中国粮食—生态效率的空间分布与差异性研究
Spatio-temporal dynamic distribution and regional differences of grain-ecological efficiency in China
摘要
Abstract
China's grain production has been facing the double pressure of ecological environment and natural resources for a long time.Optimizing the ecological efficiency of grain production is of great significance to reduce the environmental burden and achieve sustainable development.From the perspective of space,Super-SBM,coefficient of variation,Dagum Gini coefficient and Markov chain transfer matrix were comprehensively used to investigate the spatial and temporal distribution characteristics and regional differences of grain-eco-efficiency in 31 provinces of China from 2005 to 2021.The results showed that:① The fluctuation of grain-eco-effi-ciency in China had obvious characteristics,and there was no convergence in other years except 2007,2013 and 2019.② The overall re-gional difference of grain-eco-efficiency was increasing,and the source of the difference was from super-variable density and inter-regional difference.③ According to the transfer probability of grain-eco-efficiency in the whole country and each region,the trans-fer probability of grain-eco-efficiency in the whole country was the largest,followed by the transfer probability among the same level;The pattern and level of grain-eco-efficiency development in different regions tended to be the same,which forms the"club effect".④ From 2022 to 2031,the national grain-eco-efficiency growth rate was slow,and the regional differences gradually decreased,but there were still large differences.关键词
