摘要
采用DEA-Malmquist函数对中国塑料制品产业的效率和全要素生产率指数演变进行研究,研究结果发现,中国塑料制品产业的效率呈波动上升的趋势,综合效率、规模效率上升趋势明显,纯技术效率有待优化;全要素生产率指数可划分为波动上升阶段和波动下降阶段,技术进步指数在全要素生产率中贡献较大。
The DEA-Malmquist function is used to study the efficiency of China's plastic products industry and the evolution of total factor productivity index.The results of the study found that the efficiency of China's plastic products industry showed a rising trend of volatility.The overall efficiency and scale efficiency had an obvious upward trend,and pure technical efficiency needed to be optimized.The contribution to total factor productivity is greater.
