Abstract: Reinforcing the workhorse spirit is not only of great necessity for the overall strict construction of grass-roots party organizations at colleges and universities， but also is the realistic requirement for the party to construct grass-roots party organizations. Moreover， it serves as an important path whereby the grass-roots party organizations at colleges and universities could make an all-out effort to enforce strict party discipline. For the grass-roots party organizations at colleges and universities to strengthen the workhorse spirit in the current situation， they are faced with many challenges of both subjective and objective aspects， such as the complex environment of multiple variables， deviation of understanding and misinterpretation， and the work gap of the party at the basic level. In implementing the spirit of comprehensive and strict party construction and carrying out the spirit of the national conference on ideological and political work at colleges and universities， the sense of responsibility and the workhorse spirit should be strengthened， the workhorse spirit education should be highlighted in the ideological construction， the working standards in the organization construction should be enhanced， the feature of hard work should be formed in style construction， and action orientation should be embodied in system construction so as to actively respond to challenges and tests， and effectively build the grass-roots party organizations at colleges and universities into a strong battle fort and political core.
