内容提要: 本文针对近年来我国房地产市场价格持续攀升但市场需求不降反升、银行信贷资金迅速向房地产业集中以及房地产市场发展与经济增长的作用等问题，以全国和各省、市、自治区的面板数据，进行了实证分析。分析结果显示，我国房地产市场供给约束问题非常严重，尤其是考虑到居民收入增长因素后，房地产市场的供求矛盾十分突出；银行房地产开发贷款和个人住房贷款强有力地支撑了房地产市场的供求；房地产市场的发展也拉动了经济的增长，但这一作用没有我们想象的大。因此，目前我国针对房地产市场的宏观调控和各项监管措施，都应该从供求两方面出发，在金融等政策上要保持连续性，并加强制度建设，更好地发挥市场机制的作用。 Abstract: Recent years, with the rising price, the housing demands also rise quickly, which is strange to the common sense of economics. In addition, the relationship between banking sector and housing industry has become more and close, and the growth of housing industry pull the economic growth dramatically. Based on the panel data of the nation and provinces, we try an empirical study on the topics above. The empirical results show that at least in the nowadays China’s market, one of the most sever problem in the real estate market is the constraints of the housing supply compared to the demand if we consider the effects of the resid ents’income growth. Bank loans are maybe the most effective factor pulling the housing industry growth, both on the supply side and the demand. To our surprise, the effect of housing consumption on the economic growth is less than we have assumed, considering the cyclical changes of the economy. . So we draw the followed policy implications in the further macroeconomic managements: we must take the measures directly to both the supply and the demand sides, keep the policies’ continuity, strengthen the institutional progress and make the market mechanism more effective.

College Students’ credit in loan has become the focus of the authority of universities and commercial banks. It is therefore very imperative to establish the appraisal system on the credit of college students and it is pretty important and urgent for the business growth, decrease of risks. In the light of experience of developed countries in college students’ loan and personal consumption loan, the paper aims to design an appraisal system that fits China’s situation well

摘要：作者对实际使用的对冲模型提出研究，在本文中建立了一个在指数.指数期货.指数期权上的进行无套利对冲的前沿模型，揭开了对冲基金使用数量模型神秘的面纱。通过比较从市场指数和指数期货中估计得出的风险中性密度函数与从隐含在指数期权市场的风险中性密度函数，发现对冲机会，设计对冲交易策略。我们这里采用的估计方法为非参数方法,是对BS模型的拓展。 Abstract: In this paper, the authors make a research on the field of hedge model, after the investigation of some hedge funds in U.S. ,we establish a frontier no-arbitrage hedge model for index.index futures and index options. We compare the risk neutral density estimated from cross section of index market to the risk neutral density inferred from the time series of index and index future markets. The methods we used are nonparametric method and hypothesis test. We can find the arbitrage opportunity and design the hedge trading strategy.

It is a striking economic phenomenon that China’s foreign exchange reserves reached $US 606.9 billion. This paper pursues to explore the underlying motivations and implications by not only analyzing the complicated relationships between the Chinese economy and foreign exchange reserves but also establishing a tentative model to evaluate the adequacy of foreign exchange reserve holdings. The model has successfully confirmed that China’s recent holdings of foreign exchange reserve, in particular in 2004, appeared to exceed the adequate level largely due to speculative hot money inflows when the Chinese currency Renminbi had been expected to appreciate.

Financial market is a typical complex system because it is an open trading system and behaved by a variety of interacting agents. The consequence of the interaction appears quite complex and nonlinear. Therefore, how to observe this system and find a simplified methodology to describe it is, probably, a key to understand and solve the problem. In this paper, the author observes a stationary transaction volume distribution over a trading price range, studied the relationship between the volume and price of transaction through the amount of it in stock market. The probability of accumulated trading volume (i.e. actual supply/demand quantity or transaction volume) that distributes over a trading price range gradually emerges kurtosis near a transaction price mean value in a transaction body system when it takes a longer trading time, regardless of actual trading price fluctuation path, time series, or total transaction volume in the time interval. The volume and price behaves a probability wave toward an equilibrium price, driven by an actual supply/demand quantity restoring or regressive force that can be represented by a linear potential (an autoregressive item in mathematics). In terms of physics, the author derives a time-independent security transaction probability wave differential equation and obtains an explicit transaction volume distribution function over the price, the distribution of absolute zero-order Bessel eigenfunctions, in a stable transaction body system when its supply and demand quantity is dynamic. By fitting and testing the function with intraday real transaction volume distributions over the price on a considerable number of individual stocks in Shanghai 180 Index, the author demonstrates its validation at this early stage, and attempts to offer a micro and dynamic transaction volume/price (actual supply/demand quantity and price) probability wave theory.

内容摘要：中国经济发展的重要目标之一就是保持国民经济快速平稳增长，实现这一目标必然要求从战略高度审视经济波动问题，把提高经济增长质量作为经济社会发展的基本优先目标。本文通过构建基于要素投入、货币供应与中国经济波动的AKM模型，采用1953-2004年样本序列数据，运用向量自回归模型（VAR）、脉冲响应函数（IRF）以及Granger Causality Test，实证检验了资本投入、技术进步、货币供应波动与经济波动之间的相互关系。实证结果表明：资本投入波动是经济增长波动的主因，货币供应量波动次之，技术进步引致的经济波动则更为平缓和持久。在较短的时期内，资本存量和货币供应波动更容易引致宏观经济波动，且波幅较大，而技术冲击则从更长的时期内对宏观经济波动产生影响。此外，我国技术进步并不内生于经济增长以及货币供应非中性的推论也值得重视。最后，文章就如何实现我国经济平稳增长提出了简要的政策建议。 Abstract: One of the most important objectives of Chinese economic develoment is to keep GDP growing fastly and stably. Realizing this objective, We must survey the problem of economic fluctuation from a strategic view and treat it as the basic and prior goal of economic and social development. Through formating AKM model and appling VAR IRF and Granger Causality Test with 1953-2004 data, this paper finds:the main reason of economic fuctuation is capital input and money supply follows. In a short term, the fluctuation caused by capital input and money supply is more easier and stronger, while technology impulse always causes macroeconomic fluctuation softly and durable in a long term. Otherwise we should also pay attention to the non-neutrality character of money supply and the non-endogenesis of technology progress . Finally this paper raises some brief countermesures.

In this paper we present a critical viewpoint on interpretation of one of the most important innovation in the recent world economy. This is erivatives’ market, the options segment in particular. The standard options such as plain vanilla, nonstandard exotics or hybrid options and more recent specification called credit derivatives are actively traded around the world absorbing a significant volume of cash flows. The goal of the paper is to present the misunderstanding of the core problems in this field. This is an option price discovery. The modern probability and statistics theories are applied to provide investors and institutions information regarding the cost of the investment risk and on the other hand develop a better proximity between given historical data and analytical theory. We will show bellow that critical arguments are related to the basic fundamentals of the investment sciences that unfortunately are still difficult to comprehend by theoretical researchers, supervisory organizations, and investors.

Abstract Universal corporate banks are defined as financial institutions that may offer the entire range of financial services, and own equity in financial and non-financial firms. The emergence of universal corporate banks is one of the responses of banks to the environmental changes in global financial markets. An idealized model of corporate bank is developed to describe the nature of corporate bank. The corporate banking policies include internationalization of financial services and information net-work, expansion and integration of corporate banking functions, creating close corporate clients relationship, acquiring knowledge and information advantage in corporate and financial markets, performance of corporate control and corporate governance to influence corporate management. Transaction cost and other theories are used to explain the universal corporate bank, especially the rationale for expansion and r-organization, for developing close corporate relationship, for acquiring information and knowledge of corporate clients, and the influence concerning corporate governance. In this study, the evolution of regulation, present situation of banking system, future development of corporate banking in some countries are investigated. It is found that free selection of organizational structure and financial activities of financial institutions is a general tendency in these countries. The problems such as conflicts of interest, culture conflict encountered when implementing corporate banking policies are discussed in this study. Different organization designs, management models, external regulations, and corporate culture are introduced as solutions. The development of corporate bank has great implications for financial reform in China. The pre-requisitions and barriers of developing universal corporate in China are discussed. A case study of China Construction Bank is utilized to illustrate the current situation and further development of banks in China. It is argued that a gradually financial liberalization with correct order should be accomplished. Some recommendations are produced for further reform of financial market in China including diversification of bank’s ownership, permission of foreign banks enter Chinese financial market, liberalizing interest rate, and establishing a fully floated foreign exchange market.

The integration of two vertically linked business units allows the single owner to choose the compensation contracts of the managers of the two units coordinatively and thus internalizes a production externality when there is technological synergy or complementarity. On the other hand, vertical integration changes the way in which a disagreement is handled when the two managers cannot agree on a transfer price for the intermediate product. Specifically, integration gives the single owner an extra option: transfer the product without establishing a price. Knowing that the owner cannot commit to costly outside trade, the managers have stronger incentives to disagree on the transfer price and hence the information that would be conveyed by the market prices is lost. Consistent with the conventional wisdom, two key determinants of vertical integration in our model are intermediate-product-market uncertainty and production synergy between the two units. The model yields new predictions linking both the integration decision and contract choices to several variables commonly thought to be important for vertical integration.
