Abstract:The paper is an effort to establish some hypotheses on the causes of the price-falling in recent years in Chinese economy. Based on theoretical analyses and preliminary statistical support, the paper points out that , the price-falling accompanied with the lower growth of investment GDP during 1997—1999 was mainly caused by the credit-crunch and was a kind of typical deflation; but the price-falling accompanied with the increasing investment and high growth of GDP during 2000—2002 should be explained by the efficiency improvement and decreasing costs of production and should be termed as “efficiency price-falling", which shared some similarities with the price movements in early stage of Industry Revolution and capitalism in 19th centurys Europe.

Abstract:At present,Chinese economic growth is just moving on the overspreading stage of its business circle.The fix assets investment growth is just on the overspraeding stages of its short-term circle and medium-term circle.And the industry structure upgrade is on the recession stage of its medium term circle and the recovering stage of its long medium term circle.Adapting to all these periodic waving features of different economic activities,Chinese GDP growth is just on the overspreading stage of its short-term circle,the recovering stage of its medium term circle and the bottom of its long medium term circle.Chinese economy has already got into a rapid growth period,but the economic growth speed will not wave intensely in short term.The government should still adopt neutral macro\|economic policies at present.

Abstract:The thesis discusses the optimum consumption and the decision mechanism of saving with reference to Solows economic growth model and Ramsey-Cass-Koopmans model, deriving the golden rule of judging the dynamic efficiency of macro-economic operation and modifying the standards of golden rule. The possibility of dynamic inefficiency in a free competitive economy is also explored according to the overlapping generations model. On the basis, we have investigated the dynamic efficiency of Chinese economy with the golden rule, drawing the conclusion that the economic operation in China since 1990s has been in a state of dynamic inefficiency. Afterwards, we have analyzed the causes of dynamic inefficiency in Chinese economy. In the end, we have put forward some policy suggestions on escaping from the dilemma of dynamic inefficiency based on the facts and reasons of dynamic inefficiency.

Abstract:This paper develops an endogenous economic dynamic model without equilibrium based on the real world. In this model, dynamic paths of market prices, cycles of consumer goods and capital goods are driven by endogenous variables through intra-sector and inter-sector relationships. Market disequilibrium processes, inventory adjustment mechanisms, as well as optimal and adaptive behaviors of economic agents are modeled based on real-world observations. Stationary and stability properties are discussed as special cases of general market tatonnement dynamics.

Abstract:Many researches are related to the data of capital,but the data used in the passed research are greatly differentiated,and thus influences the accuracy of related research works,so its necessary to recalculate the capital of China.This paper have discussed five aspects about the method of calculating capital in detail and worked out the data of capital of China by using of our own methods.

Abstract:This paper develops a comprehensive framework to analyze the relationship of monetary policy and stock market.We focus on the necessity and efficiency of central bank intervention in the stock market in China.We applied rolling VAR estimation and augmented VAR Granger causality testing technique to capture the frequent structural changes in China due to her gradual economic and financial reforms.It provides a new analytical framework for the central banks monetary policy design and its forecasting practice.

Abstract:The present article brings forward a theory that explains the energy of finance release in an economic entity.The article explains that energy of finance is determined by the scale of financial resources and the unit output capability of the financial resources processed by the economic entity.The level of the energy of finance release is one of the main factors that influence the level of the GDP.The article also formulates a theoretical model to analyze the energy of finance release.On this basis,the author does a further exploration on the restrain of Chinas energy of finance.The article comes to a conclusion that the key to a energy of finance release is to realize a competitive distribution of financial resources in the economic entity.

Abstract:In the past years, the relation between capital structure and competition among firms in product markets relates to two different science fields, that is of Corporate Finance and Industrial Organization. The paper puts forward a theoretical hypothesis, and develops a model related to test this relation. Our theoretical analysis shows that the decision of capital structure, being a firms promise to market, indicate to other firms that its competitive action will be even tough or soft, that it performs an important function to send signals to outside, meanwhile, it could produce strategic effects. Firms capital structure is significantly and positively related to the competitive degree of the firms in output market, and the empirical tests, using the data of listed firms in Shanghai and Shenzhen capital markets, support our theoretical analysis predications, which has great enlightenment to firms in their decision making.

Abstract:This paper, based on some reasonable points of other literatures, discusses the relationship of asset size, risk type and value of collateral in term of signal screening and costly monitoring, which are integrated in a model of credit rationing with endogenous collateral and firm asset size. According to this model, we try to find the reason why SMEs and some high-risk enterprises are wept out from credit market. The theoretical model could be useful of understanding the problems of SMEs on credit market in market economy and transitional economy.

Abstract:The paper is based on the academic paradigm “technological capabilities of enterprises”, and employs the model of strategic choosing of technological learning. From the theoretical aspect, the paper analyses the practical dynamic causes for the enterprises to choose the technological learning strategy. With the exemplification of cases, the paper researches into the Chinese enterprises behavior mechanism of technology choice, and then gives concerned advices.
