Abstract: With the rise of the digital economy, novel employment forms that rely on Internet platforms have thrived, engendering a decentralized “platform-indiivdual” employment model. This new employment model has resulted in the atomization among workers employed in the new business forms giving rise to significant organizational challenges. Based on a three-dimensional analysis framework encompassing the structural, cognitive, and relational dimensions of social capital, this research delves into the processes and mechanisms underpinning the reorganization of workers in new business forms through social work interventions. Research has revealed that structural capital establishes organizational carriers for the reorganization of workers in new business forms, while cognitive capital imparts meaning. Relational capital ameliorates trust deficits inherent in atomized workers. The complementary dual-track functions of social work, namely, institutional substitution and catalytic medium, serve as crucial mechanisms for the construction of social capital among workers in new business forms.

Key words: social capital, institutional substitution, catalytic medium, new business form groups
