Group conflict is one of the main human conflicts in the history of human development and results in various forms such as competition, fight, riot, or war in extreme cases and compromise, negotiation, or cooperation in other cases. The inner essence of the group conflict is competitors vying for resource control. If the conflict ends up at a situation where one party overwhelms the other, it will actually bring destructive results to both sides. Is there a solution to avoid fierce conflicts and to achieve a win-win situation? Is there a unified model by which different forms of conflicts can be interpreted and studied? The purpose of this paper was to address these problems and attempt to establish such a unified model and to use it to analyze the dynamic relationship between the employees and their employers in the viewpoint of group conflict and symbiosis. By changing coefficients of the unified model, the two sides, employers and employees, could be in different situations such as employer win, employee win, lose-lose, and win-win. Keeping other coefficients unchanged, we found and proved that there is a win-win strategy space of the payoff rate. Two parties chose strategy within the space can achieve optimal status in long run.
Force disputes and economic conflicts between neighboring countries, among different regions, ethnic groups, and social groups, and even world wars are all originated from “resource allocation,” in which political conflicts are also usually ended with. Resources here refer to natural resources, economic resources, social resources, environmental resources, and so on.
It was reported in 1993 for the first time that more than 8,700 social group events occurred in China in that year. By the end of October 31st, 2016, there have been 2 million social group events occurred within the past 24 years. Performing cluster analysis on the causes of group conflicts, we concluded four major categories: land acquisition and demolition, environmental pollution, labor disputes, and unfair law enforcement. Nearly 50% of group conflicts were caused by land acquisition and demolition, about 30% were caused by environmental pollution and labor disputes, and the other 20% were caused by law enforcement and other social contradictions.
As mentioned above, the proportion of land acquisition and demolition conflict, environmental pollution conflict, and labor conflict reached 80%. Through further quantitative analysis, it was found that the basic contradiction of social group events is “resource allocation.” All land acquisition and demolition conflicts are originated from land resources allocation; all environmental pollution conflicts are originated from resource allocation relevant to the environment; the occurrence of all labor conflicts also cannot be separated from employment resources allocation, human resources and remuneration allocation, and the price of human resources.
In the case of labor conflicts, employers cannot meet the expectations of workers for labor remuneration, which can easily lead to labor protests, petitions, strikes, and even social unrest. In reality, employers pay more attention to the level of labor remuneration from the whole profits and losses, while labors care more about the amount they think they deserve based on current social conditions. Resulting from different standpoints, different opinions, and two sides in a stalemate, conflicts occur from time to time and become one of the main problems in the whole society.
Labor conflicts or labor disputes refer to employers and employees negotiating on payment or related welfare from respective positions. Some conflicts were solved soon, while other conflicts not only lasted for a long time but led to the suffering of both employers and employees from large economic losses, causing huge social influence at the same time. Can we find a win-win solution between employees and employers to reduce or avoid fierce conflicts and ensure sustainable cooperation? Then, can we find a more general, sustainable, collaborative, and win-win situation which caters to all kinds of groups based on conflicts of “resource allocation”?
Much effort has been devoted to the study of labor disputes from many perspectives, but few scholars have made research on this issue from the perspective of mathematical modeling. Chan and Hui analyzed the labor strike in China and concluded there would be transition in the collective negotiation process of China from the aspects of political economics [
Many researches applied different approaches in studying group conflicts, such as diffusion models, game theory, and psychology. Well-known diffusion models have been adopted to study the competition relationship. Morris and Pratt addressed the special case that a dominant competitor at equilibrium is replaced after the introduction of a small population of an invading competitor with a competitive advantage and analyzed the behavior of the Lotka–Volterra competition (LVC) equations in such a case. He also compared the dynamics of LVC competitive substitution to that of several well-known substitution models [
Pietraszewski addressed the conflict problem from a psychological point of view [
Some researchers also explored the conflict issue using game-theoretic models. Smith and Price looked into the logic of animal conflicts [
However, research that explains the symbiotic issue is sparse [
This research studies if there exists a unified dynamic mechanism between social group conflicts and symbiosis from the aspect of ecological dynamics. We mainly focus on labor conflicts. During the process of real labor conflicts, for example, labor conflicts occurred as the result of remuneration all over China in recent years, employees and employers usually negotiated on requirements such as employers modifying payment standard to pay lower wages, employees asking for increasing remuneration, subsidies, and wages, and so on. Employers hoped to reduce remuneration and employees asked for increasing payment, none of them compromised. Then, the climax of negotiations might result in the form of labor strikes, lasting for several hours (e.g., workers from a state-owned enterprise paraded in December 2011 in Chengdu, Sichuan) or more than ten days (e.g., Honda Strike in June 2010 in Foshan, Guangzhou). These conflicts usually negatively affected production operations, ending up as both sides reaching a compromise (e.g., in the Honda strike, the final solution was to raise 500 yuan in basic wage for each staff, compared to a raise of 800 yuan required previously by workers). The aim of this research is not to discuss the simple labor agreement relationship between employees and employers or a one-time labor conflict. Instead, we study if it is possible to build a long-term sustainable cooperation relationship, to make two sides obtain higher revenue and achieve win-win between employees and employers.
In most cases, cooperation between employees and employers is not a one-time, but a long-term and continuous relationship. Especially in industries demanding for skills and experience, the training cost will absolutely increase if relations of cooperation change very often. As for labors, life will be undoubtedly unstable if they change jobs frequently. Therefore, it is beneficial for both employees and employers to build a long-time and steady relationship.
What is a long-time and steady relationship? That is, through a reasonable “resource allocation” strategy, resources attained by both sides could always be in a stable situation above the initial value as negotiated.
Employees usually ask for remuneration increase because of various social factors, such as price rise, labor intensity increasing, working hours increasing, social psychological reasons, and so on. On the contrary, employers may execute layoff or reduce wages for the sake of price for raw materials going up or bad losses of enterprises. However, employees and employers usually disagree with each other, thus leading to labor conflicts. Dynamic evolution features between employees and employers are mainly represented as the following aspects: Employees and employers hope to achieve a win-win situation Win-win refers to making resources that two sides obtained be continually in a stable situation above the initial value as negotiated by the “resource allocation” strategy. In this research, we assume Uncertainty of evolution paths The result of long-time evolution of labor relations is not unique. Win-win is just one of the evolution paths, and it may also turn out to be single win or double lose. It is uncertain that in which path employees and employers will evolve along and which stable situation they will arrive at when adopting different strategies. Long-time evolution results between employees and employers depend on initial resources The final evolution results of labor conflicts are also closely related to initial conditions. Different initial conditions will lead to different results. Mutual interdependence and mutual restraint between employees and employers Similar to the population in ecological systems, there exists mutual interdependence and mutual restraint between employees and employers
The relationship between employees and employers is a special case of ecological problems and is analogous to the dynamics of sheep-grass or lynx-hare. However, this kind of sustainable dynamic evolution is different from the traditional predator-prey ecological problems. The evolution result is the stable solution that two sides continually obtain resources, but not the periodical oscillating solutions in the predator-prey model. This kind of sustainably developing problem is widespread in human society.
In the study of traditional populations and ecological dynamic problems, different dynamic models are used to describe different relationships between species.
The following three set of equations (
In reality, both sides of a social group conflict are in the same social condition, and the structure of the group itself and the structure of the relationship between groups are also fixed. Therefore, the conflicting social groups follow unified rules when making resource allocation. It is different from traditional populations and ecological dynamic problems, in which different dynamic models are applied to describe the relationship of cooperation, competition, and symbiosis between species. Then, we want to know if there exists a unified model structure which can evolve a competitive, cooperative, and symbiotic relationship only by different coefficients. In other words, the conflicting two sides can combine out relationships of competition, cooperation and symbiosis only by changing strategies (changing coefficients of the unified model structure). By extension, is it possible for the conflicting two sides to sustainably obtain resources through cooperation instead of fierce disputes?
Based on dynamics theory, the dynamic relationship between employees and employers can be illustrated in Figure
The dynamic relationship of employers and employees in a long-term cooperation (the right triangle “
As shown in Figure The employers make his profit from the primary business and the secondary business, respectively, with a growth rate of Employees get payoffs from employers, including but not limited to base salaries, overtime allowances, and bonuses, which are labor costs for employers. The parameter Besides payoffs from employers, employees also get other incomes such as subsidy and bank interest, which increase with a growth rate of Employees have to suffer the cost of living, including but not limited to commuting cost, skill learning cost, and living necessities cost, which increases with a growth rate of There will be a decline in growth in employers’ making profits owing to market saturation or raw materials shortage. Physical and mental fatigue can hinder employees from working long hours.
Thus, the dynamic model can be written as follows:

The values of parameters in the four cases are partially based on the real labor disputes, which had similar circumstances, but different endings in the dispute because of different strategies.
Given the initial value
The simulation result and the phase diagram in the employer win situation.
The numerical simulation shows that it favors employers in this situation, in which employers provide low payoffs to employees and obtain continuing growth in resources. On the contrary, employees do not harvest from their work due to low payoffs. The employer win situation is unsustainable. As time evolves, resources are overwhelmingly possessed by employers while employees own less and less. This is a situation called employer win.
Given the initial value
The simulation result and the phase diagram in the employee win situation.
The numerical simulation shows employees will tend to have the continuing increase of resources with high payoffs. On the contrast, employers will suffer a high operation cost of production activity and their resources no longer increase with time. In all, it is a case of employee win.

The relationship between employees and employers that needs long-term cooperation was mutually interdependent, dynamic, and continually evolving. The two sides should be more concerned about the long-term benefits rather than immediate ones. As long as employees and employers rationally and compromisingly negotiated within a win-win strategy space, it was possible to find a strategy for both employees and employers to continually obtain resources above the initial value, achieving stable and sustainable development.
That is to say, there actually existed a unified model structure which could depict relationships of cooperation, competition, and symbiosis only by different coefficients. Comparatively, different dynamic models are adopted in traditional populations and ecological dynamic problems to describe the relationship of cooperation, competition, and symbiosis between species. In our model, changing strategies of the conflicting two sides could lead to relationships of competition, cooperation, and symbiosis, that is, changing coefficients of our unified model structure. By extension, it was possible for the conflicting two sides to obtain resources sustainably through cooperation instead of fierce conflicts.
In conclusion, the conflicts between social groups were not irreconcilable, but on the contrary, there indeed existed a win-win strategy space rather than an ideal point in theory. Therefore, there was not only an ideal theory, but a practical and optional space corresponding to various strategies which can be realized.
