The research on relationship between IT capabilities and firm performance is hot. However, we found that many studies regard the IT capability as a whole ignoring the types of IT capabilities. Meantime they do not take into account the industry environment conditions that influence the relationship. First, we propose IT capability can be divided into IT capability of base, IT capability of application...
Construction project has long been suspected to fail to provide information. Incomplete information provided by cost management system has the potential to misdirect decision making by construction project manager. Construction project need a cost management system that can provide effective information about their project, markets, customers, and counterpart. Through comparison of activity-based...
DEA method can be used to establish input-output model to evaluate the input-output of the construction of enterprise informatization. The index weight has an important effect on the results of the evaluation. By joining the weight limit into DEA input-output models, it can objectively reflect the extent that the decision makers pay attention to different indicators. By doing this we can make the...
To prevent cascading failure of complex networks more efficiently, the best preventive strategy for cascading failure model based on random-walk betweenness (RB) should be investigated. Limited resource cascading failure model based on RB is proposed, which can be used for comparison of different preventive strategies. By the invulnerability simulation in scale-free networks, the efficiency of 2 proposed...
Counter party credit risk of the financial derivatives transaction is the risk that one party has a default before the expiration of the contract. This research investigates the unilateral counter party credit risk of credit default swap (CDS). Under different assumptions, three different information models are built. They are, the basic model with no counter party credit risk, the model considering...

Spent Fuel Reprocessing is a part of nuclear fuel cycle and is the inevitably choice of nuclear power sustainable development. The reprocessing needs to face with radiological, criticality and chemical hazards. It is beneficial supplements that using the appraisal method of based on spent fuel reprocessing system security engineering capability maturity model. Experts should check and approve large...
Unlike former methods for competitor identification, this paper for the first time applies a two-dimensional index system (market commonality and resource similarity) as criteria. Based on the dynamic competitor analysis framework put forward by Professor Chen Mingzhe, the author employed quantitative statistics methods of cluster analysis and matching analysis to identify and classify the dynamic...
It has important theoretical and practical significance for urban agglomerationSs functional integration. Based on functional integration in the urban agglomeration and its effect with qualitative analysis¡Ataking Yunnan central urban agglomeration for example, this paper examins and measurements the development effects of functional integration, by building co-integration equation and spatial convergence...
Since 2010, the central government of China has introduced a series of tightened policy to limit too fast ascension in housing price. This paper proposes a method to estimate the effect of housing price fluctuations on the macro-economy. In the model, housing price fluctuations not only change housing market situations, but also the productivity of construction and real estate sectors. Stress testing...
This paper analyzes integrated innovation network co-operation between enterprises based on innovative knowledge sharing behavior with evolutionary game model. Through theoretical analysis, it is found that coordination coefficient, penalty coefficient, the cost of knowledge transfer, innovation gains and the shares in the innovation gains of members and so on will affect the success of cooperation...
Aiming at the independent distribution units of multi-access system, a remote door access management system is researched and designed based on Ethernet. The system uses MSP430F149, together with W5100, to be the control core of every access system unit, and to achieve real time data communication between the access controller and the upper monitor based on TCP/IP protocols. The communication mode...
