    On the Critical Growth Model of National Bonds Scale after the Bonds Internationalization
    SUN Wei, ZHANG Wei-peng
    2003, (2):  1-6. 
    Abstract ( 1914 )   PDF (2252KB) ( 1384 )   Save
    The paper suggested the stabilized burden rate condition to assure the reasonable growth of nation bonds scale,and established the critical growth model of national bonds scale after the debts internationalization.It showed that the critical growth rate of national bonds scale depended on the interaction of key variables of the economic environment.Also,it made a simulated calculation of the critical growth rate of national bonds scale in the different economic environment.The model will be helpful for management and alarms of national bonds scale after the debts internationalization in China.

    ZHUANG Xin-tian, HUANG Xiao-yuan, NIE Hong-mei
    2003, (2):  7-10. 
    Abstract ( 2159 )   PDF (1355KB) ( 1790 )   Save
    Financial networks is the circular flow of funds in an economy. In References[1-8] the model of financial networks have been researched.In this paper,we propose an improved model about assets,liabilities,appropriate sizes and prices,based on the financial networks models in references[1-8].This new model considers for all sectors the risks of financial instruments,the constraints for economic resource in financial networks,the constraints for the accountings of assets and liabilities. The improved model is more appropriate for application.We use the evolution programming algorithm to make simulations.

    Choice of China’s Foreign Direct Inverstment Pattern
    YAO Ling-zhen, YANG Da-kai
    2003, (2):  11-15. 
    Abstract ( 1904 )   PDF (678KB) ( 2122 )   Save
    China has been entered World Trade Organization,and will be held to the whole international market step by step.At the time of choosing the way of direct investment,more and more enterprises show very great interests in solely foreign funded business.The article analyzes the cost of losing efficiency in joint venture,and then finds joint venture is not always fit for international market,and sometimes unsteady.So joint venture must be transformed into single proprietorship. Along with the conditions maturing,solely foreign funded business will play the main role in the international market.

    2003, (2):  34-39. 
    Abstract ( 2041 )   PDF (1170KB) ( 2442 )   Save
    Based on a simplified rational investment model of financial distress firm,the paper analyses the characteristics of firm that fall into financial distress in investment decision.It will deviate from the reasonable investing behavior during the process of between the option gamble of creditor and the debtor.On the basis of the analysis,the author emphasizes the excessive investment of financial distressed firms during the transformation of economy pattern in our country and blindness,shourt term,and utilitarian in the debt reorganization.The excessive investment is the embodiment of insider control and the weakness of creditor’s right of bank.And the false debt reorganization is the real driver,which transfers the crisis to the business creditors.

    YE A-zhong
    2003, (2):  40-44. 
    Abstract ( 2202 )   PDF (934KB) ( 2332 )   Save
    Simultaneous equation models play an important role in making economic policies,analyzing economic structure and economic forecasting.This paper presents local linear estimators by GMM for every structural equation in nonparametric simultaneous equation models in the random design case that all variables in model are stochastic.We prove its consistency and asymptotic normality in interior by using laws of large numbers and central limit theorems in probability.Its rates of convergence in interior points equal the optimal rate of convergence for estimating nonparametric function.

    Risk Investment Policies for a Firm with Exponent Utility
    LIU Xia-qing, LI Lin, YANG Zhao-jun
    2003, (2):  66-69. 
    Abstract ( 2133 )   PDF (1229KB) ( 1539 )   Save
    Under the assumption of exponent utility, this paper treats optimal investment policies of a firm with a random risk process. The firm’s choice on investment can be savings, loan and trading of risky asset. The principal achievements are as follows: According to the fact that the interest rate on loan is higher than the one on savings, we acquire the optimal policies that maximize the expectation of terminal utility. Furthermore, we present an example of application in the end.

    2003, (2):  76-80. 
    Abstract ( 2077 )   PDF (679KB) ( 1949 )   Save
    This paper concerns the issues of technology selection among different stages of a product’s life cycle,in an environment characterized by multiple products,multiple periods and random demand.Partial flexible technology,defined as the ability to produce a subset of a product family,its investment and operational cost are highly related to its flexibility.Based on demand scenarios,a mathematical programming model for determining technology selection and capacity planning is developed to minimize the expected total costs;the described model is then applied to analyze the technology selection difference between a product’s introduction stage and mature stage.

    Abstract ( 2069 )   PDF (780KB) ( 2575 )   Save
    The external view of sustained competitive advantage is based on the assumption of homogeneity of firm,that is to say the firm is looked as a black box.Resource based view hold a assumption of heterogeneity.Because of the misleading of some essential concept such as the resource and focusing on the conditionals of SCA,the theory made a weakness is called black box on process that affect the theory’s development and application at management.This paper will divide competence from the resource,gives a new viewpoint about strategy based on the competence theory,embodies the framework of resource strategy performance,and finally develops a process orientation model about the causal chain of sustained competitive advantage.
