A Study On Theory And System Framework Of Construction E-Business

Accompanied by the ages of information and internet, e-Business integrates the all including individuals, enterprises, organizations and governments. The construction industry is a supporting industry for national economy, accommodating large employment and related with the other industries obviously. So, it has meaning to study the e-Business in construction industry. The theory and system framework of CEB (Construction e-Business) is studied in this paper, using the methods of web search, literature research, data analysis, analogism, conceptual model and mathematic model. First, through data analysis, the straight line development trend of China internet is discovered. Compare the construction industry with the manufacturing industry, it is showed that after year 2002 the informatization popularization rate of the construction is straightly lower than the manufacturing industry, and is below the national average level. Elicited by the IT productivity paradox, it is considered that IT is a necessity of construction enterprise, but the competitive advantage of construction industry can't be gained through IT only.And then, the competitive advantage theory, as a basic enterprise theory, is reviewed. Then, through deep e-Business analysis, the value of e-Business contributes to construction enterprise is set forth. Based on the theory of competitive advantage, the challenge of construction industry in business strategy and informatization is expounded. Thereout, the CEB theory is raised and the competitive advantage of CEB strategy is analyzed by the Five Forces model. Through taking apart general enterprise to three main factors and set forth the basic hiberarchy structure, based on system theory the general system framework model of CEBS and NIC (network integrated construction) platform model are designed. Consequently, the object of enterprise-project integration and business-IT integration comes true.The 3D compositive evaluating model for CEBS is designed, which guarantees the inside and outside, historic and iterative knowledge accumulation, and the whole process control. Finally, the main conclusions and creation are sum up, the shortages are pointed out, and stress and orientation of the future research is prospected.
