摘  要:将农业碳汇与碳排放分别视为期望与非期望产出引人到农业生产绩效分析框架,以2007-2020年全国31个省(自治区、直辖市)面板数据为样本,运用碳计量等模型评估农业生产碳汇效应与农业生产绩效,并揭示其时空特征。研究结果表明:①我国净碳汇量均为正值,农业生态效应较好。②我国农业生产效率呈先减后增的波动变化趋势,总体虽逐渐改善,但增幅不明显,发展形势不容乐观;农业技术进步不断创新,增长效应良好;农业技术效率增长稳定,追赶效应强劲;内蒙古、广西的技术进步指数偏低,负向抵消了技术效率改进带来的追赶效应;其余地区是由技术进步引起的增长效应和技术效率引起的追赶效应共同促进。③农业生产空间联结格局稳定,但受距离衰减规律约束,东北与经济发达地区空间联系较强,而中西部地区联系出现脱节现象,上海、江苏和浙江成为增长极。④大量省域处于低效率一低福利区域,面临着满足人们基本发展需求与碳排放局限的双重挑战。Agriculture is not only an important source of greenhouse gas emissions,but also a huge carbon sink system.Based on the joint production theory,this paper introduces agricultural carbon sink and carbon emission as expected and unexpected output respectively into the agricultural economic analysis framework,and uses the panel data of 31 provinces in China from 2007 to 2020 to measure the carbon sinks and evaluate the spatio-temporal of agricultural production by the means of the super efficiency SBM,Malmquist-Luenberger(ML)index,Spatial Gravity model. The results show that: 1)China’s net carbon sinks are all positive,and the agricultural ecological effect is good. 2)The production performance of agriculture in China shows a fluctuating trend which is decrease at the early stage and then increase. Although it is getting better,the growth rate is not obvious and the development form is not optimistic.China’s agricultural technology progress has been innovating continuously,and the growth effect is good. The agricultural technology efficiency growth is stable and the catch-up effect is strong. The low technological progress index represented by Inner Mongolia and Guangxi offsets the catch-up effect brought by the improvement of technical efficiency. In other regions,the growth effect caused by technological progress and the catch-up effect caused by technical efficiency jointly promote. 3) The spatial connection pattern of agricultural production is stable, but restricted by the law of distance attenuation, the spatial connection between northeastern China and economically developed areas is strong,while the connection between central and western regions is out of touch. Shanghai, Jiangsu and Zhejiang become new growth poles. 4) A large number of provinces are in low efficiency and low welfare areas,facing the dual challenges of meeting people’s basic development needs and carbon emission limitations.
