Abstract: As an important force in China's socio-economic transformation, the new generation of migrant workers have great potential and prospects. Advocating and supporting their independent entrepreneurship will not only help solve their own employment problems, but also indirectly create employment opportunities for others, and further promote the high-quality development of China's economy and the stable progress of society. However, the new generation of migrant workers is often faced with a huge resource constraint, and it is often difficult for them to obtain sufficient support in terms of capital, technology, market, and other key resources in the start-up stage. The lack of resources makes the entrepreneurial path of the new generation of migrant workers fraught with uncertainty and increases the risk of failure. Based on the theory of entrepreneurial bricolage, it is known that entrepreneurial bricolage is an important means for entrepreneurs to get rid of resource constraints and develop new opportunities. Therefore, in order to promote the new generation of migrant workers to get rid of resource dilemmas and achieve successful entrepreneurship, it is necessary to identify the various factors that influence and stimulate their entrepreneurial bricolage behaviour. This study investigates the effects of opportunity innovation and resource constraints at the level of entrepreneurial context, as well as risk preference and opportunity cognitive beliefs at the level of individual characteristics, on the entrepreneurial scrambling behaviours of new-generation migrant workers through a survey experiment. The study selected and collected survey data from 295 new-generation migrant workers, conducted reliability and validity tests using data analysis software, and tested the research hypotheses using hierarchical linear regression analysis. The results showed that (1) opportunity innovation and the degree of resource constraints in the entrepreneurial context have a significant effect on the entrepreneurial bricolage behaviour of new generation migrant workers; (2) opportunity cognitive beliefs in individual characteristics significantly affect the entrepreneurial bricolage behaviour of new generation migrant workers, while risk preference has no significant effect on the entrepreneurial patchwork behaviour of new generation migrant workers; (3) both high opportunity innovation and more opportunity cognitive beliefs promote the entrepreneurial bricolage behaviour of the entrepreneurial patchwork behaviour of the new generation of migrant workers, while strong resource constraints inhibit the entrepreneurial bricolage behaviour of the new generation of migrant workers. The study enriches and deepens the research on the antecedents of entrepreneurial scrambling behaviour, and provides references and suggestions for the entrepreneurial scrambling practices of new generation migrant workers. For the government, (1)Optimize the innovation environment and create a social atmosphere that encourages innovation. (2) Optimize the resource environment and alleviate the resource constraints on entrepreneurial bricolage behaviour. (3) Optimize the entrepreneurial environment and stimulate the entrepreneurial enthusiasm and creativity of the new generation of migrant workers. For the new generation of migrant workers, (1) Improve innovative thinking and bring into play the positive impact of opportunity innovation. (2) Promote the use of resources and constantly explore new resource utilization models. (3) Enhance the awareness of opportunities and learn to identify and make use of them.
