摘要
采用超效率 SBM-GML模型对 1990-2020 年中国 31 个省份的农业绿色全要素生产率及其变化指数进行测算,通过农业产值增长率和绿色全要素生产率效率值将不同省份划分成四个区域,运用面板固定效应模型探究农业生产用能对农业经济增长的影响和区域异质性,应用面板门槛模型对农业经济增长与农业能源碳排放的关系进行分析.研究表明:(1)1990-2020 年中国的绿色全要素生产率呈现缓慢上升趋势,其中技术进步是主要推动力,而技术效率指数增速为负.(2)全国及各区域农业生产用能与农业产出的相关系数均为正值,即生产用能的投入能够明显增加农业产出,但是产出增加的实现程度存在区域异质性.(3)我国农业经济增长和农业能源碳排放之间存在单一门槛效应,在门槛值前,二者正向关系较强;跨过门槛值后,二者正向关系减弱,呈现协调发展态势.据此,提出积极鼓励农业技术进步、全面提高农业技术效率、因地制宜优化农业生产用能结构、差异化选择农业绿色发展道路等政策建议.
Abstract
This paper uses the super-efficiency SBM-GML model to measure the agricultural green total factor productivity and its change index of 31 provinces in China from 1990 to 2020.According to the growth rate of agricultural output value and the efficiency value of green total factor productivity,different provinces were divided into four regions.The panel fixed effect model was used to explore the influence of agricultural production energy on agricultural economic growth and regional heterogeneity,and the panel threshold model was used to analyze the relationship between agricultural economic growth and agricultural energy carbon emissions.The results show that:(1)From 1990 to 2020,China's green total factor productivity shows a slow rising trend,in which technological progress is the main driving force,while the growth rate of technical efficiency index is negative.(2)The correlation coefficients between agricultural production energy use and agricultural output are all positive nationwide and in all regions,that is,the input of production energy use can significantly increase agricultural output,but the degree of realization of output increase displays regional heterogeneity.(3)There is a single threshold effect between China's agricultural economic growth and agricultural energy carbon emissions,and the positive relationship between the two is strong before the threshold value;After crossing the threshold value,the positive relationship between the two is weakened and the two show a coordinated development trend.Based on this,the paper puts forward some policy suggestions,such as actively encouraging the progress of agricultural technology,comprehensively improving the level of agricultural technical efficiency,optimizing the energy use structure of agricultural production according to local conditions,and differentiating the choice of agricultural green development path.
