【摘要】：玉米是极具重要战略意义的粮食作物。为破解我国玉米生产面临的资源环境约束日趋严峻等困境,该文研究机械化这一现代化生产手段对我国玉米产业竞争力的影响,旨在提升玉米生产水平,促进玉米产业健康发展,提高产业竞争力。该文以竞争力、产业竞争力以及农业机械化等相关理论为研究基础。运用SWOT分析法,得到我国玉米产业目前劣势突出,机遇与挑战并存,产业未来的发展战略应该优先选择WO策略同时兼顾WT策略。基于因素分析法构建了我国玉米产业国际与国内竞争力分析指标体系。运用主成分分析法,实证得出世界十大玉米生产国中我国玉米产业的国际竞争力弱且呈波动特性。运用偏最小二乘法分析对11个影响我国玉米产业国际竞争力的因素的重要性进行了排序。基于DEA模型分析得到:玉米生产效率的改善程度与种植效益在三大粮食作物中均低;我国玉米生产效率整体偏低,综合技术效率、纯技术效率和规模效率均有较大提升空间,其提升显著依赖技术进步;目前玉米生产各要素配置不合理。基于ESDA空间分析得到我国玉米生产整体没有形成空间“H-H”集聚类型;玉米综合生产技术效率较高的省(区),其纯技术效率与规模效率均较高,而综合效率较低的省(区),纯技术效率与规模效率的差异较大。运用回归分析得到我国玉米生产效率与其6个影响因素的相关性。论文还构建了“玉米机械化生产—玉米产业竞争力”的耦合系统与系统综合评价体系,实证表明玉米机械化生产子系统与玉米产业竞争力子系统之间呈高度协调耦合状态,二者相互促进。同时该文分析了机械化生产如何通过作用于我国玉米产业的主要影响因素进而有效促进我国玉米产业国内竞争力实现提升;探究了我国玉米机械化生产水平提升的需求与路径;并提出了现阶段提升玉米机械化生产水平的6条路径。
[Abstract]:Maize is a grain crop of very important strategic significance. In order to solve the difficulties such as the increasingly severe resource and environmental constraints faced by maize production in China, this paper studies the influence of mechanization, a modern production means, on the competitiveness of maize industry in China. The purpose of this paper is to improve the level of maize production, promote the healthy development of maize industry, and improve the competitiveness of the industry. Based on the relevant theories of competitiveness, industrial competitiveness and agricultural mechanization, this paper applies SWOT analysis method. The corn industry in China has outstanding disadvantages at present, opportunities and challenges exist side by side. WO strategy and WT strategy should be selected first in the future development strategy of industry. Based on factor analysis method, the index system of international and domestic competitiveness analysis of maize industry in China is constructed. Empirical results show that the international competitiveness of China's corn industry is weak and fluctuating among the top ten corn producing countries in the world. The importance of 11 factors affecting the international competitiveness of China's corn industry is analyzed by partial least square method. Based on the analysis of DEA model, it was concluded that the improvement degree and planting benefit of maize production efficiency were all low in the three grain crops; The overall efficiency of maize production in China is on the low side, and the comprehensive technical efficiency, pure technical efficiency and scale efficiency have great room for improvement, and the improvement of maize production efficiency depends significantly on technological progress. Based on the ESDA spatial analysis, it is concluded that there is no spatial "H-H" agglomeration type in the whole maize production in China, and the pure technical efficiency and scale efficiency are higher in the provinces (regions) with higher technical efficiency of corn comprehensive production. But in the province with low comprehensive efficiency, the difference between pure technical efficiency and scale efficiency is great. The correlation between maize production efficiency and its six influencing factors in China is obtained by regression analysis. The "Maize Mechanization" is also constructed in this paper. Coupling system and system Comprehensive Evaluation system of Production-Corn Industry Competitiveness, The empirical results show that there is a highly coordinated coupling between maize mechanization production subsystem and maize industry competitiveness subsystem. At the same time, the paper analyzes how mechanized production can effectively promote the domestic competitiveness of China's corn industry by influencing the main factors of maize industry in China. This paper probes into the demand and path of improving the production level of maize mechanization in China, and puts forward six ways to improve the production level of maize mechanization at the present stage.
