Abstract

Purpose

As literatures argue that managers’ personalities will affect both corporate governance structures and corporate performance, the correlation between them is a mixed result. The purpose of this paper is to separate different routes leading to the mixed correlation, and name the separated routes as regime effect and signal effect.

Design/methodology/approach

By theoretical analysis, the authors list three routes leading to the correlation between corporate governance and corporate performance. Routes 1 and 2 show that governance can directly and indirectly change the performance; while route 3 shows that both the governance and performance are results of managers’ personalities, and the governance has no influence onto the performance, which means the correlation led by route 3 is fake. By design a new econometric methodology, this paper separates the mixed correlation between corporate governance and performance, and names the correlation led by routes 1 and 2 as the regime effect and the correlation led by route 3 as signal effect.

Findings

By an empirical research on Chinese listed corporates, the authors find that the correlations between Chinese listed corporates’ market value and main corporate governance factors can be separated into regime effects and signal effects; and the authors also find that some factors (Share of Institutional Investors, Share of Real Controller and the Squared, Dummy of Identical CEO and Chairman, Ownership Concentration) only show regime effects, some factors (Separating Extent of Ownership and Controlling Right, Dummy of Provincial State-Owned Firms) only show signal effects, and some factors (Dummy of Republic State-Owned Firms, Scale of Board) show both. What’s more, the authors find out an interesting result that the state-owning has no negative regime effect on China SOEs’ performance but very significantly negative signal effect; in this paper, the authors suggest that this means the key negative factors of Chinese SOEs is not state-owning ownership structure but the managers’ corruption.

Practical implications

As only the factors with regime effects can directly and indirectly affect corporates’ performance and the factors with signal effects show that there’re some managers’ personalities affecting both the governance and performance, the separation method in this paper can help shareholders knowing which governance factors will be helpful to improve the performance and which others will show managers’ hard-working or corruption intention.

Originality/value

Separate the regime effect and the signal effect from the correlation between corporate governance and performance.
