Efficiency, Technical Progress And Development Zones Productivity Growth

Base on the literature review of National Economic & Technological Development Areas (NETDAs), efficiency and the total factor productivity. This paper first summarizes the Development process and their achievements in economy development, then use of Data Envelopment Analysis (DEA) method to analyze the technical efficiency and total factor productivity of NETDAs. Thirdly, base on panel data regression, this paper attempt to illustrate factors which influence the efficiency progress, technological progress and total factor productivity progress, finally it is the conclusion review.Compared with their production frontier, the technical efficiency of most NETDAs is generally low and decreasing in recent years. Most NETDAs' relatively inefficiencies are because their low purely technical inefficiencies, others are because their low scale efficiencies. Generally speaking, NETDAs' scale efficiencies are high than the pure technical efficiencies. The paper also finds that, first batch of NETDAs has excellent performance than others in technical efficiency. And eastern NETDAs run more efficient than NETDAs in the central and western part.The total Factor Productivity (TFP) of NETDAs has rapid development in recent years. In 2002-2007, the average annual TFP of NETDAs is 8.22%. Research finds that the TFP growth is mainly due to technical progress. And the technical efficiency index is decreasing since 2002.Finally, the panel data regresses suggest that, FDI not only improve NETDAs' operational efficiency and technological progress, but also promote their total factor productivities. Technology also can promote technological progress and total factor productivity progress. Studies show that international trade has negative effect on NETDAs' technological progress and total factor productivity progress.
