Abstract:
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.
