Calculation and Analysis of the China's Provincial Food Manufacturing Operating Efficiency Based on Data Envelopment Analysis(DEA)

Based on six years of the statistical data from 2002 to 2007,and using the data envelopment analysis(DEA) comprehensively evaluates the technical efficiency of China's provincial food manufacturing management and has a regional comparison analysis.The results are as follows the fluctuating trend of the average technical efficiency value shows that our food manufacturing management level is not very stable;the accordance of the changing trend of technology efficiency with the pure technical efficiency show that our food manufacturing technology efficiency is largely influenced by food manufacturing pure technical efficiency effects;in the efficient scale,the food manufacturing generally present stable or diminishing returns to scale in the eastern region.According to the trend of Central and West,due to its food manufacturing is still in its infancy,their production and business operation are in the stage of increasing returns to scale.Expanding the scope of operation,will be able to achieve the utility that the economies of scale bring to them,the northeast region's food manufacturing is mostly in the stable returns to scale.It shows that the current food manufacturing should moderately enlarge the operation scale on the basis of the stable situation.
