This paper studies the strategy of service positioning of a potential entrant of the market within the Hotelling spatial competition model. It is shown that the entrant's service position in a two-stage game can be achieved from minimum differentiation and maximum differentiation, depending on the strength of the cooperation and competition. The effect of the cost differentiation on the entrant's...
The objective of this paper is to address a typical eco-efficiency analysis problem, in which undesirable outputs and categorical variables should be considered simultaneously. By analyzing the impacts of categorical variables on decision making units' (DMU) desirable and undesirable outputs, a modified DEA (Data Envelopment Analysis) model is proposed. In the proposed model, a new approach of defining...
As the mobile agent technology begins to emerge as a viable solution for intelligent e-commerce applications, there is an increasing attempt to ensure that the systems being developed are robust, reliable and manageable. While the mobile-agent-based e-commerce systems are designed and implemented, their functional correctness and completeness must be formally verified. For this purpose, this paper...
Model of integrated assessment of e-government Website is the one of the key problems to promote the construction and development of the e-government. We first establish the index system of assessing e-government Website, this is the index system of hierarchical structure and these indexes are divided three layers; then, based on the basic principle of the Analytic Hierarchy Process(AHP), we can get...
There are two aspects in the growing demand of the converged-innovative products. The first is that the converged products substitute the original market demanding, and the second is of creating the new market demanding. Thus, based on redefining the concept of technological convergence, we analyze market demand of convergent products according to the characteristics of technological convergence in...
Methods for enterprise architecture, such as TOGAF, acknowledge the importance of requirements engineering in the development of enterprise architectures. Modelling support is needed to specify, document, communicate and reason about goals and requirements. Current modelling techniques for enterprise architecture focus on the products, services, processes and applications of an enterprise. In addition,...
In the accessory inventory system of manufacturing enterprise, n accessory providers and one manufacturer are selected to research on. Basing on the operating status of the system and using the inventory control theory of operational research, economic effect models of every participate enterprise are set up. The paper also analyzes and discusses the models, and the important significance of the models...
Cash flow is the basis of value evaluations of listed companies. Based on the complete sample data from the Shanghai and Shenzhen Stock Markets during the year 1998-2005, we compared the value correlations among CFO, FCF and TCF using pricing model and benefit model, and found the value correlation of CFO, and then analyzed the differences of the value correlation of cash flows in different years.
Competition game and interconnection sequential equilibrium between two IBPs (IBPs: backbone providers) are studied to promote development and make out reasonable interconnection policy. For the former, the paper emphasizes the relationships between corporation profits, social welfare and interconnection quality. It concludes that interconnection between IBPs should be hierarchical and differential,...
A multi-stage cooperation and competition model based on flexibility in port service supply chain consisting of a port enterprise and two service providers (SP) is built, using Stackelberg model and Cournot model. Flexibility in port service supply chain is studied. The influence factors of port enterprise's flexibility strategy and SP's flexibility strategy, relationship of port enterprise's flexibility...
The disparities among our country mortality rates per million tons in coal mine and other main mining countries is great, so the coal mine safe production becomes the noticeable questions, which keeped an eye on by the community more and more. Same as other industry profession safety, the coal mine safety has close contact with national economic development in addition to the safety engineering technology...
On Dec 8th, 2003, the top price levels showed in the limit order book were enlarged from three to live in Chinese stock market, and the transparency was largely increased. The paper studies on the contribution of every quote price to price discovery, and compares with contribution of before and after transparency was increased.

Changes in market interest rates led to the changes of bank's assets and liabilities values, which led to the change of the owner's equity of the bank and bring in risk to the bank owners. As a result, interest rate risk management of commercial banks is extremely important. We built a portfolio optimal model for bank assets and liabilities management by controlling the interest risk, which controls...
Based on the characteristics of IT firm, the principal-agent model between the owner and manager of IT firm is established by use of information economics theory, the gross benefit of the owner or manager is compared in two situations of symmetric information and asymmetric information, and the relations are studied among risk aversion, stock incentive, effort level of the manager, contract time and...
This paper has two goals. First, it aims at introducing the basic notions of Monte Carlo simulation techniques, when those methods become relevant and how they can be applied efficiently. Simulation is indeed often the most performant model evaluation tool, and can even be the only solution technique to analyse complex models. Output analysis, through a properly designed confidence interval, and variance...
With aggravating of market competition, the operation of supply chain coordination becomes more and more important. Therefore this paper firstly describes the capability and profit of supply chain members and the operation of supply chain coordination using multiple-objective programming and proposes a multi-product, multi-stage supply chain coordination model based on VMI ,which comprises one manufacturer...
The fictitious economy and real economy constitute a new pattern of economic system in the modern society.
