Abstract:Grass-roots governance is the cornerstone of national governance. How to realize the modernization of grass-roots governance and improve the level of grassroots governance has been the core concern in the modernization of national governance system and governance capacity. Since the fourth Industrial Revolution,the iterative upgrading of digital technology has provided new development opportunities for the reform of urban grassroots governance. The grass-roots governments of various cities actively carry out innovative exploration of “technology + governance”,forming typical governance practices such as“whistle-blowing report,”“one-network management,”“four platforms of grassroots governance”and “Smart Chengdu”and so on,which effectively demonstrates the empowering potential of digital technology. But at the same time,there are also “pseudo-innovation” caused by“formalism” and “digital show-off”,resulting in the paradox of “negative”governance of technology. Therefore,the effectiveness of digital technology does not necessarily translate directly into the effectiveness of urban grassroots governance. So how can digital technologies effectively empower grassroots urban governance? This problem has aroused the interest from both practical and theoretical circles. As far as the existing studies are concerned,few of them involve the internal mechanism of digital technology driving grassroots bureaucracy and bureaucratic behavior changes to optimize urban grassroots governance,and no systematic theoretical framework has been designed. Based on this,this paper introduces the perspective of technology embedment into the field of grassroots governance,constructs the“structure rebuilding-relationship reshaping”analytical framework,and analyzes the internal mechanism of urban grassroots governance empowered by digital technology in combination with the governance practice of“one-network management”in Z-Street Town of S City. The findings are as follows:digital technology can reshape the power operation mechanism and soften the boundary of segmentation through structural rebuilding,thus alleviating the structural dilemma of urban grassroots governance. By reshaping the boundaries of linking government and community and connecting departments through relationships,digital technology promotes the formation of grassroots collaborative symbiosis network. In addition,based on the research data of “one-network management” empowering grassroots governance in S City,it is found that digital technology still exists in the process of empowering grassroots governance of cities,such as digital “suspension” and the insufficient effectiveness of “government-citizen interaction”. The reason behind the digital “suspension” may be that“bureaucratic governance”inhibits the vitality and autonomy of “simple governance”, and in the future,the relationship between the pressure system,bureaucratic system and grassroots autonomy can be balanced by giving play to grassroots party organizations and optimizing assessment indicators,so as to slow down the digital“suspension”. The cause underlying the insufficient effectiveness of“public-private interaction” may be that the logic of “upward responsibility” leads to the poor use of digital products,which reduces the enthusiasm of public participation. In addition,many matters that are suitable for offline disposal are required to be handled online ,causing an overload problem in grassroots governance,and greatly reducing the speed of government?s responsiveness. In the future,we should adhere to the people-centered approach to improve digital participation channels and scenarios,and mitigate the digital divide. At the same time,it is necessary to set reasonable boundaries between online and offline disposal of matters,reduce the burden of grassroots governance,and improve the agility of grassroots government response and the effectiveness of problem solving.
