基于DEA模型的省域服务业投入产出效率评价

Evaluation on China′s provincial input-output efficiency in service industry based on DEA model

为进一步了解服务业投入产出效率低下问题,应用三阶段DEA方法对我国31省份及东中西部2014年服务业投入产出效率进行评价.研究表明,我国各省份服务业投入产出效率差异较大,大部分省份的服务业处于规模报酬递增阶段,其服务业效率有待提高,且服务业效率受城镇化水平、第三产业所占比重、政府支出、人均可支配收入等环境因素影响较大;我国东部地区服务业效率最高,中部次之,西部最低;东西部服务业效率受环境因素影响相对较大,中部次之.

Three-stage DEA model is used to analyze input-output efficiency service industry in China＇s 31 provinces and the east-central-west regions in 2014,in hopes of finding the problems of low efficiency. Research shows that there is a bigger difference in the service industry input- output efficiency in China,and the majority of provinces are in the stage of increasing returns to scale. So the efficiency of service industry needs to be improved, and it is affected by the town level, the proportion of the third industry, government expenditure, per capital disposable in-come and other environment factors. The highest efficiency of service industry is the east, and then the central, the lowest the west. East and west service efficiency is largely influenced by environmental factors, and then is the Central.
