A Quantitative Method of Assessment on Development Level of Regional Economic Based on D-S Theory

D-S theory is a popular assessment method on physical science. For this method, first, the scope of research regions should be determined, then some samples selected randomly from the sample space which is set up, so the samples quality can be assessed based on fuzzy theory. And then, the results of these assessments should be put as a “different sources, used to assess sample” multi-channel information, and the information be integrated in order to get the assessment results of the entire sample space based on D-S theory. At last, the assessment results can be explained as confidence interval is [0, 1].This text takes a province as an example, the economic development level of the province is 0.65286 based on this method.
