Abstract:Considering the profit core target of private technology incubator (PTI), profit performance and service ability indicators are proposed to reflect the current and future profitability of PTI, then the performance evaluation index system (PEIS) of PTI can be built. Referring to the idea of CRITIC method which is to determine the weight of indicators, a combination evaluation method of weighting different evaluation methods is proposed based on refined CRITIC. Firstly, the performance of PTI is evaluated through Analytic hierarchy process (AHP), Entropy-ideal Point Method (E-TOPSIS) and Standard deviation respectively. Secondly, the vertical differences of these three evaluation values are calculated by the standard deviation method. The horizontal similarities of three evaluation values are calculated by changing the linear correlation coefficient used in the CRITIC method to the grey correlation degree. Finally, the combination weights are obtained by combining the horizontal similarity values with vertical difference values. The empirical results verify the feasibility and effectiveness of the refined CRITIC.
