| 摘 要： | 基于DEA模型中的生产规模报酬可变(VRS)子模型BC2,以能源富集区陕西省榆林市为例,对其2013年经济发展的综合效率、技术效率及规模效率进行测度。研究结果表明:(1)总体而言,榆林市经济发展效率在地理空间上呈南北发展效率高、中部发展效率低的分布特征,并存在南北"DEA有效"的双中心结构;(2)经济发展的规模效率是榆林市经济发展综合效率的主要制约因素;(3)榆阳区、府谷县、横山县、米脂县存在生产要素投入冗余现象,以横山县最为突出。可通过提高劳动者的素质、改善投资环境、促进产业结构高级化及专业化、提高综合能源的利用效率等来提高各区县的经济发展效率。

| Abstract: | To improve the efficiency of economic development is the important measure of sound and rapid e -conomic development of Yulin City .The sub model BC 2 based on DEA model are used to measure comprehensive efficiency, technical efficiency and scale efficiency of the economic development of Yulin City in 2013.The eco-nomic development efficiency of Yulin presents high development efficiency in north and south but low development efficiency in the middle of the city .There exists a double center structure of “DEA efficient” in north and south . The scale efficiency of economic development is the main aspects of restraining comprehensive efficiency of Yulin City.In the whole city,there exists fillers of factors of production in Yuyang District , Fugu County, Hengshan County and Mizhi County , especially in Hengshan County .Research suggests that improving the quality of the work-ers and the investment environment , optimizing the structure of domestic trade reasonably , promoting industrial structure upgrading and specialization , improving the efficient use of comprehensive energy are the countermeasures of raising the efficiency of economic development of districts and counties . |
