5.1. Descriptive Results
Table 3 presents the descriptive statistics of the data and shows that the average corporate value, measured by
Tobinq, was 2.22, much lower than 2.99 (in Bai
et al. [
16]), 2.92 (in Wei
et al. [
33]), and 2.68 (in Tian and Estrin [
19]). The latter three studies included both family and state-owned PLCs in their samples, which suggests that family-owned PLCs have much lower corporate value than do state-owned PLCs in China. Meanwhile, controlling families’ ultimate cash-flow rights averaged about 23.8%, and their ultimate control and cash-flow rights averaged 2.06, indicating that Chinese family-controlled PLCs have high ownership concentration and largely diverging ultimate control and cash-flow rights. Of the total sample firms, 70.7% had more than one large shareholder with no less than 5% ownership. On average, about 35.8% of directors were independent, much lower than that in developed Western countries. In the sample firms, top managers owned an average of only 2.1% of their companies’ shares. Only 18.0% of the CEOs were also either chairmen or vice chairmen of the board of directors, much lower than 35% when both family and state-owned PLCs were included (in Bai
et al. [
16]). This result means that Chinese state-owned PLCs much more frequently have dual CEOs and (vice) chairmen on their boards of directors.
More specifically, to derive more insightful knowledge about ultimate family-ownership structure in Chinese PLCs, we summarized yearly statistics for family-ownership structure over the sample period of 2004 to 2008.
Table 4 shows the results indicating that controlling families’ ultimate cash-flow rights decreased yearly, from 2004 to 2006, but markedly increased from 2007 to 2008. However, controlling families’ ultimate control and cash-flow rights diverged increasingly each year in the first three years, but substantially decreased in the last two years. For example, controlling families reaches their lowest average ultimate cash-flow rights of 20.3% in 2006 but the highest of 27.6% in 2008, while their ultimate control and cash-flow rights have their highest average ratio of 2.37 in 2006 but their lowest of 1.78 in 2008. Thus family ownership structure in Chinese PLCs changed substantially during the sample period of 2004 to 2008. This change predominantly tended toward the weakening divergence of control and cash-flow rights.

Table 5 shows the correlation coefficients between main variables included in regression models, illustrating that the absolute values of correlation coefficients are much smaller than 0.5 except for the coefficients among our three alternative corporate value measurements. Hence, multicollinearity does not appear to be a significant problem in this study.

5.2. Regression Results
Table 6 reports the results of fixed-effects (within) regressions of family ownership on our three corporate value measures of
Tobinq,
Tobin70, and
Tobin80. In Models 1 and 2 we used
Tobinq as the measure of corporate value, Models 3 and 4 used
Tobin70, Models 5 and 6 used
Tobin80. In all models, we included control variables (e.g.,
Firm size,
Firm age,
Firm leverage,
Tangible assets,
ROA,
Sale growth) commonly used in studies of corporate value, as well as year dummy variables and industry dummy variables.

As
Table 6 displays, when the regressions included only
Family ownership, we found no significant relationship between family ownership and corporate value (see Models 1, 3, and 5 in
Table 6). However, when we included
family ownership and
family ownership squared into the regressions at the same time,
family ownership had positive and almost significant coefficients for our three corporate value measures, and
family ownership squared had negative and significant coefficients at the 1% level (see Models 2, 4, and 6, in
Table 6). These findings indicate that in China, a nonlinear inverse-U-shaped relationship, rather than a linear relationship, occurs between family-concentrated ownership and corporate value, consistent with hypothesis 1. Using the coefficients of
family ownership and
family ownership squared from Model 4 and taking
Tobin70 as the measure of corporate value, we got the turning point of the nonlinear inverse-U-shaped relationship. On the turning point,
family ownership equals approximately 33.27%. This value implies that a positive relationship occurs between
family ownership and
Tobin70 when controlling families’ ultimate ownership is below 33.27%, the interest-alignment effect of family-concentrated ownership, but a negative relationship occurs between
family ownership and
Tobin70 when the controlling family’s ultimate ownership is no less than 33.27%, the entrenchment effect of family-concentrated ownership.
Our results are more or less consistent with previous research in Canada, family ownership was found to be negatively related financial performance (Morck
et al. [
30]). In another study, panel data on S&P 500 firms showed firm performance and family holdings to have a nonlinear but inverted-U-shape (Anderson and Reeb [
27]). Panel data on 275 German listed companies showed family ownership to be significantly and positively related with accounting performance, but slightly significantly related with market valuation through a 10%-level nonlinear relationship (Andres [
28]). Combining the evidence, we argue that low levels of family-concentrated ownership can help resolve agency problems between shareholders and managers, but high levels of family-concentrated ownership and thus outright control might allow owners to expropriate minority shareholders to maximize their own utility, especially in emerging economies, such as China’s, where legal investor protections are poor. However, our findings sharply contrast with three studies on state shareholdings in China (Bai
et al. [
16], Wei
et al. [
33], Tian and Estrin [
19]) that find a nonlinear-U-shaped relationship between state shareholdings and corporate value. Those differing results may occur mainly from different ownership state-owned and family-controlled structures in the Chinese stock market (see
Table 1). Once again, to avoid drawing murky and inconsistent conclusions, future researchers focusing on the issues of Chinese corporate ownership structure should be aware that Chinese state-owned and family-controlled companies are vastly different.
In terms of the divergence of the controlling family’s ultimate control and cash-flow rights, the
Wedge of control and ownership coefficients were negative in all regression models, as Hypothesis 2 predicts. However, only some are statistically significant (see Models 3 and 5, in
Table 6). As a whole, hypothesis 2 is weakly supported. That is, the divergence of controlling families’ ultimate control and cash-flow rights may exacerbate the expropriation of minority shareholders and thus reduce corporate value in China, which coincides with prior studies (e.g., Claessens
et al. [
3], Lemmon and Lins [
39], Lin
et al. [
11,
12], Maury [
40], Yeh [
21]).
In the context of concentrated-ownership structure, do traditional governance mechanisms play an effective governance role and affect corporate value? To answer that question, we examined the effects of four most-frequently mentioned governance variables on corporate value. As
Table 6 shows, the
Multiple large shareholders variable was positively related to corporate value in all regression models, but only significantly related to corporate value, as measured by
Tobinq (see Models 1 and 2). Overall, the results indicate that multiple large shareholders are associated with higher corporate value, consistent with previous empirical findings (Attig
et al. [
41], Maury and Pajuste [
42]). The proportion of independent directors on the boards had positive coefficients in all regression models, which is significant at least at the level of 5%. Hence, our findings strongly indicate that board independence can play an effective governance role in preventing controlling families from expropriating minority shareholders, thus improving corporate value. More specifically, our findings suggest that although the independent director system has a short history in China, it is now mature enough to play an effective governance role as intended in Chinese PLCs. In addition, we found no significant effects of management ownership and CEO duality on corporate value, indicating that the two traditional governance factors do not affect corporate value. Taken as a whole, the role of traditional internal governance mechanisms is much limited in the context of concentrated ownership (Berglöf and Pajuste [
22], Claessens and Fan [
23], Morck
et al. [
24]).
Of the six control variables, the nature log of total assets (
Firm size) was negatively associated with corporate value at the 1% level of significance in all regression models. This result corroborates previous findings (e.g., Bai
et al. [
16], Tian and Estrin [
19], Wei
et al. [
33]) and indicates that smaller firms have higher corporate value in the Chinese stock market. Similar to prior evidences,
ROA positively affects corporate value at the 1% level of significance in all regression models, suggesting that better accounting performance is associated with higher corporate market performance in Chinese family-controlled PLCs. However, our results show no signs of significant and consistent effects of
Firm age,
Firm leverage,
Tangible assets, and
Sales growth on corporate value in the Chinese stock market.
5.3. Analysis of Endogeneity of Family Ownership and Corporate Value
Our results potentially suffer from an endogeneity issue: our observed relationship between family ownership and corporate value might be the result of reversed causality. Ownership structures are firm-specific and affected by compensation plans, insider trading possibilities, and corporate takeovers (Demsetz and Lehn [
43], Demsetz and Villalonga [
44]), which indicates that firm performance/value affect the ownership structure. In our study, family ownership might be an endogenous variable. However, the argument for the endogeneity of family ownership is questionable. Many empirical findings (e.g., Andres [
28], Gugler and Weigand [
45], Holderness [
46], La Porta
et al. [
26]) suggest that ownership structures, especially large shareholder ownerships, are relatively stable over time. Hence, it seems unlikely that large family shareholders will change their ownership quickly and frequently in light of the firm’s temporary market valuation.
Despite the questionable argument of the endogeneity issue, we tested the robustness of our results by employing an IV-2SLS panel-data model; that is, fixed-effects (within) IV regressions. Specifically, the ultimate cash-flow rights of family-controlling shareholders (
family ownership) are instrumented by lagged value in all regressions.
Table 7 shows the regression results drawn by this method. After controlling for endogeneity, the inverse-U-shaped relationship between family ownership and corporate value was still significant for all three measures of corporate value:
Tobinq,
Tobin70, and
Tobin80. The results indicate that serious reversed causality may not occur between family ownership and corporate value. In other words, endogeneity of family ownership does not drive the inverse-U-shaped relationship between family ownership and corporate value drawn in this study.
