The Empirical Research On TFP Of Tianjin Construction Industry Based On DEA-malmquist

Since China’s reform and opening up, with the rapid development of urbanization and economy, the construction industry of Tianjin has made rapid and brilliant progress. In the process of urbanization, the construction industry plays an important role. Problems appeared in the development are becoming more and more serious, even though the building has become a pillar industry of Tianjin’s economic development. There are many problems such as low management level, the waste of resources, low utilization rate of resources, which are not conducive to the improvement and healthy development of construction industry.The first two chapters are theoretical basis, the first chapter introduces the basic theory and research status of Total Factor Productivity, the second chapter introduces the basic theory and calculation method of DEA and DEA-malmquist model. In the third chapter, construction input and output indexes are selected using the method of Hierarchical Cluster and value added method, data sources and analyses of the basic characteristics of Tianjin construction industry data are given. The fourth chapter is the empirical analysis part of the article, so it is also the core part. Panel data during 2008-2012 of Tianjin construction industry is analyzed from the horizontal and longitudinal directions based on the model of DEA-malmquist. In the horizontal analysis, comparison and analysis about the TFP of construction industry is made between Tianjin and the rest of the 30 provinces, and TFPCH is broken into Technical change(TECH),Technical Efficiency change (EFFCH),Scale Efficiency change (SECH) and Pure Technology Efficiency change (PECH), then detailed analysis is given. In the longitudinal analysis, according to the enterprise type, Tianjin construction enterprises can be divided into State-owned enterprises, Collective-owned Enterprises, Hong Kong, Macao and Taiwan investment enterprises, Hong Kong, Macao and Taiwan owned enterprises, Foreign Investment Enterprises and wholly foreign-owned enterprises, comparison and analysis are made about the TFPCH, TECH, EFFCH, SECH and PECH of these 6 kinds of enterprises. Studies have shown that the TFP level of the Tianjin construction industry is not optimistic during these recent years. There is a big gap between Tianjin’TFPCH and the other provinces in recent years, the average TFPCH of Tianjin is only in the 23rd position, the PECH of Tianjin is very low, and the EFFCH of State-owned Enterprises and Collective-owned Enterprises have been in a state of stagnation in recent years. The last chapter summarizes the present situation of the Tianjin construction industry as well as the existing problems according to the empirical analysis result, and puts forward some opinions and suggestions for the development of the Tianjin construction industry.
