摘要
利用DEA方法对2010年西部12省区市的建筑业生产效率进行了详细分析。结果显示,重庆、四川、陕西等7省区市建筑业DEA有效,而贵州、甘肃、青海、宁夏均处于规模递增阶段,云南和青海两省则存在较大的投入冗余和产出不足。进一步分析青海省的生产效率增长情况,发现其增长速度起伏较大,且增长仅来自于技术进步,未能实现规模经济。云南和青海两省应从结构调整、技术改造及资产优化配置和有效利用等方面实现技术效率和规模效率的提高,最终提升建筑业的整体生产效率。
The paper conducted a detailed analysis of production efficiency of construction industry by DEA method in twelve western provinces in 2010.The results show that seven provinces including Chongqing,Sichuan and Shanxi are DEA efficient in the construction;Guizhou,Gansu,Qinghai and Ningxia are in a stage of increasing scale;Yunnan and Qinghai has serious redundancy inputs and insufficiency outputs.Further analysis of the productivity growth of Qinghai Province,we found that its growth rate fluctuated considerably,only coming from technological progress and leading to failure to achieve economies of scale.Finally,we argue that Yunnan and Qinghai should achieve technical and scale efficiency by restructuring,transformation,optimal allocation and effective utilization of asset,and finally,upgrade the overall productivity of the construction.
