基于DEA分析的辽宁省建筑业生产效率评价研究

Research on Production Efficiency Evaluation of Construction Industry in Liaoning Province Based on DEA Analysis

采用辽宁省2015年的面板数据,运用DEA分析法的C2R模型和BC2模型,从综合效率、技术效率以及规模效率3个方面对辽宁省14个城市建筑业效率进行了分析评价。结果显示:抚顺、本溪、阜新3个城市存在产出不足情况;抚顺、本溪、锦州等7个城市存在投入冗余情况,特别是建筑业从业人数投入冗余尤为严重。指出要合理减少DEA无效的城市的从业人数和总资产投入并提高投入资源的利用效率,以提高辽宁省建筑业整体生产效率,促进辽宁省建筑业健康发展。

Based on the panel data of Liaoning Province in 2015,this paper analyzes and evaluates the efficiency of 14 cities of Liaoning Province by using the C2 R model and BC2 model of DEA analysis method from the three aspects： comprehensive efficiency,technical efficiency and scale efficiency. The results showthat three cities such as Fushun,Benxi and Fuxin are insufficient outputs.There are 7 cities including Fushun,Benxi,Jinzhou,etc,which have invested in redundant situation. Particulary,the number of redundant inputs of the construction industry is particularly serious.The paper reasonably proposes invalid urban number of employees of DEA,total asset investment and improves utilization efficiency of input resources in order to improve overall production efficiency in construction industry of Liaoning province and promote healthy development of construction industry in Liaoning province.
