(Shujuan Yu, Yuan Wang and Huijun Wu., 2017).
which demonstrates the effective gain of schools,
government, and families in educational tourism.
Government participation or policy formulation plays
an important role, and tourism institutions will also
affect educational tourism (Lei Rong, 2021).
Moreover, the rapid development of the social
economy has shaken the cooperative relationship, put
forward new requirements for the government. The
government's support for families will change
enthusiasm of stakeholders. Therefore, the benefit
relations need to be reconsidered.
To sum up, the different demands of stakeholders
inevitably lead to contradictions, that is the game
between stakeholders under the background of reform
in education. Scholars mainly focus on students and
families. They are mostly empirical research and
qualitative analysis. The traditional research methods
fail to reflect the game relationship and conduct
analysis. Therefore, this paper studies the
stakeholders through the evolutionary game method,
which is not only conducive to expanding the
research ideas and enriching the application fields of
the evolutionary game but also conducive to
clarifying the contradictions between stakeholders
and the mutually compromised interest relations and
strategies, providing effective gains for the
implementation of educational reform and the
development of educational tourism.

Assumption 1 Educational tourism stakeholders
in this paper refer to the government, schools, and
families. Three stakeholders are limited rationality,
limited access to information, and commitment to
maximizing their interests.
Assumption 2 The income of educational
tourism of schools comes from family, so the cost of
family educational tourism should be directly
proportional to the total income of educational
tourism, but less than the total income. Therefore, the
family cost coefficient k
2
is introduced.
Assumption 3 Schools are the main position for
the development of educational tourism. Particularly,
when schools cooperate with institutions, educational
tourism is mostly outsourced to institutions, which
makes students have a poor sense of experience and
could not systematically acquire knowledge.
Therefore, this paper introduces the knowledge
acquisition coefficient k
3
.
Assumption 4 There are two strategic choices for
government subjects: Supervision and Non-
Supervision. The policy set is S
1
= (X
1
, X
2
). In
particular, when the government carries out
supervision, it rewards schools that incorporate
educational tourism into the education program and
build a complete system. In addition, the government
punishes schools that fail to implement the policy,
and grant subsidies to family participating in
activities. When the government is non-supervision,
schools and families will not be rewarded or punished
for any strategy. But the government can gain a good
reputation through regulation.
Assumption 5 There are two strategic choices for
school subjects: Non-Cooperation and Cooperation.
The policy set is S
2
= (Y
1
, Y
2
). The difference lies in
whether to choose to cooperate with institutions and
whether to build an educational tourism system
independently. When a school chooses to cooperate
with the institutions, the income should be shared
with the institution. The cost of cooperation should be
borne by the institution. When the school does not
cooperate with institutions, the school needs to build
an educational tourism system, and schools bear all
costs without sharing the profits.
Assumption 6 There are two strategic choices for
family subjects: Participation and Non-Participation.
The policy set is S
4
= (W
1
, W
2
). When the family
chooses to participate, the cooperation between
schools and institutions will reduce the acquisition of
family knowledge. Besides, the cost of family
participation in educational tourism is directly
proportional to the income of schools. The main
income of family participation in educational tourism
is reflected by the acquired knowledge. When the
family chooses not to participate, no matter what
strategies the schools and institutions adopt, it will not
have an impact on the family, and the knowledge
acquired through educational tourism is 0.
For the three-party game subjects, the strategy
choice of any two parties will affect the income of the
third party. Hence, in the case of incomplete
