Total Factor Productivity and its Spatial Variation in Jiangsu from 1993 to 2009
利用1990-2006年江苏省65个县市的数据，测量了技术效率并分解了全要素生产率增长，分析了其与经济增长的关系，发现苏南技术效率最高、苏北最低，城市化率和产业结构是效率提升的关键，而政府干预则有负面影响。
Total factor productivity is a basic index reflecting the quality of economic growth and the rate of technical progress in a country or a region.Empirical study is conducted to test Jiangsu's counties datasets(1990-2006),using a translog production frontier specification with heterogeneous technical efficiency explained by exogenous variables.This paper measures technical efficiency between 65 counties(cities) of Jiangsu and decomposes the growth rate of TFP(Total Factor Productivity) to technical efficiency,technology progress and scale economic.This paper analyzes the relationship between TFP and economic growth,then classifies the economic growth patterns of 65 counties(cities) into four categories according to the speed of TFP and economic growth,and finally discusses the spatial divergence of TFPs and economic growth rates among 65 counties(cities).The findings of this study show:(1) Southern Jiangsu technical efficiency was the highest,technical efficiency of Northern Jiangsu was the lowest.Southern smallest decrease and northern had the largest decline.Within the Southern areas technical efficiency was more balanced,while within the middle and northern areas there was a differentiation.(2)Urbanization rate,the proportion of secondary industry in GDP,the ratio of exports and GDP are important factors for efficiency improvement,but government intervention are harmful to efficiency.(3)Regional growth rate of total factor productivity was increased;TFP growth of the southern Jiangsu was steady,while the variation of TFP in the middle and northern Jiangsu was big.TFP growth was mainly due to technology progress.Technical efficiency of southern Jiangsu to TFP growth with minimal impact,technical efficiency change of northern Jiangsu made great impact on TFP growth rate which contribution rate was-188.66%.(4)1993-2002,total factor productivity growth was not related with the level of economic development,the region with low level of economic also had higher TFP growth.
