Optimizing the business environment is a critical strategy for fostering and stimulating market entity vitality and enhancing the endogenous driving force of economic development. Municipal public utilities constitute a vital component of the business environment and have been a focal point of domestic reform efforts in recent years. In 2023，the World Bank officially launched the new B-READY business environment evaluation framework to align with evolving global economic and investment trends. Building on an initial analysis of the B-READY framework’s provisions concerning municipal public utilities，this paper conducts a policy-text-based comparative examination of the latest reform dynamics in these five cities’ business environment improvement initiatives. The research shows that all five cities have enhanced the efficiency of utility connection approvals and ensured service quality，while simultaneously strengthening transparency，establishing robust complaint and regulatory mechanisms，and improving the stability，reliability，and security of service delivery. All five cities are focusing on promoting integrated application，parallel approval，and joint site inspection for water，electricity，gas，and network services，as well as developing cross-project infrastructure networks. Overall，these reform trajectories exhibit strong alignment with B-READY assessment indicators，while also reflecting distinct local pathways and characteristics.
