Abstract: In the context of the digital economy era, new employment groups are increasingly engaged in the construction of public life through new forms of labor, yet simultaneously face structural alienation from broader social participation. In response to this governance challenge, Community J has adopted a party-building approach to facilitate the involvement of new employment groups in grassroots governance. This process achieves social integration of delivery riders within the jurisdiction through a tripartite integration strategy: first, creating interactive spaces through spatial integration to establish a foundation of trust; second, benefiting service recipients through service integration to bring the party closer to the new groups; and third, incorporating volunteer actions through volunteer integration to promote community cohesion. In the process of party-led new employment groups participating in grassroots governance, grassroots party organizations use governance relationships as a link to achieve effective integration of stakeholders and shape social solidarity at different levels: by closely connecting the party with new employment groups through service coverage and governance absorption, by promoting internal identity among new employment groups through external affair governance, and by strengthening neighborhood interactions to achieve overall community cohesion.
