摘要
基于1994—2014年样本数据,运用脱钩指数、LMDI分解模型等方法,分析了山东省的农业化学化与农业经济增长的关系,并探讨了农业化学化的空间格局变化情况。结果表明:①农业化学化与农业经济增长的关系实现了从相对脱钩到绝对脱钩的转变;②效率效应、效益效应、规模效应对农业化学化投入物量的影响依次减弱,其中,效率效应可以减缓农业化学化投入物量的增加,效益效应是推动农业化学化投入物量增加的主要因素;③在空间格局变化方面,烟台、枣庄等地区的农业化学化程度高,潍坊、青岛、临沂等地区的农业化学化投入物量下降迅速。降低农业经济增长对农业对化学化的依赖,要从发展农业科技、加强低污染的农业现代化建设、提高农业生产组织化程度和推进农业结构调整上着手。
Based on the data during 1994 - 2014, using the method of decoupling index and LMDI decomposition model, this paper analyzed the relationship between agricultural chemical and agricultural economic growth in Shandong province, and discussed the chemical change of the spatial pattern of agriculture. The results show that the relationship between agricultural chemical and agricultural economic growth basically changed from relative decoupling to absolute decoupling, land pollution problems have increased; the remaining three effects lead to agricultural economy growth as follows： efficiency effect 〉 benefit effect 〉scale effect, and technical effect can reduce the increment amount of agricultural chemical inputs, while efficiency effect is the main factor of the increment amount of agricultural chemical inputs; Yantai andZaozhuang＇ s agricultural economic structure characteristic were clearly higher in agricultural chemical degree, while Weifang, Qingdao, Linyi had the higher degree of agricultural mechanization, irrigation and film usage, whose agricultural chemical inputs decreased rapidly. Reduced reliance on agricultural chemical, we should take efforts on the development of agricultural science and technology, the construction of the less pollution of agricultural modernization, the organization degree of agricultural production and the adjustment of agricultural structure.
