Synthetic Evaluation of Science and Technical Innovation Ability based on Extension

The scientific and technical innovation has become crucial factor that affect society economic growth and the social development. On establishing scientific and reasonable scientific innovation ability evaluating index system, has established synthetic evaluation element model of the scientific innovation ability using the extension evaluation method. Through calculating its comprehensive correlative degree to carry on the comprehensive quantitative analysis, the multi-index evaluation is transformed into single objective decision-making, has realized synthetic evaluation of the scientific innovation ability, overcome the shortcoming which the sole evaluation method exists. Through the empirical analysis and evaluation to China 10 provinces and cities' scientific innovation ability, has carried on the beneficial research to the scientific innovation ability evaluation method, provides a new scientific and practical method for the scientific innovation decision-making.
