    The Dynamic Interacting Relationships Among the Operating, Investing and Financing Cash Flows
    HAN Li-yan, LOU Jing
    2010, 18 (2):  1-7. 
    Abstract ( 2611 )   PDF (987KB) ( 1915 )   Save
    This paper investigates the dynamic interacting relationships between the operating,investing and financing cash flows with a Panel Vector Autoregression (PVAR) model,which treats the above three variables as a system,mitigates the problem of endogeneity in the estimation,and displays the responses of one variable to the shocks from the others in the cash flow system. With the sample of the listed firms of China's manufacturing industry,the results of the sensitivity analysis of the coefficients and variance decomposition show that,the level of the investing cash flow is more sensitive to the operating cash flow, while the volatility of the investing cash flow derives more from the financing cash flow. Furthermore,the orthogonalized impulse-response functions manifest that,the operating cash flow is insensitive to the shocks from the investing and financing cash flows;the investing cash flow exhibits lasting and significant responses to the shocks from the operating and financing cash flows;and,the financing and operating cash flows evidence short-term substitution effect to some extent. In an overall view,the above findings demonstrate the evidence of the financial constraints of the listed firms of China's manufacturing industry observed from cash flows'sensitivity and volatility aspects.

    Abstract ( 2543 )   PDF (1769KB) ( 1157 )   Save
    Investmentinstitution can take some asset allocation strategy to change the risk of paying return guarantees.Therefore,the risk of return guarantees should be associated with asset allocation strategy.This paper proposes a new approach combined with asset allocation strategy,through which we respectively obtain analytical solution of risk under constant-mix(CM)and constant proportion portfolio insurance(CPPI)strategies.Then,we prove the feasibility and rationality of the new approach through empirical studies. According to the new approach, the risk calculated can change with asset allocation strategy or strategy parameters,which will help investmentinstit ution and regulatory agency to guard against financial risk better and improve the efficiency of risk management.

    Abstract ( 2593 )   PDF (525KB) ( 1602 )   Save
    In capitial asset pricing theory,it is a fundamental assumption that the extra returns of securities have constant variance. However,this assumption is not always realistic,thus it is necessary to check of this assumption. Under the Bayesian framework,the paper is devoted to constructing Bayesian test for the autoregression conditional heteroscadasicity (ARCH) of the CAPM with structural change. In the end,the effectiveness of the developed approach is illustrated with a real example.

    Abstract ( 2715 )   PDF (714KB) ( 2461 )   Save
    LGD(Loss Given Default) is one of the main element in credit risk management. Under the framework of the structure credit risk model,we develop a LGD analytic expression,in which the corporate value drift rate is replaced by risk free rate. The distribution,the association with PD(Probability of Default) and the factors which influence LGD are investigated,including term of loan,corporate asset-liability ratio,risk free rate,and loan size. With Sichuan large size non-perform loans data,the results are empirically tested on aggregate level.

    New ANP Metasynthesis Approach with Respect to BOCR Merits Based on Data Envelopment Analysis
    LI Chun-hao, SUN Yong-he, DUAN Wan-chun
    2010, 18 (2):  55-61. 
    Abstract ( 2537 )   PDF (968KB) ( 2021 )   Save
    The analytic network process (ANP) is an efficient multiple criteria decision method to deal with complex decisions. However,the existing ANP with consideration of BOCR merit factors does not always yield correct ordering of alternatives and indication of profitability,due to the fact that different hierarchies or networks produce weights on different derived ratio scales which are usually not commensurate. To overcome the above drawbacks,this paper proposes a new ANP meatsynthesis method with respect to BOCR merits,based on data envelopment analysis. When estimating each weight for four BOCR factors, we adopt the means of swing weighting to reflect the inaccuracy and fuzziness of a decision-making. Applied to a specific example,the suggested approach is validated to be suitable to real world ranking problems for complex systems.

    Abstract ( 2581 )   PDF (1237KB) ( 1876 )   Save
    A major inducement of food safety accidents is the unbalanced supply-demand relation in food logistics. Based on logistics balance,this paper builds a food risk propagation model which simulates a complete supplier-to-consumer chain,and then analyzes how different supply-demand relations effect the food safety and the decision-making of individual actors,by using computational experiment. The research resups explain the inevitability of some current food safety accidents from logistics balance dimension,and reveal that different supply-demand relations lead to different level of food safety. Specifically speaking, the higher tension there are,the higher risk there will be. In the case of an extreme unbalance supply-demand relation,government regulation can,only control malignant spread of hazardous substance in a limited extent rather than guarantee it fundamentally. Comparing and contrasting with static supervision,the flexible and dynamic regulation is more efficient in food safety control. In addition,logistics relation and regulatory strategy effect the upstream of food supply chain deeper than it that on downstream.

    Irresponsible corporate behaviors are constrained by both government regulation and product competition. This article builds a three-stage game model,analyzes the impact of government preference and execution on government regulation of irresponsible corporate behaviors,and reveals the paradox of government preference. Research shows that the key for a government to constrain irresponsible corporate behaviors effectively,is to make corporate losses from irresponsible behaviors exceed gains from those;no matter how the government prefers social interests,there exists a possibility that the government deregulates irresponsible corporate behaviors;the more the government prefers the social interests,the less a possibility of eliminating an irresponsible corporation from the market is;and,the paradox of government preference results from the duality of irresponsible corporate behaviors.

    Western-China cities are on the period of fast and stable growth. To measure Western cities'e-conomic development level and growth trend,per capita budgetary income,per capita GDP and correspondent annual growth index are applied.Per capita budgetary income and per capita GDP are used as the two indicative parameters of economic development level. Per capita budgetary income is the ranking criterion of cities,since it has more strict restriction in public economy. Based on the data of population,local budgetary income,and local GDP in the period of 1998-2007,48 cities are divided into three groups as the objects of panel data measurement. The contribution rate of per capita GDP to per capita budgetary income,the annual growth rate of per capita budgetary income,and the annual rate of per capita GDP are measured The results indicate that,the annual growth of per capita budgetary income,the contribution rate of per capita GDP to per capita budgetary income are positive benign indicator of urban economic development. Yet the positiveness of annual growth rate of per capita GDP needs careful analysis based on particular situations. Research indicates that,the scale economy in western-China cities has two forms: super large cities exploited the advantages of the scale economy of the scale of public services,while the medium-sized cities would exploit the scale economy of dominant dominant industries. There are great differences on economic development level among western-China cities. Cities with comparatively lower development level should a山ust the growth strategy,and need corresponding public policy support.

    The emphasis of research on team learning has been shifted from basic problems (e. g. definition and typology) to the exploration of its inner mechanisms (e. g. the causal relationships).Yet,there are still not a significant numbers of studies on the relationship between team diversity and team learning. We define the concepts of team goal preference diversity and knowledge and experience diversity,and then discuss in detail how the two types of diversity affect team learning capability. Our result shows:Teams with higher goal preference diversity tend to have lower learning capability;The higher team knowledge and experience diversity will lead to higher team learning capability;The interactions of the two orientations are important moderating variables between the two types of diversity and team learn capability,that is,when the two types of interactions are frequent,the negative effect of team goal preference diversity on team learning capability are weakened,and the positive effect of knowledge and experience diversity on team learning capability are strengthened;The effect of knowledge and experience diversity and team performance are mediated by team learning capability.
