In state-owned enterprises，enterprises are an important support for employees and grassroots party organizations. The party building of enterprises has a very close relationship with the cultural construction of enterprises. The party building of enterprises has laid a solid theoretical foundation and correct construction direction for the construction of corporate culture. In order to study the promotion of grassroots party building to corporate culture，this report selects a petroleum industry state-owned enterprise in Guangzhou to conduct a questionnaire survey. The results show that employees have strong recognition of party building leading and promoting corporate culture construction，and believe that party building can promote production and management activities. However，party members and staff members did not prefer party organizations when they encountered difficulties in production and life. It is suggested that the next phase will focus on how to further improve the scientific and effective construction of grassroots party organizations.
