黑龙江省粮食生产技术效率研究

Study on Grain Production Efficiency in Heilongjiang Province

为明确黑龙江省粮食生产的技术效率水平及影响因素,本研究综合运用了数据包络分析方法和随机前沿分析方法,通过三阶段DEA分析模型,利用经济环境、自然环境和社会环境的相关变量对农业生产中的人力、机械、土地等投入变量进行了修正,对黑龙江省与我国其他地区粮食综合技术效率进行比较分析。结果表明:环境因素对各地区的农业生产投入起到了较为显著的影响,在剔除环境因素影响下,大部分地区的计算结果发生了变化。黑龙江省粮食生产综合技术效率虽然处于我国农业生产的前沿水平,但超效率分析结果表明黑龙江省粮食生产技术仍具备一定的提升空间。

In order to clarifly the technical efficiency level and influencing factors of grain production in Heilongjiang Province,the data envelopment analysis method and the random frontier analysis method were used comprehensively.Through the Three-stage DEA analysis model,the input variables of human force,machinery,land and other inputs in agricultural production were modified by using the relevant variables of economic environment,natural environment and social environment.From the macro perspective,modified the comprehensive technical efficiency of grain between Heilongjiang Province and other regions were compared and analyzed.The results showed that the environmental factors had a significant impact on the agricultural production investment in various regions,and the calculation results in most regions had changed after excluding the environmental factors.Although the comprehensive technical efficiency of grain production in Heilongjiang Province was at the forefront of China′s agricultural production,the results of super efficiency analysis showed that Heilongjiang Province still had some room to improve.
