Study Of Chinese Manufacturing Industry's Efficiency Based On Value-added Rate

With the rapid development of economy in our country,the manufacturing industry made great progress,and the products made in China are all over the world.When the total manufacturing get astonishing achievements,the development of the manufacturing industry in our country is faced with serious problems such as manufacturing big but not strong,lack of core technology,low competitiveness and so on.Value added rate is also known as value-added rate,which can reflect manufacturing value-added,profit level,the effect of input and output,It is the integrated embodiment of its manufacturing level of profitability and development,manufacturing value added rate directly decides the development level of an industry and benefit level.Through the comparative analysis of the value-added rate,we can find out the gap between our country manufacturing industry and the developed countries.In addition,the study of the influence factors of manufacturing value-added rate the can promote the increase of the added-value of China's manufacturing rate and lead to promote the adjustment of industrial structure and industry transformation upgrade.Firstly,this paper analyses the problems in the economy of our country,put forward the necessity of value-added rate to evaluate the economic growth.Secondly,according to the 1995-2011 world input-output database(WIOD)collection the data of Germany,the United States,Japan and China,describe the change rule of various countries' manufacturing value-added rate,comparative analysis the added-value of different technical level of manufacturing industry all over the world,clearly point out the gap between China manufacturing value-added rate and developed countries abroad.Then,according to the input-output table of our country in 2007 and 2007 analysis the main reason of our country's manufacturing value-added rate.The results show that the value-added rate caused by structure rate changes make our overall manufacturing value-added rate dropped by 0.2302%,accounting for 24%of the total of the variable.Manufacturing industry segment itself value-added rate's change makes the overall manufacturing value-added rate dropped by 0.9761%,accounting for 76%of the total the variable,which shows that the main cause of China's low manufacturing output rate is the cause of deterioration of the manufacturing structure is not set up.Finally according to the conclusion,build a panel data model,regression analysis the influence factors of affect manufacturing value-added rate,in this paper,the results show that r&d strength,comparative labor productivity,current asset turnover,output value proportion,the ratio of fixed assets and main business income and total assets utilization indexes can affect manufacturing value added rate.To eliminate the gap between the manufacturing industry segment,this article could be divided into high,high technology manufacturing and low,low technology manufacturing industry according to the technical manufacturing,respectively panel regression for manufacturing industry of different technology level,it is concluded that the same index of different technical level of manufacturing has different influence.In addition,this paper introduce new index for manufacturing value-added rate of return,which makes a more comprehensive analysis of the reason that manufacturing value-added rate changes.Through the analysising of data model,manufacturing value added rate is associated with R&D,the increase of R&D investment and investment efficiency can improve manufacturing value added rate,therefore this article then analyzes the R&D efficiency of manufacturing,thus clearly China manufacturing R&D efficiency,in order to more effectively improve the value-added rate.
