全球制造业传统与环境生产率变化及收敛性的比较论证

A Comparative Study on the Change and Convergence of Global Manufacturing Tradition and Environmental Productivity

文章旨在通过2000-2009年期间数据研究制造业在全球经济体以及不同行业之间传统生产率以及能源生产率的变化趋势以及收敛特征。相比于传统生产率,在核算能源生产率过程中纳入了二氧化碳排放量等非期望型产出。分别采用DEA-Malmquist以及Global Malmquist Luenberger指数法测算两类生产率指数并进行比较分析,进而对分经济体以及分行业两类生产率进行了收敛性的检验。研究指出制造业在经济体之间以及行业之间的δ收敛特征均不明显,但除了重工业的传统生产率,其他分经济体以及分行业之间两类生产率都存在显著的绝对β收敛以及条件β收敛。总体上能源效率的收敛速度低于传统效率,但在不同行业及经济体之间,收敛的态势与表现存在较大的差异。

This paper aims to study the changing trend and convergence characteristics of traditional productivity and energy productivity of manufacturing in the global economic entities and among different industry sectors in 2000-2009.Compared with traditional productivity,the undesired output,such as carbon dioxide emissions,is included in the calculation of energy productivity.Dea-M almquist index and Global M almquist Luenberger index were respectively used to calculate and compare the two productivity indexes,and then the convergence test was carried out for two types of productivity in different economic entities and industry sectors.The study points out that theδconvergence of manufacturing between economic entities and industriy sectors is not obvious,but except the traditional productivity of heavy industry,There is absoluteβconvergence and conditionalβconvergence in productivity in other economies and between industries.In general,the convergence rate of energy efficiency is lower than that of traditional efficiency,but there are great differences between different industries and economic entities.
