Research Of Small And Medium-sized Enterprise Growth Based On Fuzzy Comprehensive Evaluation

With the reform and opening of china, the Chinese capital market has already formed its shape after decades of exploration and development. As the main body of the capital market, listed companies have grown both in number and scale, and become a major part of national economy gradually. Established and expands with great attention and expectation, however, the development of listed companies turns out to be pessimistic, as a matter of face, the growth of numbers of listed companies is to be worried about. On the one hand, with the bankruptcy of some listed companies, the growth of listed companies aroused the attention of the accounting theory and industry circle. One the other hand, as the standardization of capital market and the immatureness of investor's mind, researches on enterprise growth are badly needed. All of this made the research on enterprise growth more than an academic issue, it also matters the development of listed companies and capital market. Besides, the fuzzy extension of the enterprise growth concept makes fuzzy comprehensive evaluation the preferred method. Thus, the research of enterprise growth based on fuzzy comprehensive evaluation is theoretically and actually significant.On the basic of relative studies of the issue, the dissertation elementarily chooses some evaluation index with reference to the enterprise growth theory. Then we select those indexes by SPSS and finally found an evaluation index system of enterprise growth. Standardization is also conveniently made for measuring the evaluative index, that is, to count the average value of every index and plus/minus a standard deviation as the highest and lowest critical value. Meanwhile, to avoid the influence of the set of index weight on the validity and objectivity of fuzzy comprehensive evaluation model, we use Principal component analysis and rotation-combination to choose the index, and ensure the weight of every index according to their contribution. On this foundation, we combine fuzzy comprehensive evaluation, set of weight and matrix of fuzzy membership grade to build the growth model of listed company on the principal of the maximum membership grade. Finally, we also tested the model positively.
