我国农药使用强度的演进特征与省际收敛——基于1991-2014年省级面板数据的分析
Evolution characteristics and provincial convergence of pesticide application density in China: An empirical study based on the provincial data from 1991 to 2014
摘要
Abstract
Promoting the reduction and scientific application of pesticide is an internal requirement of safeguarding the safety of agricultural production, agricultural product quality and ecological environment, and realizing the sustainable development of agriculture. This paper analyzed the evolution characteristics of pesticide application density in China from 1991 to 2014, and then tested the provincial convergence of the whole nation, eastern region, central region and western region respectively. Results show that: there was a remarkable increase in pesticide application density of both national and provincial levels, and the pesticide application intensities of eastern provinces, central provinces, and western provinces was decreasing in general in the above order. The absolute gaps with the highest and the lowest pesticide application densities between provinces of the three regions were further expanded, and the absolute gaps of eastern provinces were remarkably higher than that of central provinces and western provinces. The provincial absoluteσ convergence trend was not consistent in national level and regional level. The absolute gap of pesticide application density was not significantly reduced in the nation in general and in western provinces, but significantly was reduced in central provinces and even significantly expanded in eastern provinces. The provincial absoluteβ convergence and conditionalβ convergence trends were consistent in both national and regional levels. In addition, the pesticide application densities of provinces with relative lower density in initial stage and the provinces which further away from their steady-state values have faster growth speed. Compared with eastern provinces and western provinces, the converging speed of pesticide application density of central provinces was faster. Finally, this paper provides the following policy recommendations to scientifically and effectively control pesticide applications: to carry out regionally comprehensive prevention and treatment, to implement sustainable prevention and control, and to strengthen monitoring and early warning systems.关键词
