吉林省经济效率差异及空间格局演变

利用数据包络分析（DEA）方法对吉林省2003~2013年经济效率差异和空间格局演变进行了深入研究。研究结果显示：吉林省经济发展总体效率相对较高,纯技术效率值较为稳定,规模效率值波动上升,处于规模收益持续递增阶段,规模效率始终是影响综合效率的主要原因;中部地区的综合效率水平高于东部和西部;在分解效率方面,与综合效率大致相同,中部地区的纯技术效率和规模效率均高于东部和西部;受区域经济发展不平衡影响,不同城市投入的资源水平存在差异,综合效率,纯技术效率和规模效率均呈现出由中部地区向东、西部扩张的空间格局。不同城市类型、城市规模对吉林省经济效率演变具有十分重要的影响;区域经济政策、市场经济、工业基础和产业集聚、科技水平等驱动力共同作用于吉林省经济效率空间格局的演化。

The Inequality of Economic Efficiency and Space Pattern Evolution in Jilin Province

As a typical example of old industrial bases and major grain producing areas, Jilin Province is playing an important role in economic development and food security in China. However, because of relying on extensive mode of growth with high pollution and high energy consumption in a long period, it was paid more attention to output of production and overlooking the promotion of economic efficiency in Jilin Province. To improve the economic efficiency and to make the industrial structure realize the transformation and upgrade are urgent. It is an emergency to improve economic efficiency under the circumstances of economic "new normal". An analysis of economic efficiency difference and spatial pattern evolution in Jilin Province from 2003-2012 is carried by means of DEA. The results show that the total efficiency of economic development is relatively high in Jilin Province, the technical efficiency relatively is stable, the scale efficiency wavelike rises, and in the stage of progressive increase of scale return, the overall efficiency is always influenced by scale efficiency. The overall efficiency level in the central Jilin is higher than eastern and western Jilin. The overall efficiency presents differences among eastern, central and western Jilin, and the difference is mainly the big gap between central and western Jilin. The same as overall efficiency, the technical efficiency and scale efficiency of central Jilin is higher than eastern and western Jilin. The devoted resources level in different cities exist differences because of the unbalanced economic development, the overall efficiency, technical efficiency and scale efficiency. The city size has great influence on the economic efficiency evolution in Jilin Province. The result of quantitative analysis shows that secondary industry, the tertiary industry, transportation, reform of state-owned enterprises and high educators play an important role in the promotion of economic efficiency in Jilin Province; Regional economic policy, market economy, industry base and industrial agglomeration, level of science and technology impact on the spatial pattern evolution of economic efficiency in Jilin Province. The difference of economic efficiency is the foundation to make the regional division come to realize.
