摘要
以淮河生态经济带为研究对象,运用SBM模型和Malmquist指数模型对2011—2020年淮河生态经济带五省28市的农业绿色发展效率进行测算,并借助泰尔指数分析其空间差异和布局特点,利用Tobit模型探讨淮河生态经济带农业绿色发展效率的影响因素。结果表明:淮河生态经济带农业绿色发展效率近十年间逐年递增,2017年增幅最大,其中孝感市农业绿色发展效率常居首位;淮河生态经济带东部、北部和中西部农业绿色发展效率总体差异以波动式缓慢拉大,总体泰尔指数峰值出现在2018年;城镇化水平和化肥使用效率因素均产生推动效应,而土地过度规模化则起到阻碍作用。基于研究结论提出相应政策建议,为淮河生态经济带农业绿色发展提供参考。
Taking the Huaihe River Economic Belt as the research object,this paper calculated the agricultural green development efficiency of 28 cities in the Huaihe River Economic Belt from 2011 to 2020 by using SBM model and Malmquist index model,and analyzed its spatial differences and layout characteristics with the help of Theil index and ArcGIS software;finally,the paper used Tobit model to discuss the influencing factors of agricultural green development efficiency in Huaihe River Economic Belt.The results show that:the agricultural green development efficiency of the Huaihe River Economic Belt has increased year by year in the past decade,with the largest increase in 2017;among them,the agricultural green development efficiency of Xiaogan City often ranks the first among the 28 prefecture-level cities.The overall difference of agricultural green development efficiency in the eastern,northern,central and western regions of the Huaihe River Economic Belt is slowly enlarged by waves,and the peak of Theil index appears in 2018.The level of urbanization and the efficiency of chemical fertilizer use will promote the efficiency of agricultural green development,while the excessive scale of land will hinder it.Based on the research conclusions,the corresponding policy recommendations are put forward in order to provide reference for the green development of agriculture in the Huaihe River Economic Belt.
