other industries within the manufacturing industry were calculated through Malmquist-Luenberger (ML) productivity index.The results showed that the growth rate of GTFP in China forestry product industry was at a low level inmanufacturing industry,and the growth rate was gradually slowing down; pure technical change was the main driving force of GTFP growth,and the decline of pure efficiency was the main reason for the slowdown of GTFP growth rate.The traditional total factor productivity index overestimated the operating efficiency of the industries,and GTFP index could more truly reflect the development of the industries.Therefore,promoting GTFP and achieve high-quality development of forestry product industry should not only pay attention to internal independent innovation and external technology introduction,but also to internal technology innovation promotion and system construction,as well as the optimization and innovation of production scale.
