【摘要】：环境的外部性使包含环境影响的生产率度量一直是个难题,而此类研究对推动我国农业可持续发展具有重要意义。本文提出了一种度量和评估包含环境影响的农业生产率方法,在本研究中,环境的外部性通过定义一个包含市场产出和污染产出的总产出而纳入分析框架,用总产出代替传统TFP计算中的产出,包含环境影响的全要素生产率公式得以建立。利用基于单元的综合调查评价法计算了1990-2008年我国主要农业污染物排放数量,并在此基础上度量了基于环境修正的我国农业全要素生产率。研究表明在1990-2008年间我国经环境调整后的农业生产率增长呈现减小趋势,农业环境污染使农业生产率增长降低0.09%-0.6%,且呈现较大的时期变化;依据不同环境污染价值损失评估法,环境对农业全要素生产率的修正会带来或高或低的结果。为了更准确地度量环境对农业全要素生产率的影响,需要进一步探索环境污染价值评估方法,完善我国农业环境监测体系。
[Abstract]:The externality of the environment makes it difficult to measure the productivity that includes the environmental impact. This kind of research is of great significance to promote the sustainable development of agriculture in China. This paper proposes a method of measuring and evaluating agricultural productivity including environmental impact in this study. The externality of the environment is included in the analytical framework by defining a total output that includes market output and polluting output, replacing the output in the traditional TFP calculation with total output. The formula of total factor productivity (TFP) including environmental impact was established. The discharge quantity of main agricultural pollutants in China from 1990 to 2008 was calculated by using the method of integrated investigation and evaluation based on unit. On this basis, we measure the total factor productivity of agriculture based on environmental correction. The research shows that the growth of agricultural productivity after environmental adjustment shows a decreasing trend in 1990-2008. Agricultural environmental pollution reduced the growth of agricultural productivity by 0.09-0.6, and showed great changes in the period. According to different environmental pollution value loss assessment methods, the environmental modification of agricultural total factor productivity will bring about higher or lower results. In order to measure the impact of environment on agricultural total factor productivity more accurately. It is necessary to further explore the evaluation method of environmental pollution value and improve the agricultural environment monitoring system in China.
