The results show that, from the perspective of content, gig workers have gained greater choice space, more employment opportunities and increased income; the current labor regulations and social security policies are lagging behind and the platform management system is unreasonable, so the conditions of gain is not ideal; from the perspective of approach, gig workers have a large workload and limited career upward channels; from the perspective of experience, not many people have a positive attitude towards work, and the main reason for negative emotions is not being respected by the society; in terms of sharing of gain, nearly 70% of gig workers showed willingness to participate in society and sense of social responsibility.
