Expanding domestic demand and cultivating a complete domestic demand system urgently need to unleash the consumption power of rural residents. Has the digitalization of inclusive finance effectively unleashed the consumption power of rural residents What role does the optimization of the consumer environment play in this process Based on the systematic comb of the principles underlying the relationship between the digitalization of inclusive finance the optimization of consumption environment and the release of rural residents' consumption power this study empirically tests the release effect conduction mechanism and threshold effect of the digitalization of inclusive finance on the consumption power of rural residents from the perspective of the optimization of consumption environment by using the provincial panel data from 2011 to 2021 in China. The results show that the digitalization of inclusive finance has a significant positive impact on the consumption of rural residents indicating that it promotes the consumption of rural residents and is conducive to releasing the consumption power of rural residents. The digitalization of inclusive finance can release the consumption power of rural residents by promoting the optimization of the consumption environment that is the optimization of the consumption environment is the conduction mechanism for the digitalization of inclusive finance to release the consumption power of rural residents. The release effect of the digitalization of inclusive finance on the consumption power of rural residents has a threshold effect based on the consumption environment that is the release effect varies significantly across different threshold ranges of the consumption environment. With the further optimization of the consumption environment the role of digital inclusive finance in unleashing rural residents' consumption power will continue to strengthen. The digitalization of inclusive finance has promoted the both subsistence consumption and the development and enjoyment consumption among rural residents facilitating the comprehensive release of the consumption power of rural residents. However compared with subsistence consumption the digitalization of inclusive finance more effectively unleashes the power of the development and enjoyment consumption of rural residents which is conducive to promoting the upgrading of the consumption structure of rural residents. The policy implications of the research conclusions include firstly deepen the digitization of inclusive finance promote its deep integration with rural industries development strengthen the innovation of digital financial products such as online consumer loans and Internet finance and coordinate the development of digital inclusive finance across regions to help release rural residents' consumption power. Secondly fully promote the optimization of the consumption environment focus on the governance of the rural circulation field build a smooth and efficient rural circulation infrastructure system establish a systematic platform for protecting rural consumers' rights and create a safe and favorable rural consumption environment to fully stimulate the consumption potential of rural residents. Thirdly formulate differentiated strategies to increase residents' income scientifically plan the coordinated development of small cities and towns comprehensively address the "one old and one young" population structure issue and systematically leverage synergy effect of factors such as rural residents' income urbanization development population age structure on consumer spending.
