The Research Of Fuzzy Comprehensive Appraisal Of Green Technology Diffusional Environment

Scholars both here and abroad widely accept that diffusional environment is one of the most important factors to influence green-technology diffusion. To eliminate or conquer green technology diffusion obstacles so that to promote green-technology's rapid and broad diffusion, most researchers bring forward a series of suggestions of improve diffusional environment. But research results are not consistent and systemic, comprehensive and dynamic researches about diffusional environment are still not many, especially quantitative analysis about it.Sustainable, dynamic and economic features of green technology decide the features of environment factors that effect diffusional efficiency. Based on system theory, evolution economics and institutional economics, this paper clarifies environment factors' hierarchy and construction, and reveals many environment factors' effect mechanism on green-technology diffusion. After that, the paper puts forward that it is from diffusional environment searching, choosing, spreading and learning green-technology's function to quantificationally appraise environmental quality.According appraisal's goal, the paper sets up the evaluation indexes system of green-technology diffusional environment. Because evaluation indexes are complex, correlative and including qualitative indexes, the paper decides to use fuzzy comprehensive appraisal method. The paper discusses a detail fuzzy comprehensive appraisal model and many methods to determine index weights.At last, we use the established method to appraise current green technology diffusionl environment of china. The result is that compared with other countries Chinese green technology diffusional environment quality is moderate.
