大气污染防治存在两种关键途径,即源头控制和末端治理。通过分析区域能源消费和污染排放绩效,能够明确中国各区域大气污染防治的有效途径。因此,本文运用SBM方法和Luenberger生产率指数(LPI)对大气环境绩效进行测算,并对生产率的变化进行要素和根源分解。研究表明;SO2、一次能源消费以及一次能源相关的碳排放已经成为中国大气环境无效率的主要来源。2006~2013年中国大气环境全要素生产率平均增长1。36%,与能源和污染物相关的生产率呈现“由东南沿海向西部内陆递减”的梯度分布,表明政府应加强对西部地区的环境规制。根据两个关键因素的生产率变化情况将全国分成五个区域类别,各区域应结合自身实际采取多样化政策强化源头控制或末端治理。
<<This paper investigates the key paths for mitigating air pollution following the paths of the source control and end-of-pipe control. We conduct performance analysis in terms of energy consumption and pollution emission from the regional perspective,and identify the appropriate path for each region of China. With SBM and Luenberger productivity indicator(LPI),we assess the atmosphere environment performance and decompose the LPI with regards to input/output variables and productivity change sources. Our findings show that sulfur dioxide,primary energy consumption and energy-related carbon emission have become the main sources of inefficiency in the sense of the atmosphere environment pollution. The average annual productivity change for China is 1.36% over 2006-2013. LPI change associated with energy and pollutant variables shows the gradient which increases from southeast coast to west inland. This pattern implies the government needs to enhance the environmental regulation in the western regions. Moreover,the provinces are divided into five groups to identify the corresponding paths(source or end-of-pipe control). According to our identification,we suggest that local government should perform diversified policies suitably to strengthen source or end-of-pipe governance.
