The research of the RTIE performance by using the projection pursuit model

Since the regional technology innovation system is an open system that is away from equilibrium, nonlinear, layered and fluctuant, and has the characters of ecosystem, we will regard the technology innovation system as a technology innovation ecosystem. Based on the concept of regional technology innovation ecosystem (RTIE), we set up the evaluation indicator system to analysis the performance of input and output of technology innovation in 30 Chinese regions by using projection-pursuit model. As a result of the statistical technology´s overcoming the impact of abnormal points, we get better evaluation conclusion. So it is a reasonable method for projection-pursuit model to evaluate the regional technology innovation ecosystem performance.
