Abstract: Faced with being “locked at the low-end” and other practical difficulties, many industrial clusters in China have the top priority of enhancing their network innovation ability so as to realize their sustainable development and upgrading, and strengthening network learning and the effect of learning is an effective way for these clusters to form the cluster network innovation ability. According to the theory of social psychology, behavior is a kind of outward manifestation of psychological perception. Thus it is not enough to study the effect of network learning only from such perspectives as the physical network structures of industrial clusters formed on the basis of the corporate economic transaction relationships in the clusters or the corporate interactive learning behaviors, it is also necessary to analyze deeply the psychological perception hiding behind the corporate learning behaviors in the clusters, i.e., the psychological contracts of the clustered enterprises. Therefore, taking the theoretical explanations and the factor analysis of the psychological contracts existing between the clustered enterprises as a starting point, this paper puts forward the concept model and research hypothesis of the psychological contracts of the clustered enterprises, the trust and the effect of network learning. Through data collection and empirical analysis of the conceptual models, this paper proposes some policy suggestions to improve the network learning effect of the industrial clusters from the perspective of psychological contracts of the clustered enterprises.

Key words: industrial cluster; psychological contract; trust; network learning effect
