中国工业环境全要素生产率的来源分解——基于要素投入与污染治理的分析

The Sources of China's EnvironmentalTotal Factor Productivity

本文将基于松弛的效率损失测度法与卢恩伯格生产率指数相结合,通过将工业环境全要素生产率指数按照投入要素与产出进行分解,测算中国工业环境全要素生产率的来源。结果发现,2001～2007年中国工业环境全要素生产率有所提高,但受国际金融危机的影响,在2008年下降;工业环境全要素生产率的来源表明,加强污染治理可以有效提升工业环境全要素生产率;投入生产率的来源表明,劳动生产技术的进步是提高工业环境全要素生产率的有效措施;污染治理生产率的来源表明,优先加强COD治理能更有效提升工业环境全要素生产率。

Combining Slacks-based Inefficiency Measurement and Luernberger Productivity Index, by decomposing the environmental total factor productivity into inputs and outputs, this paper measures the sourse of China＇s environmental total factor productivity. Some meaningful findings are made： Environmental total factor productivity in China＇s industrial rose in 2001～2007 but declined in 2008 affected by global financial crisis. In the environmental total factor productivity, the productivity of the inputs accounts 1/3, and pollution control productivity accounts 2/3. In the productivity of inputs, the productivity of capital contributes approximate 1/6, the productivity of labor contributes 5/6. In the environmental total factor productivity, the productivity of COD abatement accounts approximate 2/3, the productivity of SO2 abatement accounts approximate 2/3.
