Analysis of Multinational Builders’ Corruption Based on Evolutionary Game from the Perspective of International Reputation
[ad_1]
1. Introduction
To maintain a good international engineering reputation, it is crucial to crack down on engineering corruption through measures such as strengthening supervision, standardizing market order and improving the moral quality of enterprises and individuals. This study aims to explore the relationship between international engineering reputation and engineering corruption, identify gaps in current research and propose future research directions and suggestions. Through in-depth research, we hope to provide a scientific basis and methodological guidance for addressing the problem of international engineering corruption and promoting sustainable multinational cooperation.
2. Literature Review
2.1. International Corruption
International engineering corruption is a complex issue influenced by a multicultural background, leading to fundamental changes in the corruption network’s mechanism. Social relations have transformed into international relations, legal systems have shifted to international systems, organizational structures have joined multinational bodies and diverse cultures are in play. Consequently, the study of international corruption has increasingly become the focal point for domestic and foreign scholars, particularly in examining the main actors in corruption, legal systems and political cultures as basic mechanisms of corruption. Research on the impact of international reputation on international project corruption primarily centers on three key aspects: the authority of country in corruption cases, the role of legal systems in curbing corruption, and the root causes of corruption.
Indeed, the studies mentioned above primarily focus on the relationship between law, discourse power and data in addressing corruption. However, there is a significant gap in research regarding transnational corporations and their specific corruption behaviors. To promote sustainable development within international engineering corporations, it is crucial to investigate the actual corruption behavior of cross-cultural subjects within these corporations. Such research could provide a more in-depth understanding of the unique challenges facing multinational companies and identify effective strategies for combating corruption in this context. It is essential to develop a comprehensive approach that considers the cultural, organizational and regulatory factors that contribute to corruption within these organizations. Only by examining the issue of corruption in multinational corporations comprehensively can we establish effective anti-corruption measures that genuinely promote sustainable development.
2.2. Game Theory
3. Model Hypothesis and Construction
3.1. Model Assumptions
It is hypothesized that when the general contracting company and the supervisory company possess adequate management and supervision capabilities and the general contracting company adopts a strict management strategy, the supervisory company chooses a supervision strategy and the subcontracting company opts for a non-bribery strategy, both the supervisory company and the subcontracting company will benefit from policy incentives and gain positive international reputation. Conversely, if the supervisory company chooses a non-supervision strategy and the subcontracting company chooses a bribery strategy, it will result in the general contracting company incurring losses in terms of project quality and international reputation.
It is hypothesized that if the subcontracting company chooses a bribery strategy, the default target of bribery will be the supervisory company. However, if the supervisory company selects a supervision strategy, it will be considered as refusing to accept bribes. On the other hand, if the supervisor chooses not to monitor the strategy, it will be considered as accepting bribes.
It is hypothesized that when the Subcontracting company chooses a bribery strategy, the success of the bribery will only occur when the general contracting company adopts a loose management strategy and the supervisor opts for a non-supervision strategy. If any other combination of strategies is chosen, the corruption attempt will be considered a failure.
This study focuses on the game relationship between different companies in a particular project. For example, we assume a company’s international reputation is 10. Before the project, the company’s international reputation is known within the industry and is unrelated to G1, G2, or G3. When a company needs to complete a project and join it, the company will be assigned one of three identities. If the company is the general contracting company, in the three-party game environment of the project, G1 will equal 10. If the company is the supervisory company, in the three-party game environment of the project, G2 will equal 10. Similarly, if the company is the subcontracting company, in the three-party game environment of the project, G3 will equal 10.
3.2. Model Construction
3.2.1. General Contracting Company
The pure strategy set available for the general contracting company consists of two options: strict management and loose management. The probability of choosing the strict management strategy is denoted by x. If the general contracting company selects the strict management strategy, it will incur a cost, B1, associated with strict management, but also gain an income, G1, from international reputation. Conversely, if the general contracting company chooses the loose management strategy, it will not incur any strict management costs, but will still obtain the same international reputation income G1.
If the general contracting company selects the strict management strategy, it will award C1 and C2 to the supervisor for choosing the supervision strategy and the subcontracting company for selecting the non-bribery strategy, respectively. However, if the supervisor chooses the non-supervision strategy and the subcontracting company opts for the bribery strategy, they will be penalized with D1 and D2, respectively. The total contractor’s return on normal completion of the project is denoted by A1.
3.2.2. Supervisory Company
The pure strategy set available to the supervisory company comprises two options: one is to implement supervision and the other is to not implement it. The probability of selecting the supervision strategy is denoted by y. In the event that the supervisory company chooses to implement supervision, it incurs a supervision cost, B2, but also gains the benefit of a positive international reputation, denoted by G2. Alternatively, if it chooses not to implement supervision, it avoids incurring the cost of supervision, but does not gain any international reputation benefits. Assuming that the supervisor chooses the non-supervision strategy and the subcontracting company chooses to adopt the bribery strategy, the bribe revenue obtained by the supervisor is equal to the bribe cost E borne by the subcontracting company. The supervisor’s income in the absence of any irregularities is A2.
3.2.3. Subcontracting Company
The subcontracting company’s pure strategy set consists of two options: one is to engage in bribery and the other is to refrain from bribery. The probability of selecting the bribery strategy is denoted by z. If the subcontracting company chooses the bribery strategy and the bribe is successful, it will not incur any construction cost B3 but will bear the cost of the bribe E. However, if the bribery attempt fails, the subcontracting company will still have to pay the bribe cost E and additionally incur rectification cost E2. On the other hand, if the subcontracting company chooses the non-bribery strategy, it will earn income from a positive international reputation, denoted by G3, but will have to pay the construction cost B3. The subcontracting company’s return from normal completion of the project is represented by A3.
3.3. Replication Dynamic Equation Construction
The dynamic replication equation in evolutionary game theory has a significant physical meaning. This mathematical model provides a framework for understanding how the frequencies of different strategies change within a population over time. By using mathematical equations to describe the spread and evolution of strategies, it allows researchers to analyze and predict the dynamics of strategic behavior within a population. This is essential for gaining insights into the long-term outcomes and stability of different strategies in competitive or cooperative settings.
: This formula represents the rate of change of individuals choosing strategy i in the game population at time t. represents the payoff for choosing strategy i; represents the average payoff for the game population; and represents the proportion of individuals choosing strategy i within the population.
When , , choosing strategy i results in a higher payoff than the average payoff for the game population, leading to an increase in the number of individuals choosing strategy i at time t.
When , , choosing strategy i results in a lower payoff than the average payoff for the game population, leading to a decrease in the number of individuals choosing strategy i at time t.

4. Model Solving
Combined with the special characteristics of the building industry, the behaviors of all three parties have a high impact on the quality of the project. In the case of subcontracting company choosing no corruption, in order to guarantee the quality of the project, the strict management of general contracting company and the supervision of the subcontracting company are also necessary factors for the whole project. As such, the equilibrium point (1,1,0) is the only solution in the context of the actual situation. The other equilibria make sense when the quality of the project is ignored, but this result is obviously subject to greater danger.
A stable solution in evolutionary game theory must possess two key properties. Firstly, it must be resilient to minor perturbations. Secondly, under bounded rationality, if a player’s strategy changes with uncertainty, the solution should have the ability to bring x back to a stable point. Mathematically, using the general contracting company’s model as an example, these two properties can be expressed as the replicator dynamic equation being equal to zero and the first derivative of the replicator dynamic equation being less than zero.
In other words, if the replicator dynamic equation is equal to zero, it means that the system has reached a steady state where no player has an incentive to switch strategies. On the other hand, if the first derivative of the replicator dynamic equation is less than zero, it indicates that the system will return to the steady state even if a player’s strategy changes with uncertainty.
and : These two properties are crucial for ensuring the stability of the outcome in evolutionary game theory. By analyzing these properties, we can determine whether a solution is stable or not and how it will respond to small changes in strategy.
4.1. Strategic Balance Point Analysis for General Contracting Company
The third and fourth equations in Formula (16) represent the intersection points of the same plane with the y-axis and z-axis, respectively. This plane is the third part of Formula (5).
-
In y * < y < 1 and z < z * < 1, the value of F (x) increases as y increases and z decreases. In the case of x = 0, if the first derivative of F (x) is less than zero, it means that the policy stability point selects the loose management strategy for the general contracting company.
-
In y < y * < 1 and z * < z < 1, the value of F (x) decreases as y decreases and z increases. In the case of x = 1, the first derivative of F (x) is less than zero, indicating that the policy stability point selects the strict management strategy for the general contracting company.
Inference 1: The probability of the general contracting company selecting the strict management strategy is positively correlated with various factors. These factors include the penalty D1 imposed by the general contracting company on the supervisory company for choosing the non-supervision strategy, the penalty D2 imposed by the general contracting company on the subcontracting company for choosing the non-supervision strategy, and the international reputation income G1 gained by the general contracting company for choosing the strict management strategy.
Furthermore, there is a negative correlation between the management cost B1 associated with implementing the strict management strategy by the general contracting company, the reward C1 offered by the general contracting company for choosing the supervision strategy and the reward C2 offered by the general contracting company for choosing the non-bribery strategy by the subcontracting company.
4.2. Strategic Balance Point Analysis for Supervisory Company
The third and fourth equations in Formula (19) represent the intersection points of the same plane with the x-axis and z-axis, respectively. This plane is the third part of Formula (10).
- 3.
-
In x * < x < 1 and z < z * < 1, the value of F (y) increases as x increases and z decreases. In the case of y = 1, if the first derivative of F (y) is less than zero, it means that the policy stability point selects the supervision strategy for the supervisory company.
- 4.
-
In x < x * < 1 and z * < z < 1, the value of F (y) decreases as x decreases and z increases. In the case of y = 0, if the first derivative of F (y) is less than zero, it means that the strategy stability point is for the supervisor to choose the non-supervision strategy.
Inference 2: The probability of the supervisory company selecting the supervision strategy is positively correlated with several factors. These factors include C1, which represents the penalty imposed by the contractor on the supervisory company for choosing the non-supervision strategy, and G2, which signifies the international reputation income gained by the supervisory company for choosing the supervision strategy.
Conversely, the probability of the supervisory company opting for the supervision strategy is negatively correlated with the bribery cost E incurred by the subcontracting company and the supervision cost B2 associated with the supervisory company choosing the supervision strategy.
4.3. Strategic Balance Point Analysis for Subcontracting Company
The third and fourth equations in Formula (22) represent the intersection points of the same plane with the x-axis and y-axis, respectively. This plane is the third part of Formula (10).
- 5.
-
In x * < x < 1 and y * < y < 1, the value of F (z) increases as x increases and y increases. In the case of z = 0, if the first derivative of F (z) is less than zero, it means that the strategy stability point is for the subcontracting company to choose the non-bribery strategy.
- 6.
-
In x < x * < 1 and y < y * < 1, the value of F (z) decreases as x decreases and y decreases. In the case of z = 1, if the first derivative of F (z) is less than zero, it means that the strategic stability point selects the bribery strategy for the subcontracting company.
Inference 3: The probability of the subcontracting company choosing the bribery strategy is negatively correlated with various factors. These factors include the rectification cost associated with the subcontracting company’s failure in bribery, the international reputation income G2 gained by the subcontracting company for choosing not to bribe, the penalty D2 imposed by the general contracting company for the subcontracting company choosing to bribe and the reward C2 offered by the general contracting company for choosing not to bribe.
Furthermore, the probability of the subcontracting company selecting the bribery strategy is positively correlated with B3, which represents the construction cost when the subcontracting company does not engage in bribery.
4.4. Stability of Strategy Evolution
Inference 4: When the three parties involved prioritize international reputation, denoted as G1 > B1 + C1 + C2, G2 > B2 and G3 > B3, the equilibrium point is (1,1,0). This equilibrium point, signifying strict management, supervision and a lack of bribery, stands as the sole evolutionary equilibrium point. This observation suggests that the project as a whole can establish a more favorable autonomous environment when overseas engineering groups place significant emphasis on corporate culture and employees exhibit a strong sense of patriotism and collective honor.
Inference 5: When E2 > B3, the equilibrium point must lie between (0,0,0), (0,1,0), (1,0,0) and (1,1,0). This implies that the subcontracting company can effectively deter the evolution of the bribery strategy. Consequently, in the case of large scale and complex international corporations such as bridge companies, the subcontracting company is often unwilling to choose bribery due to the potential risks and high-quality costs involved. On the other hand, in the case of low-tech and low-quality cost corporations, the general contracting company can increase the cost of corruption through punitive measures during quality supervision to discourage their choice of bribery strategies.
5. Simulation and Sensitivity Analysis
5.1. Analysis of the Sensitivity of the Reputation of the General Contracting Company to Corruption
To analyze the impact of changes in international reputation parameters on the decision-making of the three parties, let us set G1 = 10, 30, 50. We will examine how the general contracting company’s international reputation influences the decision-making process.
5.2. Analysis of the Sensitivity of the Reputation of the Supervisory Company to Corruption
Furthermore, as the supervisory company pays more attention to its own international self-reputation, it prolongs the time for the general contracting company to adopt a strict management strategy. This excessive supervision may stimulate the inertia of the general contractor, making it less likely to choose the strict management strategy. Additionally, the international reputation of the Supervisory company has little influence on the bribery behavior of the subcontracting company. Thus, when selecting international corporations, we should choose a general contracting company with a high international reputation, while ensuring that the international reputation of the supervisory company is inferior to that of the general contractor. A supervisory company with a high international reputation may not be conducive to promoting the strict management strategy of the general contracting company and inhibiting the bribery strategy of the subcontracting company.
5.3. Analysis of the Sensitivity of the Reputation of the Subcontracting Company to Corruption
6. Conclusions
Based on the context of international engineering, this study develops a game model involving the general contractor, supervisory company and subcontracting company to investigate the impact of international reputation on project corruption. Through sensitivity analysis, the study explores the sensitivity of international reputation. The simulation results reveal the following findings. (1) When the general contracting company possesses a high international reputation, it contributes to the overall cultural autonomy of the project. This effectively inhibits corruption and encourages the general contracting company to adopt strict management strategies. (2) If the supervisory company has a high international reputation, it hinders the general contracting company’s choice of strict supervision strategies. This stimulation of inertia in the general contracting company is detrimental to overall project management. Additionally, as the international reputation of the supervisory company increases, the marginal effect of their chosen supervision strategy gradually diminishes. (3) As the international reputation of the subcontracting company improves, it more effectively curbs corruption and prompts the subcontracting company to quickly adopt non-bribery strategies. (4) Higher construction costs accelerate the subcontracting company’s inclination towards bribery strategies. Conversely, higher rectification costs, bribery penalties and rewards for integrity facilitate corruption control.
This study examines the different impacts of international reputation in the context of the cooperation perspective of multinational corporations, and the results can provide some insights into the governance of international corrupt practices.
Firstly, it is crucial for international general contracting companies to prioritize their international reputation. By placing importance on their international reputation, these companies can help curb corruption within subcontracting companies and encourage supervisory companies to implement stricter supervision strategies. This in turn promotes the development of all project participants in a positive direction.
Secondly, actively guiding and rewarding honesty within subcontracting companies and supervisory companies in corruption and supervision can help reduce the initial probability of corruption. In cases where infrastructure construction projects have low costs, subcontracting companies may be inclined towards bribery due to the relatively low cost of engaging in corrupt practices. Therefore, increasing penalties for corruption within subcontracting companies is necessary. Additionally, imposing high rectification costs on subcontracting companies can effectively deter corruption. Furthermore, as subcontracting companies tend to prioritize their interests over project quality due to the limited impact of reputation factors, it is important to emphasize the significance of project quality.
Thirdly, it is important to recognize that a high international reputation of the supervisory company may lead to complacency and ineffective management by the general contracting company. In such situations, enhancing third-party supervision can be beneficial, as effective third-party supervision can assist the general contracting company in successfully completing the project and curbing bribery within subcontracting companies.
Fourthly, strengthening the dominant position of the general contracting company and considering the supervisory company as an auxiliary role in joint project management can yield maximum benefits. Strengthening the connection between the general contracting company and the supervisory company not only effectively curbs bribery but also enhances the reputation of the supervisory company through the excellent international reputation of the general contracting company.
Moreover, it is important to emphasize political learning in the training of management personnel within the general contracting company, supervisory company and subcontracting company. This helps strengthen legal awareness in all construction stages and decision-making processes while also considering the significance of international reputation, thereby ensuring the smooth progress of the project. Additionally, the adoption of advanced high-tech technology can reduce labor requirements, lower the management costs of the general contracting company and the supervisory company and decrease the probability of corruption. In summary, the research findings provide valuable recommendations for combating corruption in international engineering projects and promoting the sustainable development of multinational business cooperation.
7. Limitation and Future Work
The limitations of this study and future work are as follows. (1) Research based on actual case data: This study constructs a theoretical model and conducts theoretical research on the impact of international reputation on corruption in multinational companies by using data from actual cases. In future studies, analysis and research can be conducted by incorporating data from actual cases. (2) Quantification method for reputation parameters: This study provides a method for quantifying reputation parameters as a reference for future researchers. Reputation evaluation indicators can be obtained from neutral organizations such as Transparency International and all data can be normalized within the range of 0–1 by dividing the maximum value in the dataset. (3) Different reputations for companies in different roles: Companies have different capabilities in various business areas, which means that a single fixed reputation value cannot represent the company’s reputation in all roles. Reputable companies may perform poorly in roles where they are not proficient. Therefore, it is worth considering studying a company’s performance in different projects.
