Abstract: In order to evaluate multiple systems at different times, this paper proposes a new dynamic evaluation method. Firstly, on the basis of the traditional ideal solution, a Vertical Projection Method is proposed to measure the degree of closeness to the ideal solution by using "Vertical Distance" instead of "Euclid Distance". Then the two-dimensional data with time series data is extended to three-dimensional data to construct a dynamic evaluation method based on vertical projection method. The difference degree and the values growth degree of evaluation index values are both considered by this model. Finally, the values and sequencing results of the evaluation objects are calculated by quadratic-weighted method. The values and sequencing results of the evaluation objects at a certain time and the overall evaluation values and sequencing results of the evaluation objects at a period of time are both obtained by this method. In order to prove the stability and effectiveness of the model in this paper,this dynamic evaluation method is used to evaluate the innovation capability of eight comprehensive economic zones in China.The data on the index system for the evaluation of innovation ability comes from China statistical yearbook, China statistical yearbook on science and technology, and the website of People's Bank of China,meanwhile, the sensitivity analysis of preference parameters to the ranking results and the comparison of other dynamic evaluation methods are discussed with this examples.The research of this paper contributes to enrich the theory and application of dynamic evaluation method.
