摘要: China is the most populous country in the world, and agriculture has played a large role in the country’s remarkable economic achievements. However, the high levels of pollution and emissions from agriculture pose a threat to the nation’s food and ecological security. Using a global weighted Russell distance function model, this paper attempts to provide strategies for the green development of China’s agriculture by investigating the historical green total factor productivity. The results show that (1) during the sample period, China’s agricultural green total factor productivity (AGTFP) showed a u-shaped trend, and the turning point was 2010. Technological progress in terms of agricultural output, energy use and pollutant treatment was the most powerful factor of growth after 2010, while the technological retrogression in terms of capital use was the main obstacle to growth. (2) Eastern China has the highest AGTFP, while western China has the highest AGTFP growth rate. This result indicates that eastern China is a leader in green agricultural development, while green agricultural development in western China is the most promising. The “mid-China collapse” occurred in the central China agricultural area. The collapse of the central region was mainly caused by a decline in pure technical efficiency; more specifically, the pure technical efficiency of fertilizer severely restricted the sustainable agricultural development of this area. (3) The provinces that have great spatial differences in terms of agricultural development and the driving factors of AGTFP can develop suitable green agricultural evelopment strategies based on the results presented in this study.
(1)该模型将能源、CO2排放和农业非点源污染(NSP)纳入农业全要素绿色生产率的计算,能够更全面、更准确地衡量中国农业绿色全要素生产率(ATFP)。 (2)在静态层面上,论文模型是基于全局数据包络分析和加权罗素方向距离模型(WRDDM)构建的,用于计算中国的农业绿色综合生产率。在以前的研究中,中国的农业绿色全要素生产率还没有在国家、地区和省级层面上明确确定。该论文分别在国家、地区和省际水平上对农业生产率的特征和变化趋势进行了识别与分析。 (3)在动态层面上,论文应用卢恩伯格生产率指数(GLPI)从要素分解的角度来确定农业全要素生产率的变化,这在以前是没有研究过的。这种分解方法分别揭示了在投入利用、期望产出和污染控制方面的技术进步(TCH)、规模效率(SCH)和纯技术效率(PCH)情况,使我们能够确定农业绿色全要素生产率变化的主要来源。这一过程对确定提高中国农业绿色生产率机制有至关重要的作用。
