广西种植业生产要素优化路径研究

Research on Optimal Path of Crop Production Factors in Guangxi

基于三阶段DEA模型测度了2011~2016年广西种植业生产效率,并对2016年广西种植业生产要素冗余状况及其优化空间进行了初步探究。研究表明:环境因素和统计噪声对种植业生产效率存在明显影响,剔除二者后,2011~2016年广西种植业生产效率有所降低,生产效率损失的主要因素由纯技术效率非有效转变为规模效率非有效。在环境因素中,城镇化率上升是广西种植业生产效率改善的有利因素,财政支农比重增加、农民人均收入增长均未对广西种植业生产效率产生有利影响。广西各地区种植业生产要素冗余程度各有差异,需根据地区实际情况进行优化。发展适度的规模化经营、提升财政支农资金效率、转变农民粗放经营理念、实行区域差别化生产要素调控政策是提高广西种植业生产效率的可行途径。

The production efficiency of Guangxi’s planting industry from 2011 to 2016 was measured on the basis of the three-phase DEA model to analyze the redundancy status of production factors and the optimization space in Guangxi planting industry of 2016. The results show: Environmental factors and statistical noise have a significant impact on crop production efficiency, without which, the production efficiency of Guangxi’s planting industry decreased from 2011 to 2016, and the main factor for the loss of production efficiency changed from the inefficiency of pure technical efficiency to scale efficiency. The degree of redundancy of crop production factors varies in different regions of Guangxi, which needs to be optimized according to the actual situation of the region. The local community should develop moderately scaled operations and increase the productivity of planting industry;improve the funding efficiency of financial support for agriculture and change farmers’ extensive management concept;and differentially regulate and control different regions based on the disparity in the redundancy of production factors.
