Abstract:Based on the evaluation index system of regional innovation capability and innovation environment,this paper analyzed the environmental synergy effect of the development of provincial innovation capability in China by the coupling model.Findings?show?that:①The innovation ability and the innovation environment show strong synergistic effect When the value of innovation environment benefit is less than 0.20.When the benefit value of innovation ability is greater than 0.146 or less than 0.066, the synergy effect between innovation environment and innovation ability is weak.②Our country does not have the province domain which the innovation ability and the innovation environment high quality coordinated development.Most of the eastern part of the region is lagging behind the innovation of the environment, although these areas have a strong ability to innovate, but the innovation environment can not effectively promote the ability of innovation.In the west,most of the regional innovation capability and the development of innovation environment is not harmonious, innovation ability and innovation environment are more backward.According to this,this paper puts forward some suggestions on enhancing the environmental coupling effect of the development of regional innovation capability.
