Abstract: To foster innovation activities, regional innovation policy constitutes an indispensable instrument. However, the unbalanced growth model continues to exist. The lack of emphasis on policy effectiveness represents a key issue in this regard. This paper examines the causes of regional innovation heterogeneity, based on the degree of positive sentiment impact in policy documents. Analysing data from China’s four economic zones shows that policy sentiment exerts a dominant influence on innovation output. This article argues that government should adopt a positive emotion to encourage regional innovation achievements.
