Research On Evaluation Index And Method Of The Competitive Ability Of The Construction Enterprises

China's construction market develops rapidly, but there are some problems in the process of development, such as imbalance between supply and demand, excessive competition and unperfcet competition mechanism etc. The existence of these problems seriously restrict the further development of the construction market. Managers need to pay attention to and think about the question of how to analyze construction market competition factors and evaluate reasonably the competition ability of the construction enterprise in the industry from the perspective of the principle of market competition. Many study methods will be used including literature reading,theory anlaysis, combining normative research and empricical research, combining qualitative and quantitative methods to support the study on the mechanism of competition of construction market in China which from the following serveral parts:First of all, it will have certain knowledge and understanding of the competition situation of construction market in our country by the use of literature research, and to analyze China's construction market competition mechanism including the construction market from invisible to visible change, "two mechanisms", the development of the bidding mechanism, bill of quan tities and the market main body responsibility system. Based on the theory of industrial organization, it analyzes the problems in Chinese construction market and the construction market competition requirements from the market structure and market behavi or two aspects by using the method of combining statistical analysis and literature reading, and analyzes the development of the relationship between the government and the market furtherly, which put forward the basic requirements of decentralization and increasing the market effect from the angle of deepening the reform.Secondly, it gradually discusses the competitive factors in the construction market from the market economy principle based on the requirements of the construction market competition,and analyzes the principles of futures theory, resource allocation principles, supply chain, the value chain, then puts forward comprehensive competitive factors cientifically and comprehensively based on the system engineering,and constructs the construction market competition evaluation framework.It constructs the construction market competitive factor model in China by analyzing the relation between factors.And it puts forward the evaluation of competition ability of construction enterprises from the element s of the principle of market economy through the discussion of the relation between market and enterpriseAgain, Under the background of the management system which proprietor commission the construction supervising units to implement the construction of project, the quantitative evaluation index system of the project management strength of the bidding enterprises is built which is more objective to record the project management capabilities and is counted by the third party relying on the Internet era of big data project management coordination platform. Weight determination of indexes uses Fuzzy. the system of index is divided into annual indexes with small fluctuation and quarter indexes with big fluctuation, and then it studies the evalution method of the project management strength of the bidding enterprises.It uses a linear fitting interpolation and the average method to evaluate those annual indexes which depends on whether show an increasing or decreasing trend and Markov Forcasting method to evaluate those quarter indexes in order to reflect the trend evaluation of the project management strength of the bidding enterprises. Analytic Hierarchy Process to avoid consistency index weights repeatedlly tested, and finally it verifies the feasibility of the model with an example.Finally,according to the evaluation index system of competition ability of construction enterprises and combining with the analysis on the exsiting problems in the construction market,the suggestions of the competition ability of co nstruction enterprises is put forward.
