Equity Entry Mode and Enterprise Performance: A Meta-Analysis

The 
choice of entry mode, especially the choice between sole proprietorship and 
joint venture, is one of the important strategic decisions for multinational 
corporations to make foreign direct investment. Although there have been a 
large number of empirical studies on the relationship between entry mode and 
enterprise performance, the existing studies have not reached a more consistent 
conclusion on the relationship between them and the influencing factors 
affecting the relationship between them. This paper selects 58 independent 
empirical studies, and uses the Meta-analysis 
method to integrate the empirical results, and obtains the comprehensive 
results that the equity entry mode has a significant impact on corporate 
performance. At the same time, the study also found that the relationship 
between equity entry mode and enterprise performance is affected by the degree 
of development of the source country and host country, enterprise size and 
other factors.

In the process of enterprise internationalization, enterprises will face the choice of entry mode. Entry mode is the cornerstone of multinational corporations' market entry strategy. In the face of the complex and changeable foreign investment environment, the rationality and effectiveness of the entry mode of overseas investment market will directly affect the performance of enterprises. Whether it adopts the new green space of the host country or the direct acquisition of the host country enterprise, or through the wholly owned hierarchical governance model or the joint venture mixed governance model, There are great differences in the resources, technology, manpower and risks that enterprises need to invest after making the choice of entry mode, so it will have different effects on the performance of multinational enterprises. In addition to the internal factors of the enterprise that will affect the performance of multinational enterprises, external factors such as the economic environment of the host country will also have an impact on the performance of overseas investment of multinational enterprises. Therefore, there is a contingency relationship between the entry mode of overseas investment market and the level of enterprise performance. What kind of entry mode enterprises adopt will have a vital impact on the success of enterprises, so that Wind and Perlmutter (1977) define entry mode as the frontier issue of international marketing [1]. Foreign direct investment is one of the important means for enterprises to enter the international market.
Many scholars at home and abroad have studied the relationship between entry mode and business performance, but many studies are based on different theories and from different perspectives. Therefore, the conclusions of the relationship between the two are not consistent, even if some studies use the same theory to explain, the conclusions may be inconsistent, or even the opposite. At the same time, the research literature on the entry mode and performance of overseas investment market is rich, which meets the objective conditions for meta-analysis. Therefore, this paper plans to use the method of meta-analysis to study. Not only the subjectivity of qualitative literature research can be avoided, but also the overall estimated results can be obtained through the quantitative integration of the existing research results, and the sources of differences between different literature research results can be found. Therefore, this study itself has important theoretical innovation significance.

The Relationship between Equity Entry Mode and Enterprise Performance
The entry mode of enterprises' foreign investment is an important research field. Stopford and wells (1972) is considered to be an early scholar to study this issue.
They summarized several entry modes of enterprise internationalization choice, but did not analyze and explain the theoretical basis of this choice [2]. The early scholars' theoretical research on the entry mode of cross-border investment mar-  [3] and the international production compromise theory of Dunning (1977) [4] were the most representative. The theory of monopoly advantage emphasizes that the decisive factor affecting the international expansion behavior of enterprises is monopoly advantage, and puts forward for the first time that the overseas investment market should take the market imperfect competition as the starting point, that is, only the market is in an imperfect state. Only then can the enterprise carry on the marginal expansion by virtue of its own monopoly advantage. The essence of internalization theory is the expansion of enterprise management and control based on ownership. It mainly focuses on the transaction costs of enterprises operating in overseas markets, and believes that the incompleteness of market information in the host country and the uncertainty of intermediate product prices will make enterprises bear higher transaction costs. As a result, multinationals can internalize transactions to reduce costs and improve corporate profitability. The theory of international production compromise synthesizes the theoretical achievements of its predecessors, and holds that the enterprise's international direct investment is determined by three basic factors: ownership advantage, internalization advantage and location advantage, and a more complete explanation and analysis of the motivation, direction and location choice of overseas investment. The early research on the choice of entry mode of overseas investment market tends to the perspective of transaction cost. Transaction cost theory shows that under the condition of imperfect competitive market, enterprises will try to minimize costs and maximize benefits in the process of internationalization. In the early stage, the people who really began to apply the transaction cost theory to the choice of entry mode were Anderson and Gatignon (1986) [5], who took the transaction cost as the main research object. On this basis, this paper constructs the analysis framework of the entry mode of enterprises' overseas investment market, and focuses on the circumstances under which multinational enterprises can choose which strategic model to maximize the rate of return on investment. In the real sense, the theory of transaction cost is put forward by Willianmson (1975Willianmson ( , 1985 [6] [7]. He points out that there is a positive correlation between the specificity of assets and the uncertainty of transaction and the degree of control of the entry mode of overseas investment market. That is, the higher the degree of specificity of assets, the more uncertain factors in trading, the more easily the agency problem of enterprises is affected, and the phenomenon of "hitchhiking" will become more and more serious. Therefore, enterprises are more inclined to choose a highly controlled mode of entry into overseas investment.
After the 1990s, the environmental uncertainty faced by multinational corpo-

The Regulating Factors of Equity Entry Mode and Enterprise Performance
Performance measurement can be divided into two categories: objective mea- performance, subjective measurement is more random. But at the same time, it may also be able to reflect some objective ways cannot observe the performance.
Therefore, we speculate that the relationship between equity entry mode and corporate performance may be affected by the way of performance measurement.
In the early research on entry mode and enterprise performance, most of them take the enterprises of the United States, Japan, Europe and other devel- Comparing the two entry modes of sole proprietorship and joint venture, there are many differences in the impact on the operation and management of the company. Woodcock and Beamish (1994) found that the performance of enterprises that choose new governance mode of greenfield to enter the host country market is better than that of enterprises that choose joint venture and other mixed governance mode, while the performance of enterprises that use joint venture mixed governance mode to enter the host country market is higher than that of enterprises that use acquisition entry mode to invest in overseas markets [12]. Pan, Li and Tse (1991) also believe that the entry mode of joint venture is higher than the operating performance brought about by acquisition [13]. Li and Guisinger (1991) takes the failure rate as the proxy variable of performance, the ship is better than that of joint venture, and the performance of joint venture is better than that of cross-border mergers and acquisitions [15]. Through empirical analysis, Zahra, Ireland and Hitt (2000) concluded that the adoption of high-control overseas investment market entry mode to enter the host country market has a significant positive effect on transnational performance [16]. Brouthers and George (2004) proposed that there is a discretionary relationship between overseas investment market entry mode and transnational performance [17]. From the perspective of transaction cost, in the case of newly-built sole proprietorship, the enterprise usually replicates its successful behavior in a foreign market, and the enterprise usually has suitable resources and assets, so the cost caused by resource demand is relatively small (Woodcock et al., 1994). Under the conditions of a joint venture, the costs of the joint venture include finding a suitable joint venture partner, losing sole control over the company's core resources (Kim and Hwang, 1992 [18], Kogut and Zander, 1993 [19]), and integrating the assets with the partner's assets, at the same time, the assets should be coordinated with the objectives and strategies of the joint venture. Therefore, the cost of a joint venture is higher than that of a sole proprietorship. From the perspective of management control, the cost of operation and management of a joint venture is higher than that of a wholly-owned enterprise because of the shared ownership, whether from the perspective of the initial negotiation on the right of control or in the later stage of business management (Beamish and Banks, 1987 [20]; Killing, 1983 [21]). In order to manage effectively, the joint venture must take a certain period of time to establish an appropriate management system, and requires the attention of the management of both sides. On the contrary, the newly-built sole proprietorship enterprise makes it have full control from the establishment to cancellation of the enterprise (Hill et al., 1990), which can also avoid the conflict of interests or mode of operation of both parties, and the performance should be relatively good [22]. Transaction cost theory and internalization theory believe that joint venture is an effective way to organize overseas markets, because it helps to solve the opportunism and uncertainty (Bearnish & Banks, 1987) caused by international operation. Some scholars believe that having a cooperative investor in the host country is actually a mechanism, which helps to reduce the risk of institutional conflicts between overseas subsidiaries and the host government, and also helps to eliminate outsider disadvantages (Zaheer, 1995) [23]. However, Vanhonacker (1997)  Open Journal of Social Sciences thority to establish, manage and protect production processes and processes to achieve cost savings [24]. Therefore, we believe that different ownership structure may affect the relationship between entry mode and performance.
The environment of the host country is one of the factors that must be consi-

Results of Heterogeneity Test and Meta Integration
When the heterogeneity included in the study is evaluated by Q test and statistics, if p > 0.1 and ≤50%, it shows that there is no obvious heterogeneity in the sample effect value, so the fixed effect model should be adopted. On the contrary, the random effect model should be adopted. In this study, 97 effect values were included for analysis, because p < 0.1, so the random effect model was used.
Through the integration of the effect values, the results are as follows: The weighted average effect value of uncorrected reliability is −0.03 (95% CI:  [25]. At the same time, the equity entry mode has more resources than the non-equity entry mode, and the enterprise income may not completely cover the enterprise input in the short term, so there is a negative correlation between the equity entry mode and the enterprise performance.

Publication of Bias Assessment Results
There is evidence that statistically significant studies are more likely to be published, while some studies that do not have significant statistical results are reduced to "drawer files". This tendency leads to the use of published analysis to distort the true effect. Especially when the sample size of the study is small (Hedges, 1984) [26]. At present, the most commonly used bias detection methods are inverted funnel diagram method and insecurity factor method, but both of them cannot quantitatively detect publication bias. Beg method and Egger rule can be used to quantify the bias. In this paper, the classical Egger method and Begg method are used to test. The P value of Begg test was 0.545 > 0.05, indicating that there was no obvious publication bias, while the P value of Egger test was 0.917 > 0.05, which also suggested that there was no obvious publication bias.

Regulation Effect Analysis
In this paper, we do not add the classification variable of the host country in model 1. In model 2, we add whether the host country is a classification variable of emerging economies. The results are shown in Table 1.
Comparing the results, we can find that the type of performance measurement in model 1 and model 2 has no significant effect on the relationship between equity  entry mode and enterprise performance. This shows that although the objective measurement of performance is relatively accurate, subjective measurement of performance has a certain randomness, but no matter which performance measurement method is used will not affect the relationship between equity entry mode and enterprise performance.
Whether the country of origin of the sample enterprise is an emerging economy or not has a significant negative regulatory effect on the relationship be-

Conclusion
This paper systematically codes 58 empirical literatures on the relationship between entry mode and enterprise performance from 1997 to 2018. By using the method of meta-analysis, this paper makes a systematic analysis of the relationship between equity entry mode and enterprise performance and the factors that may affect the relationship between them, and draws the following main conclusions: in general, there is a significant negative correlation between equity entry mode and enterprise performance. Compared with the non-equity entry mode, the equity entry mode invests more resources, and the enterprise performance may not be able to cover the resources invested in the short term. At the same time, some enterprises choose foreign direct investment, often in order to seek the long-term survival and success of enterprises, so the maximization of profits in the short term may not be the main goal of enterprises. Although the conclusion of the integration analysis is that there is a significant negative correlation between the equity entry mode and the performance, the heterogeneity test results in the integration analysis are significant, indicating that there is still obvious heterogeneity. That is to say, there are important regulatory variables that form the difference between equity entry mode and performance. Therefore, this paper further makes a meta-regression analysis of the regulatory variables which may affect the relationship between the two. From the results of meta-regression analysis, we can draw the following conclusions: the relationship between entry mode and performance is regulated by the source country type, ownership structure, company size and host country type of the sample enterprise. These factors have a significant negative impact on the relationship between equity entry mode and enterprise performance.

Limitation
We mainly analyze the overall effect of entry mode on enterprise performance. Although in the process of analysis, this paper follows the previous practice and selects the relevant empirical research from the first-class journals. However, this does not completely rule out the possibility that there may be some highly relevant and important theoretical research in journals other than these journals. At the same time, this paper is based on the existing empirical research is mainly based on the ownership of the entry model, other entry models based on franchise or license management may also be related to enterprise performance. However, it is not discussed in this study, which can become a direction of future research. You will always be the driving force for me to move forward.
