Since 2005, a revolutionary change has been unfolding in the administration of Chinese cities, realized through the combination of modern information technology (bases on computer communications and simulation) with fine-grained social and geographical organization based on small urban cells. This combination is described as (Digital City) Grid Management.

 

The initial laboratory for this new approach was the Dongcheng District of Beijing, Where a discussion group was formed in April, 2004, to computerize the existing model of urban management while deepening community involvement. the district's 25.38 square kilometers were divided into a mesh of 1,652 irregular cells, woven together by electronic 'grid links'. Each of these cells was treated as a specific management unit within an overall four-level hierarchical structure. Not only was each facility and installation. from street signs and parking meters to individual trees, garbage bins and fire hydrant, had its own identity code and generic icon to file it within the urban management information system database and plot it on dynamic displays.

 

The real key to the system however, was the street-level army of monitors who raved their allotted territories, using standardized PDAs to snap photos of anything that had triggered complaints or seemed to them amiss, then electronically sending the images up to the administration. When problems had been addressed, a second photo of the sense was taken to confirm that a successful outcome had been achieved.

 

The new system was tested during the 2005 Spring Festival, when an unprecedented ban on fireworks in Beijing was being enforced. The combination of responsible local involvement with peripatetic monitors and integrated digital technology (including wireless telephony. Internet and global positioning) proved highly effective and the model received the go-ahead for propagation to other urban areas.

 

With accelerating urbanization in China expected to encompass 40% of the population by 2010 and exceed 50% by 2020, the need for a long-term management solution for the inevitable social and technical pressures was widely perceived among Chinese municipal authorities. the Grid approach, modeling citied as sets of information flows amenable to continual real-time fine-grained monitoring, was eagerly seized upon, drawing support at the national level from the Ministry of Science and Technology. In July, 2005, Shanghai's Luwan and Changning Districts were among those selected among 10 cities nationwide for second-phase demonstration projects essential to further standardization and development of the system in all its legal, administrative and technical aspects.

 

By adapting philosophically, structurally and technologically to feedback-driven administration based on Grid Management the Shanghai authorities pioneering the system have been able to reap significant cost reduction along with improvements in the supervision and appraisal of their own activities and personnel. They have also been able to refine the evaluation and targeting of public service and increase their capacity to dynamically manage rapidly complicating issues of multicultural and regional diversity, traffic congestion, sanitation, pollution and network stress.

 

Shanghai's Luwan District, whose 7.53 square kilometer area were divided into 439 mesh cells, has been specially commend as a "digital urban management pilot city" based it's 99.55% resolution rate for reported problems. these have included offense vagrancy and begging, missing sewage covers, impediments to blind pedestrians, damaged road signs, abandoned vehicles, exposed garbage, illegal street and vending fly-posting, graffiti, burst water mains and excessive vehicle emissions, among many others.
