【摘要】：科学测度农业碳生产率并探究其空间关联状况是构建兼具差异化和协调性的碳减排政策的基石。本文对2001-2012年中国31个省(市、区)的农业碳生产率进行测度,在此基础上利用空间相关性指数对其空间相关性、聚类状况进行考察,并运用空间杜宾模型分析农业碳生产率变动的主要影响因素及空间效应。结果表明:12001-2012年中国各省区农业碳生产率均呈现较为明显的提升趋势,除个别省域外,省域农业碳生产率与其所属地区的经济发展程度基本一致;与此同时,农业碳生产率区域间"异质化"与区域内"均质化"的趋势显现,且以地区间农业碳生产率的"分化"与"极化"的现象较为严重;2省域农业碳生产率存在着较强的空间自相关性,各省区农业产业结构对本地区农业碳生产率具有负向影响,农村教育水平和农业开放程度对其具有正向影响,而农业经济发展水平、受灾程度和农业公共投资对其影响不甚明显;此外,省域农业碳生产率在空间上存在较为明显的溢出效应,其中一省区农村教育水平和农业开放水平对邻域农业碳生产率的提高具有正向带动作用,农业经济发展水平对其则起到抑制作用,而农业产业结构、自然灾害和农业公共投资对周边地区农业碳生产率的影响并不明显。
[Abstract]:The scientific measurement of agricultural carbon productivity and explore the spatial correlation condition is the basis for constructing both the difference and coordination of carbon emission reduction policies. In 2001-2012 years Chinese 31 provinces (cities, districts) of the agricultural carbon productivity measure, based on the spatial correlation index of the spatial correlation of clustering, and using the spatial Durbin model to analyze the main influence factors of the changes of agricultural carbon productivity and spatial effect. The results showed that: 12001-2012 years of agricultural carbon productivity Chinese provinces showed ascending trend more obvious, in addition to the individual province outside the provincial agricultural carbon productivity and the level of economic development in the area are basically the same; at the same time, the regional agricultural carbon productivity between "heterogeneity" and regional "homogenization" trend appeared, and the regional agricultural carbon productivity "differentiation" and "polarization" phenomenon is serious; 2 The domain of agricultural carbon productivity has strong spatial autocorrelation, regional agricultural industrial structure has a negative impact on the productivity of local agricultural carbon, rural education level and agricultural openness has a positive impact on the agricultural economic development level, affected the degree and the public investment in agriculture is not very obvious; in addition, there is an overflow the more obvious effects of the provincial agricultural carbon productivity in the space, which has a positive effect to improve the level of rural education and agricultural provinces open neighborhood of carbon productivity level on agriculture and agricultural economic development level of the play inhibitory effect, and the industrial structure of agriculture, natural disasters and the impact of public investment on agricultural productivity of agricultural carbon surrounding the area is not obvious.
