本文選題：農(nóng)業(yè)效率　切入點(diǎn)：廣西氣候變化　出處：《生態(tài)經(jīng)濟(jì)》2017年05期

【摘要】：基于廣西各地級(jí)市2006—2014年的面板數(shù)據(jù),運(yùn)用Malmquist-DEA方法測(cè)度廣西各地區(qū)的農(nóng)業(yè)生產(chǎn)效率并分析了其收斂情況,利用線性回歸的方法研究了氣候變化對(duì)廣西全區(qū)及5大經(jīng)濟(jì)區(qū)域農(nóng)業(yè)生產(chǎn)效率的影響。結(jié)果發(fā)現(xiàn):全區(qū)年際全要素生產(chǎn)率年均下降0.9%,但呈現(xiàn)出先下降后上升趨勢(shì);農(nóng)業(yè)生產(chǎn)效率存在收斂的趨勢(shì);總體上看,近年的氣候變化對(duì)農(nóng)業(yè)生產(chǎn)效率有負(fù)面影響。
[Abstract]:Based on the panel data of Guangxi prefectural cities from 2006 to 2014, the paper uses Malmquist-DEA method to measure the agricultural production efficiency in various regions of Guangxi and analyzes its convergence.The effects of climate change on the agricultural production efficiency of Guangxi and five economic regions were studied by linear regression method.The results showed that the annual annual total factor productivity of the whole region decreased 0.9 percent, but showed a trend of first decreasing and then rising; the agricultural production efficiency showed a convergent trend; in general, climate change had a negative impact on agricultural production efficiency in recent years.
