Under network environment,Technological Innovation Capability (TIC) of enterprises is influenced not only by enterprises themselves,but also by relevant ability to exchange information and communication with outside world.According to the new characteristics of enterprises TIC under network environment,the Balanced Score Card (BSC) method is introduced to analyze and evaluate the enterprise TIC,and a new enterprise evaluation index system of technological innovation is built,which conduces to acquisition and quantification of factors in the index system.Furthermore,the application of analytic network process (ANP) method works out the complex relationship between the evaluation index correlations.The model of enterprise technological innovation based on BSC-ANP method improves the accuracy of evaluation.
