基于Malmquist生产率测度的长三角石油石化产业发展效率评价研究

Evaluation Research of Development Efficiency of Petroleum and Petrochemical Industriesin Yangtze River Delta Based on Malmquist Productivity Index

摘要:

提升长三角石油石化产业发展效率,是实现产业转型升级,推动长三角供给侧改革的重要举措,而生产率的提升是其核心。基于Malmquist生产率指数法,测度了长三角石油石化产业全要素生产率及其分解指标,研究表明,长三角整体生产率不断下滑,呈现“轻视技术创新,生产率持续下滑”的低效率发展趋势；而两省一市的分地区研究呈现出“生产率大幅波动,轻视技术创新”的低效率发展倾向。并分析了原因及内在机理,提出相应对策。这对于审视和推动石油石化产业的技术进步和发展效率提升具有重要意义。

Abstract:

Improving the development efficiency of petroleum and petrochemical industries in the Yangtze River Delta is an important measure to achieve transformation and upgrading and promote the supply-side reform. The improvement of productivity is the core. Based on Malmquist productivity index, we measure TFP and its decomposition of petroleum and petrochemical industries in Yangtze River Delta. From the analysis, we find that the change rate of TFP shows a decreasing trend in the whole Yangtze River Delta. And it shows a “ignore the technological innovation, productivity descending” low-efficiency development trend. While the study of the two provinces and one city shows a “sharp fluctuations in productivity, ignore the technological innovation” low-efficiency development trend. We analyze the reason and the inner mechanism, and puts forward the countermeasures. It has a great significance to review and promote technological progress and development efficiency of petroleum and petrochemical industries.
