本文选取进入壁垒、市场主体构成、利润率、规模经济、产能利用率、研发创新能力和全要素生产率等对2008-2014年我国粮食加工业的市场结构变动与产业发展绩效进行研究,并通过相关系数分析粮食加工业市场结构与产业发展绩效之间的关系.结果表明:1)在改革和外资进入背景下,进入壁垒经历了从降低到提高的演变过程.国有企业和外资企业的市场份额趋于下降,民营企业的市场份额逐渐上升;2)中国粮食加工业发展绩效正逐步改善,但是整体水平偏低;3)粮食加工业市场结构的优化改善了产业发展绩效,同时也产生了一定的负面影响.在此基础上,提出了继续推进粮食加工业市场化改革;促进国内粮食企业整合重组;加大规模性粮食企业创新研发的建议.%Based on the data from 2008 to 2014, and applying the concepts of the barriers to entry, the market main body composition, the profit ratio, the economy of scale, the capacity utilization rate, the R&D innovation ability, the total factor productivity, and the correlation coefficient, this paper analyzed the market structure change and the industry development performance of China's grain processing industry and their relationship. Results show that: 1) under the background of market-oriented reform and foreign capital's entry, the barriers to entry have experienced a change from decreasing to increasing. The market share of state owned enterprises and foreign-invested enterprises tended to decline while the market share of private enterprises increased gradually; 2) although the industry development performance of China's grain processing industry was improving gradually, the overall level was low; and 3) the optimization of the market structure has improved the industry development performance of the grain processing industry and imposed some negative effects at the same time. Based on above analysis results, this paper provides the following suggestions: continuing to promote market-oriented reform of the grain processing industry, promoting the integration and reorganization of China's grain processing industry, and increasing large-scale grain enterprises' innovation and R&D.
