| In the recent 10 years, china's maize processing industry is developing fast; its development speed has even exceeded that of US. The fast development of china's maize processing industry has effectively stimulated the farmer's planting enthusiasm, which also promotes the development of china's maize production, it plays a positive role in guiding the restructuring of the agriculture, increasing the farmers' income, raising the agricultural production efficiency and promoting the provincial economic development. But, some problems also exist, for example, in some areas, the maize processing capacity is expanding too fast, the aimless and low level construction is serious, the efficiency of transformation and utilization after processing is low. If the government does not guide, not only the maize processing industry is hard to develop in the correct direction, it will also cause the problem in the total output and structure of grain (national development and reform commission, 2006), therefore, the development of china's maize processing industry urgently needs guidance of the government.The key to solve the existing problems in the maize processing industry in some areas at present is to adjust the industrial structure and raise the utilization rate of the maize processing. And the adjustments of the structure of the maize processing industry should be based and relied on the research of the competitiveness of maize processing industry, because we have to decide what is to develop, what is to stabilize and what is to compress according to the competitiveness in maize processing industry, so we should conduct the deep research to the domestic competitiveness in the sub-industry in the maize processing industry. Therefore, the final analysis of the restructuring of maize processing industry is to analyze its competitiveness, and the efficiency just embodies the competitiveness, as a result, it's necessary for us to analyze the efficiency before we study the competitiveness of maize processing industry. Through the analysis mentioned above, it is necessary to study the competitiveness of maize processing industry from the perspective of efficiency in order to restructure the maize processing industry, enhance its utilization efficiency, and promote its sustainable development.Jilin Province is china's important maize production base and it sends a lot of maize out. In recent years, Jilin Province's maize production, the volume of maize goods, exports, and send outs are all rank first in china. Moreover, Jilin Province's maize processing industry is developing very fast, the number of processing enterprises has reached more than 580 at the end of 2007, so we wonder if the problems that has existed in some areas such as the serious low level reestablishments, low efficiency after processing also exist in Jilin Province's maize processing industry? How are the competitiveness and its trend of Jilin Province's maize processing industry? This article try to judge the efficiency of the utilization and transformation after processing and its competitiveness through the test and analysis of the comparison of jilin province and other provinces' total factor productivity (TFP) (or simply call it "productivity"), technical efficiency (TE), the comparative advantage and the market competitiveness, and then select the superior industries in the maize processing industry according to the standard designed in this paper, analyze the factors influence the technical efficiency in maize processing industry through building Tobit model, putting forward suggestions for the improvement of processing efficiency, restructuring and competitiveness. The research in this paper will provide references to the government when they consider to constitute related industrial policies, promoting the improvement of the productive efficiency and competitiveness of maize processing industry, and promoting the optimization of agricultural structure and the sustainable development of the maize processing industry in Jilin Province.The paper takes the industrial competitiveness and the efficiency as the main research line, it combines the characteristics of maize processing industry and analyze the competitiveness and its influencing factors of maize processing industry taking the methods such as locational quotient (LQ), market share and econometric analysis based on the review of the theory in productivity and industry competitiveness, and at the same time the paper confirmed that TFP is one of the important factors that influence the maize processing industries' competitiveness; Therefore the paper used the data envelope analysis method (DEA) to test the changing situation of the increase of TFP, technical improvement and technical efficiency in the maize processing industry in jilin Province and its comparative province(e.g. liaoning shandong and hebei provinces). It also analyzes the factors that influence the improvement of the processing efficiency and then analyzes the level of technical efficiency and its influencing factors of maize processing industry. Finally, this paper put forward the research conclusions and suggestions in policies. The main research conclusions of this paper are as follows:(1) The maize processing industry in Jilin Province has a strong comparative advantage, but the maize processing industry's market competitiveness is comparatively low. Through the comparative analysis between jilin province and other provinces (e.g. liaoning shandong and hebei provinces) in terms of their comprehensive comparative advantage, when we consider the testing result of the average locational quotient of the overall maize processing industry during 1998 to 2005, we can find that the locational quotients of Jilin (2.08), Shandong (1.43), Hebei (1.05) are more than 1, and the locational quotient of Jilin province is the highest and the range of its increase is the also the highest, which indicates that the maize processing industry in jilin enjoys the strongest comparative advantage and enjoys the fastest developing speed. The testing result of the market competitiveness of maize processing industry shows that the total market share of the maize processing industry in jilin grows very fast during 1998 to 2005, but the average number (4%) only ranks third, which falls behind shandong(12.72%) and hebei (5.43%), it's only higher than liaoning (3.64%).(2) The total factor productivity (TFP) of the maize processing industry in Jilin Province is the important factor that influences the competitiveness of maize processing industry. We can find that they are remarkably related on 1% level through the related analysis between the competitiveness of maize processing industry and TFP. And the regression result of the influencing factors of jilin province's maize processing industry shows that TFP is remarkable on 1% level and passes the test.(3) The slow increase speed of technical efficiency affect the increase of TFP in the maize processing industry in Jilin Province. When we analyze the decomposition of the increase of the sub industries of the maize processing industry in jilin province, we can find that average rate of increase in TFP of starch and its products industry, feed processing industry, ethanol production industry and white liquor industry respectively are 31.6%, 13.5%, 29.9% and 9.7% during 8 years, and the average rate of increase in technological progress in 4 sub industries are respectively 29.2%, 10.1%, 17% and - 4%, while whose technological efficiency's average increase rate in 8 years are 1.8%, 3.1%, 11.1% and 10.2%, we can see that obviously the increase in the technological efficiency in three other sub industries are very slow except the white liquor manufacturing industry, as the technology progress constitutes the main factor that promotes the increase in TFP, the slow growth rate in technological efficiency affects the increase in TFP in the maize processing industry in jilin. (4) The technological efficiency in maize processing industry is Jilin Province is quite low, after the positive examination, the enterprise scale, capital density, industry concentration and the property right structure and so on are the influencing factors which influence the increase in the technical efficiency. This paper utilizes DEA two phases method, using the Tobit model to analyze to the influencing factors that influence the technical efficiency of maize processing industry in jilin province. the regression results show that the factors such as enterprise scale, capital density, industry concentration and property right structure are remarkable in the 10%, 5%, 1% and 5% level respectively, that is to say, they have positive and remarkable influence in the technical efficiency on different extent, especially industry concentration's influence is most remarkable.(5) The sub industries that enjoy comparative advantage in maize processing industry in Jilin Province are the starch and its products manufacturing industry and the ethanol manufacturing industry. This paper establish two criteria to define a industry which enjoys comparative advantage combined comparative advantage and competitiveness advantage:â‘ the localtional quotient should be more than 1 in a certain industry in a certain area. The greater the localtional quotient is, the stronger in the comparative advantage of an area.â‘¡the market share of a certain area should be higher than the national average level, that is 3.23%~2, the higher the market share is, the stronger of the comparative advantage in a certain area indicates. And according to the standard this paper establishes, the starch and its products manufacturing industry and the ethanol manufacturing industry are the two superior sub industries in the four sub industries in maize processing industry in jilin province.Based on the researching conclusions above, this paper puts forward three political suggestions briefly: First, take effective measures to enhance the TFP and technical efficiency in maize processing industry. Second, speed up scientific innovation and promote the technical progress in maize processing industry. Third, adjust the industrial structure of maize processing industry and maize planting industry.
