Moreover, the academic standards of these studies have been improved, and its research contents are diversified greatly. Hence, studies of trade unions in the future should combine structure analysis with mechanism analysis for better and more in-depth results. In addition, specific attention should also be paid to the historical study of trade unions in China across times.
