CHAPTER INTRODUCTION ng 1.1 Problem statement hi ep The economic reforms known as DOIMOI in 1986 helped Vietnam’s Economy have a high jump whereby it was converted from a centrally planned w n economy to a market economy In this reform, the equitization process of state lo ad owned firms in Vietnam was proposed in 1991 and was launched in 1992 State sold y th a part of their shares in firms to public investors with the focus to improve their ju performance As a result, these firms’ ownership structure is a mixture of many yi pl components as state, institutions, foreign, individual… al n ua The role of state ownership in firm’s financial performance has been the n va interesting subject of ongoing debate between economic researchers Though there fu are many studies which conduct to the impact of ownership on firm performance, ll lack of in-depth researches have been conducted to Vietnamese context (Le, 2015; m oi Phung & Mishra, 2016) It originates from the reason that Vietnamese economy is nh at not really similar to other economies because Vietnam is in group of developing z countries with transforming economy Most previous researches in Vietnamese z ht vb context have investigate the effect of state ownership structure on firm performance, jm however number of researches which find the correlation of state ownership and k financial decisions as leverage and investment is minority There is limited empirical gm l.c evidence on the effect of state ownership on level of debt and level of investment in Vietnamese firms although the role state ownership is important in transforming om economy as Vietnam Therefore, to investigate the impact of state ownership and an Lu firm financial decisions on firm performance is main purpose of this thesis n va Some previous studies have examined the correlation of ownership and firm’s state ownership, leverage, investment, firm performance and other corporate governance factors It is difficult to evaluate separately the impact of state ownership which has simultaneous correlation with other factors For evidence, if the impact Page ey interpret their simultaneous relation, especially the endogenous problem among t re financial characteristics However, the limitation of empirical evidence can fully of state ownership on firm performance is positive, it may be caused by the fact that in the case of favorable business environment, firm with higher level concentration t to of state ownership approach to bank credit easier tend to expand scale of production ng process and create more benefits Since, researches may see erroneous result of hi ep studies because of endogeneity problem This limitation is my motivation for this research As a result, in order to solve the problem statement mentioned above, this w thesis will concentrate to analyze the impact of state ownership, leverage and n lo investment on firm performance and test the hypothesis about two-way correlation ad between leverage and investment y th ju 1.2 Research objective yi pl The objective of this thesis is to analyze the impact of state ownership, al n ua together with investment, leverage level and corporate governance on the firm n va performance There are two main objective, as following: oi m performance ll fu - Testing the causal relation between state ownership concentration and firm at nh - Analyzing the potential impact of state ownership concentration together with leverage and investment on firm performance z z - Analyzing the potential two – way impact of leverage and investment k jm ht vb 1.3 Research question l.c gm In order to resolve the above objectives, I have reflected two research questions: (i) Does state ownership concentration, leverage and investment affect to firm n va (iii) How does the two – way effect of leverage and investment? an Lu (ii) How does state ownership concentration influence effect on leverage? om performance? This thesis uses data collected from audited financial statement and annual reports of 269/307 listed firms in Hochiminh Stock Exchange (HOSE) in the period 2010-2015 The dropped firms cover firms violated the securities regulations, Page ey t re 1.4 Research scope merged, lacked data and financial firms Financial firms include banks, securities firms and insurance firms are not covered in this thesis Finally, the database cover t to 1614 observations of 269 firms in years ng 1.5 The thesis structure hi ep After the first chapter, the thesis will continue with the other four chapters which can briefly be presented as follows: w n lo - Chapter is the presentation of the theoretical and empirical evidences ad related to the relationship of state ownership concentration, firm performance and y th ju other firm characteristic Conceptual framework is also illustrated in this chapter yi pl - Chapter presents the research methodology in which the formulation ua al model, data measurement and formulation hypothesis Furthermore, econometric n technique will be introduced va n - Chapter contains the simple statistics and regression analyses and fu ll discusses the results with the arguments from the reviewed literature m oi - Chapter is the formulation of the generation finding and discussion The nh at implications are proposed for the policy purposes Discussions of limitation and the z potential improvement for future studies are included z k jm ht vb om l.c gm an Lu n va ey t re Page 4.2.3 The correlation between leverage and investment This section tests the two-way effect of leverage and investment by using t to equation (3) and (4) The above hypothesis considers that investment affect positive ng to leverage but at invert side, leverage is expected to reduce level of investment in hi ep firms The effect of leverage on investment w Column (3), (7), (11) of table 4.5, 4.6, 4.7 demonstrate the impact of leverage n lo on capital expenditure – a proxy of investment While column (3) shows the effect ad of total leverage, column (7) & (11) demonstrate the influence of long-term and y th ju short-term leverage respectively yi The result of regression shows that short-term leverage affect negatively to pl ua al investment All of tables demonstrate negative coefficient of short-term leverage in the equation of investment (model 3) significant at 1% level which implied that the n n va firms with high level of short-term debt seems tend to underinvestment ll fu On the contrary, the effect of long-term debt on investment is positive Still oi m significant at 1% level, the regression of model (3) which uses long-term leverage nh as a proxy of leverage show positive coefficient It implies that firms with higher at level of long-term debt have more investment projects than others with lower level z z long-term debt In general, firms usually use long-term debt as a financing resource vb is positive k jm ht of investment project As a result, the relationship of long-term debt and investment gm The regression of model (3) which use total leverage as proxies of leverage l.c show an similar result with result of short-term leverage one Table 4.5 and 4.6 show om the positive coefficient of total leverage significant at 1% level when result of table an Lu 4.7 is positive but insignificant This result is consistent to the research of Aivazian, Ge & Qiu (2005) which investigate the impact of leverage on investment in listed n va Canada firms and support explain of Myer (1977) about agency problem of ey t re bondholder and shareholder The effect of investment on leverage The result of regressions of model (4) – leverage equation – are presented at column (4), (8), (12) of table 4.5, 4.6, 4.7 The result is significant in table 4.5 but insignificant in table 4.6 and 4.7 Page 44 The regressions showed in table 4.5 encourage the hypothesis about the positive effect of investment on leverage The coefficient of investment in the t to regression of total, long-term and short-term leverage significant at 1% level This ng result supports pecking order theory and implies that when firms act investment hi ep project, their priority is using internal cash flow As a result, internal cash flow of firms will reduce sharply In order to supplement the finance resource, firms will w increase debt, both long-term and short –term n lo 4.3 Chapter remark ad y th This chapter uses three – stage least square to investigate the simultaneous ju correlation among state ownership, firm performance, leverage and investment yi pl Consistence with the research of Le (2015), the study found non –linear with U- al ua shape impact of state ownership concentration on firm performance Specially, the n result of this study also found the negative effect of both leverage and investment va n on firm performance In additional, this study also demonstrate non-linear effect of ll fu state ownership on leverage but while it affects to long – term leverage with U- m oi shape, the impact of it on short-term is invert U- shape The result also encourage at nh the hypothesis about two – way effect of leverage and investment While investment z affect positively to leverage, in invert side, increasing level of debt in firm may tend z k jm ht vb to decrease level of firm investment om l.c gm an Lu n va ey t re Page 45 CHAPTER CONCLUSIONS AND POLICY IMPLICATION t to ng hi Based on the empirical finding accomplished from previous chapter, this ep chapter give a summary of conclusions and draw some policy implications Furthermore, the chapter also shows this thesis’s limitations and further research on w n the topic in the future lo ad 5.1 Conclusion y th ju Using 1614 observation from 269 listed firms in Hochiminh Stock Exchange yi (HOSE) in the period 2010-2015, this thesis is accompanied to study these following pl ua al gap in the context of Vietnam First, the effect of state ownership on ROA/ Tobin’ Q /Z-score which are proxies of firm performance Second, the correlation between n n va state ownership and financial decisions such as leverage and investment Third, the ll fu two-way effect between leverage and investment In addition, a newly econometric oi m technique, three – stage least square, is applied to resolve endogeneity problem at investment nh among variables: state ownership concentration, firm performance, leverage and z z The table 5.1 demonstrates result of testing these hypothesis which vb anticipated at previous chapter The finding supported the hypothesis which ht k jm expected about U-shape relationship between state ownership and firm performance gm In additional, it also encourage hypothesis 3, 5, which related to the negative effect l.c of debt on firm performance and the two-way impact of debt and investment om However, the result of regressions just encourage partially to the hypothesis When an Lu the finding supports the non – linear correlation of state ownership and leverage, it does not confirm the invert U-shape relation Finally, the study does not support the n ey t re because the regressions show the negative effect of firm investment on firm va hypothesis predicted that firm investment affect positively to firm performance performance Page 46 Table 5-1 Summary of results Hypothesis Empirical result t to H1: Whether there exist a U-shaped relationship between Supported state ownership and performance of Vietnamese listed firms ng hi ep No supported H3: The effect of debt on performance is negative Supported H2: Firm investment affect positively to firm performance w H4a: The relationship of state ownership and leverage is non Supported - linear H4b: The relationship of state ownership and leverage is No supported inverted U-shape n lo ad ju y th H5: Leverage affect negatively to investment Supported yi pl H6: Investment affect positively to leverage Supported n ua al n va 5.2 Policy implications ll fu The empirical research has given some finding in the correlation among state oi m ownership concentration, firm performance and financial decisions Based on the at policy makers nh research result, some policy implications are recommended for the firms and the z z First, the result of this study presents the strong effect of highly concentrated vb jm ht ownership on firm performance in Vietnamese emerging market where system of shareholder protection is inefficiency As a result, policy maker should improve k gm corporate governance mechanisms and revise law to support other minority l.c ownership avoid the harmful behavior of blockholders in firms Furthermore, though om the finding of research encouraged the hypothesis about the U-shape and an Lu demonstrate positive influence of state ownership concentration on firm performance, it does not mean that state should continuous high level of holding Seconds, observation from this research shows the relationship among state ownership, investment and firm performance While state ownership concentration Page 47 ey performance, the problem related to corporate governance may eventually raise t re Therefore, if state maintain high level of concentration in firms to support firm n performance is due to political connection rather than improvements in efficiency va share in firms The positive effect of state ownership concentration on firm affect positively to level of investment in firms, the influence of investment on firm performance is negative (rejected hypothesis2) It can be suggested that investment t to project seems not efficient Therefore, firms should be careful in the decisions of ng new investment projects that can squander financial resource and increase pressure hi ep of debt (hypothesis is supported) Firms may deliberate about feasibility, efficiency and cost of project before decide the financial resource of project w Finally, the research result encourage the hypothesis which expected the n lo negative correlation between leverage and firm performance This is a strong ad evidence show the inefficiency of using debt in Vietnamese firms In reality, long – y th ju term leverage affect positively to firm performance while the relationship of it and yi short-term leverage is negative As a result, the effect of total debt on firm pl ua al performance is negative due to the main debt resource of Vietnamese firms comes from short-term debt In order to resolve this problem, Vietnamese firms should find n n va the methods to transfer leverage from short – term to long – term ll fu 5.3 The limitation and further research m oi Though some various contributions have been considered, some limitations z explored in-deeply at nh are still contained in this thesis unavoidably and other related problems can also be z First, the period of this study’s data is relatively short, only six year from vb jm ht 2010 to 2015, which may affect to the significance of examining Furthermore, k because of these obstacles relating to collecting firm’s financial information due to gm the inefficiency of law to force all firm to provide correctly reports, there is a lack l.c of some values in the data Consequently, the result of research may face to the bias om In additional, the tight monetary policy of State Bank may distort to ability to access an Lu the credit resource tend to affect to leverage and investment of firms Second, a weak point of this study may be testing only listed firm In reality, Page 48 ey firms with financial indicators under standards t re ownership concentration on firm performance and financial decision, especially on n a result, it may be argued that this research cannot assess fully the influence of state va firms which listed in Stock Exchange have get standards of financial indicators As Based on the limitation analysis, further research can go ahead with large data which can cover both listed and unlisted firm in longer time period Furthermore, it t to can be increased the significant of research’s result when further researches can ng apply more than one econometric method hi ep w n lo ad ju y th yi pl n ua al n va ll fu
