Abstract: A dynamic evaluation method is proposed, in order to compare multiple systems at different times. The two-dimensional data with time series data is extended to three-dimensional data. Dynamic evaluation method based on TOPSIS is put forward. The difference degree and the values growth degree of evaluation index values are both considered.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 practice, a dynamic evaluation is conducted on the independent innovation capabilities of the provinces in east China. The evaluation indicators for the regional technological innovation capacities come from Chinese statistics yearbook, Chinese science and technology, statistics yearbook, and the web site of People's Republic of China Ministry of Science and Technology which provides a database with the major indicators for the science and technology in China. It is proved that the findings of this work are practically effective. The method proposed in this study provides an idea in dealing with dynamic evaluation, and complements the comprehensive evaluation method, and facilitates the researches in related fields.

Key words: TOPSIS, dynamic evaluation method, three-dimensional data
