| The financial crisis has a great impact on China’s financial system also to China’s manufacturing industry. Europe and the United States recognize harm of "de-industrialization", instead of "back to the time of manufacturing". The plan of four trillion investment stimulated directly on the upper reaches of China’s manufacturing industry, especially iron and steel, building materials, construction machinery and other industries, but also resulted in the excessive investment problem. In recent years, export hindered, labor shortage, cost up and other unfavorable factors also plagued China’s manufacturing industry. Because of the unbalanced development of regional economy in China, local and provincial differences larger manufacturing output.Based on summarizing efficiency theory and model, according to the different environment and the limitations of DEA method, this paper selects three-stage DEA model to estimate the efficiency of China’s regional manufacturing industry. Through the second stage Tobit model to eliminate the effect of environment variables and stochastic error, to obtain a more accurate result efficiency output. This paper selects the data of30provinces from2008to2011and uses the manufacturing industry total output value, total profit as the output index, number of employees, manufacturing of depreciation of fixed assets as input indicators, select GDP, exports, technology, wages as environment variables.The empirical study shows that:in our country, the capital investment margin of many provinces manufacturing is large, labor input with no margin, which means our country exists the problem of excessive investment, also confirmed the labor shortage exists from the side. GDP and input slacks have positive relationship, that the more economically developed provinces invest too much is more significant. Technology, export and investment margin into a negative relationship, which could promote manufacturing efficiency. Wages and input slacks a negative relationship, that the wage increase negative effect of the rising cost of weak positive effect on technology innovation, wages are conducive to promoting the efficiency of manufacturing progress. The existence of environmental factors makes one stage DEA efficiency values below three stage efficiency value. The eastern region is lower than the efficiency of the central and western regions, resulting in too much margin in the production process. Industry transfer is the effective way to improve the efficiency of China’s manufacturing industry. Manufacturing industry of most provinces is at the decreasing stage of the scale return. Upgrading of structure is an urgent need for manufacturing industry. |
