The Productivity Advancement and Its Factor Decomposition in Henan Province——A Comparison Analysis among the Municipal Data of DEA-Malmquist Index

With method of DEA Malmquist index analysis employed,the total factor productivity advancement and elements(in the years 2000-2009) of 18 cities in Henan Province are decomposed and analyzed.The results show that the cities' total factor productivity of Henan Province grows very strong,with annual rate of 14.7%.The less developed areas have the obvious trend of overtaking,but declining significantly in recent years.Further empirical analysis shows that technological progress is the main power to promote the growth of total factor productivity,but the decline of overall technical efficiency and pure technical efficiency is the bottleneck factor of restricting TFP ascension.Therefore,to restrain the momentum of total factor productivity decline,measures must be taken to vigorously promote technological progress,enhance the technical efficiency and scale efficiency.
