基于DEA模型的中国广电产业发展效率评价

The Evaluation of Development Efficiency of China's Radio, TV, Film Industry Based on DEA Model

运用DEA方法,对2007-2012年中国31个省级行政区及总局直属广电产业的效率值进行测算,对各地区广电产业的效率排名、效率发展趋势、规模报酬和差额变量进行分析,得出的主要结论如下：我国广电产业的整体技术效率相对无效,东部、中部和东北地区规模效率相对有效;2007-2012年,除了西部地区广电产业整体技术效率有所提高外,其他地区广电产业技术效率整体有所下降;我国广电产业的综合技术效率和纯技术效率呈现东、中、西依次递减的空间格局;东部、中部和东北地区的规模效率差异不明显,并远高于西部地区的规模效率;我国广电产业效率不足的原因主要来自于人员投入冗余。

By using the DEA model, the thesis analyzes the efficiency of China＇s radio, TV, film industry in 31 provinces and directly-controlled radio and TV administrations from 2007 to 2012,and evaluates the efficiency rankings, efficiency development trends, returns to scale and slack variable of the different regions. Through empirical research, the thesis gives some main conclusions. Firstly, the China＇s whole technique efficiency is relatively invalid. The scale efficiency is relatively valid in the east, the midland and the northeast. Secondly, the whole technique efficiency has decreased from 2007 to 2012 except in the west. Thirdly, the comprehensive technical efficiency and pure technical efficiency of China＇s radio and television industry has a decreasing spatial pattern of the east, the midland and the west. The differentiation of scale efficiency among the east, the midland and the northeast is not obvious, which is much higher than the west. Fourthly, the main cause of low efficiency is the redundant employment.
