| According to the theory of the growth of economic in economics, the growth of economic in a country is to depend on the investment of agent of production. But the sustained growth of economic which only depend on the means of production open to doubt in the region of economics facing the phenomenon that the differences about the growth of economic between different countries in the world. The high growth rate of economic in developed countries which depend on the low investment of agent of production impelled the study about the intangible capital that can explain the growth of economic which the putting in of means of production can't explained. The new theory of the growth of economic originated by S pointed that long-term development of economic depend on technical progress.So, intangible capital which on the base of technical progress become an object of study in the region of economic.According to new theory of the growth of economic, the increase of economic which can't explained by the investment of agent of production is called TFP which depend on technical progress. According to the fact: the more developed the economic is in a country, the high degree of TFP's contribution to the growth of economic. So TFP can bring the sustained growth of economic. According to many study, TFP is influenced by intangible capital and human resources. The analysis of Correlations between TFP and the investment of intangible and human resources during 1978 to 2007 obtain the conclusion that the relationship between TFP and the invest of intangible and human resources is a positive correlation, but the influence of intangible capital to the growth of economic is not obvious. At the same time , The analysis of Correlations between the efficiency and the investment of intangible and human resources during 1978 to 2007 obtain the same conclusion.The enterprise is one important resource which is used to product goods in favor of increasing the value of macroscopical economic. The analysis of Correlations between EVA of listed companies in China during 2005 to 2007 and intangible assets shows that the listed companies in our country need to increase the investment of intangible assets to strengthen the competition of company and to bring a positive effect to the growth of economic in our country. The relationship between EVA of companies and intangible assets of listed companies in Tianjin is analized at last based on the frontal study. |
