The Feasibility Study For Enterprise Participation In Project Of Space Development Over Elevated-road Based On Extension Theory

The construction of elevated roads in cities has solved traffic jam while it brought some environment problems, such as noise pollution, air pollution and ecological imbalance. With the improvement of living standards, people are increasingly seeking high quality life, such as comfortable resting environments, convenient shopping and traveling. To meet the shopping needs of residents establish a closed commercial corridor in the elevated road, we can call it The Elevated Road Space Development, not only to bring some opportunities for business and economic interests, but also to solve the problems of noise and air pollution. However, quasi-public good characteristics of such projects have a higher risk of business investment compared with the general competitive projects; and public welfare of such projects are not particularly clear, unable to draw attention to the government's public sector. Therefore, the ability to attract corporate investment in the kind of quasi-public projects is the key of the question. But the research on this issue is still relatively weak, little research in this area; especially research of such quasi-public enterprises to participate in the outcome of the feasibility of the project is no public reporting. So, this article drawing on research findings of project feasibility for such features of quasi-public projects ,based on extension theory and methods to study theFeasibility of the elevated road space development projects which have enterprises to participate in. The main contents are:(1) Designing analysis of extension evaluation based on extension theory as the quasi-public project feasibility characteristics of transformable and dynamic(2) Based on Services location theory, construction projects and methods of economic evaluation parameters and the results from the elevated road space enterprises to participate in development projects in features and characteristics of such projects, analysis the factors which work upon feasibility of quasi-public project and enterprises to participate in such projects, determine the extension evaluation parameters.(3) Invite experts and sector leaders form enterprises and government public sector to make scores for each index, and weight each index by the Fuzzy AHP Method. (4) On the basis of existing research results about evaluation parameters, determine classical domain and extension domain for each index by Expert Advice Method. Then, construct comprehensive evaluation system for feasibility study in perspective of project itself and business interests.(5) Select the eastern Xiasha space development projects around the city as an example, after field survey making the preliminary design of the project and got the actual characteristics of each index value. Then gain extensive evaluation results by adopting Evaluate App Software(6)After analysis the extensive evaluation results, give the suggestion for enterprises how to participate in such projects, and the government how to support enterprises to participate in.This paper has concluded that:(1) only with enterprises participate in space development elevated–road is infeasible, but with the support of the government, such as the government investment, cut down tax and fees, Enterprise participation will become feasible;(2) the Extension theory, Extension evaluation parameters, index weight, and the rang of indictors (classical domain and extension domain) are of reference.
