Will conjugal relationship affect the corporate innovation? Empirical evidence from a-share listed family business in China

Purpose: Few studies have focused on the impact of conjugal control and non-conjugal control on the innovation capability of family firms. In the context of the relative lack of research on the relationship between family firm heterogeneity and innovation ability, this study aims to focus on the differentiated impact of husband–wife-controlled family listed companies and non-husband–wife-controlled family listed companies on their innovation capabilities, which provides empirical evidence with more Chinese institutional and cultural characteristics for the development of corporate organizational management and innovation theories. Design/methodology/approach: Taking all A-share listed family firms from 2007 to 2016 as the research sample, this paper examines the influence of spousal control on firm innovation level by empirical research method. Findings: The empirical results show that compared with non-spousal-controlled family enterprises, spousal-controlled family enterprises have significant positive effects on the level of enterprise innovation. Further studies suggest that joint management of spousal-controlled family enterprises improves the level of innovation. Authority difference of the couple will weaken the innovation capacity. However, the wife’s professional skills can promote the innovation level. Originality/value: Focusing on the characteristics of family internal structure and embedding marriage relationship in the enterprise organization, this paper investigates the influence of different characteristics of husband and wife and cooperation mode on enterprise innovation, and the conclusion enriches the theory of family business and family science, as well as provides important information reference for the stakeholder groups in the capital market.
