A Study on Specialization,Technological Efficiency Improvement & Technical Progress:An Empirical Analysis on China′ Pesticide Manufacturing Industry

For the purpose of inquiring into the relationship between the specialization level and productivity of our agricultural chemical manufacturing,this paper uses location quotient to measure the level of specialization,and uses Malmquist index of DEA to measure the total factor productivity,technique efficiency and technology change in our agricultural chemical manufacturing and uses the regression analysis to empirically analyzes the effect of the factors such as specialization level on the growth of Total Factor Productivity(TFP).The results show that the specialization is beneficial to the total factor productivity through the efficiency improvement,technical progress and TFP growth;TFP of agricultural chemical manufacturing increases greatly in the regions with small-sized regional enterprises,and small-sized regional enterprise is beneficial to the technical efficiency improvement but not to the technical progress.The capital density has a positive impact on both the TFP growth and technical efficiency improvement.FDI is conducive to the technical efficiency improvement,but not to the industrial technical progress.The proportion of state-owned assets has no obvious effect on the TFP growth,technical progress and technical efficiency improvement.
