基于湖南省汨罗市桃林寺镇12位返乡创业相关者的深度访谈，运用扎根理论研究方法，探索农民工从返乡到创业的动态机制。研究结果发现：家庭使命召唤和家乡使命召唤共同推动农民工返乡；农民工返乡后创业的机制，体现为创业机会、推力与阻力交互作用实现个人与环境的动态契合，创业机会来源于个人发掘和政府引导，推力来自家庭支持和创业经验，阻力来自于行业转变和身份转变；从返乡到创业的过程具有使命驱动特征，表现为从使命源头到使命感知、再到使命践行。

Through in-depth interviews with 12 stakeholders involved in return migration and entrepreneurship in Taolinsi Town, Miluo City, Hunan Province, this study employs a grounded theory methodology to explore the dynamic mechanism of migrant workers transitioning from return migration to entrepreneurship. The findings reveal that: both family calling and hometown calling jointly drive migrant workers' return migration. The entrepreneurial mechanism post-return is characterized by a dynamic Person-Environment Fit achieved through the interplay of entrepreneurial opportunities, discovered both individually and through government guidance, along with driving forces such as family support and prior experience, and resisting forces stemming from industry shifts and identity transformation. The entire transition from return to entrepreneurship is calling-driven, manifesting as a progression from the source of calling to perceiving a calling and subsequently living a calling.
