In 2022, Chengdu's GDP will reach 208 trillion yuan, becoming the third sub-provincial city in the country with an economic aggregate exceeding 2 trillion yuan and the first permanent population exceeding 20 million, officially entering the ranks of megacities. In 2023, Chengdu will achieve another impressive economic growth rate of 6%.
The rule of the big city is complicated.
In this megacity, there is a set of figures updated in seconds: the city on the ground has a permanent population of 21.38 million, a floating population of more than 2 million, about 23,254 high-rise buildings and 2,739 super high-rise buildings over 100 meters, and 662 motor vehicles560,000 units, ranking first in the country; In the underground city, there are 14 lines and a total mileage of 601 kilometers of rail transit, which transports more than 615 per working day10,000 passengers, and 9930,000 kilometers of underground pipelines and 121The 8-kilometer comprehensive pipe corridor always guarantees the supply of various basic services in the city; The city on the clouds, there are more than 780,000 5G base stations and 1,791 ** information systems are running rapidly, more than 100,000 cloud enterprises are on the cloud, and 169.3 billion pieces of data are aggregated, shared and interacted in real time.
Ultra-large-scale, ultra-high-density, ultra-high speed, and ultra-high complexity bring common challenges to the governance of China's megacities. As a national central city and a polar core city in the Chengdu-Chongqing region, how can Chengdu answer the "people's question" of efficient governance and high-quality development of a megacity?
One of the key grasps chosen by Chengdu is to make a forward-looking layout and deepen the cultivation of "smart Chengdu".
Wang" shaped city management structure.
When night fell, Deng Jiangrong, who lives in Jingcheng Garden Community, Wenjia Street, Qingyang District, Chengdu, changed into sportswear and prepared to go for a run in the park downstairs.
Today's Jingcheng Garden Community has a pleasant environment, surrounded by greenways and fitness facilities. A few months ago, it was a different scene - there was a landscape ditch next to the community, which was unmaintained, and it was easy to accumulate water when it rained, and over time it formed a black and smelly water body.
At the end of 2023, Deng Jiangrong reflected this problem to Li Linli, a member of the community grid. Li Linli immediately came to the scene to check after receiving the report, and reflected the situation upwards through the "Qingyi Office" mobile platform. "I didn't expect it to be reported to the Qingyang District Smart Rongcheng Operation Center (hereinafter referred to as the "Urban Transportation Center") in less than 10 minutes, and handed over to the District Comprehensive Law Enforcement Bureau, and the problem was quickly resolved," Deng Jiangrong told this reporter.
From the "Qingyi Office" to the urban transportation center, Qingyang District has strung thousands of threads with "one needle", and innovated an urban management method that promotes offline implementation and improvement with online standardized processes.
Zhang Xiang, deputy director of the Qingyang District Urban Transportation Center, said that the center has gathered 9More than 900 million pieces of data, more than 600 indicators of urban signs, more than 90,000 various perception sources, and more than 190 types of map elements can be superimposed to check the "vital signs" of the city around the clock.
Feng Xiufu, director of the Chengdu Urban Operation and Government Service Management Office, introduced that after two years of actual operation, Chengdu has initially built a "king" city management structure of "first-class platform and five-level application".
In terms of offline, as an operational entity to promote the construction of "one network and unified management", the Municipal Urban Transportation Center, 40 urban transportation sub-centers of municipal departments, 23 districts (cities) and counties, and 261 town and street urban transportation centers are fully covered and operated.
In terms of online, combined with the functional positioning of the urban transportation center, the corresponding construction of the "one network unified management" technical system platform - this "king" character is vertically connected to the urban transportation system through data interaction, event disposal, and instruction circulation. The urban transportation platform then extends down to the village (community) and grid, forming a five-level application.
* The platform and five-level application, vertical to the end, horizontal to the edge, build a closed loop of "perception and discovery, decision-making and command, response and disposal, and terminal feedback", and promote the profound transformation of urban operation from post-event statistics to ex-ante statistics, from passive disposal to active discovery, and from Kowloon water control to overall "intelligent governance".
24 hours a day, 365 days a year.
The IoT sensing system based on new information technologies such as the Internet of Things, AI algorithms, and big data analysis is an important foundation for the construction of smart cities.
It is a key part of the construction of a new smart city to set up sensing terminals in the city, collect and monitor diversified perception data in real time, intelligently mine and analyze data information, and realize the real-time perception of the main vital signs of the city.
In July 2022, Chengdu officially established the "Smart Chengdu Urban IoT Perception Center" (hereinafter referred to as the "Perception Center").
Zhang Rong, head of the R&D technology center of Chengdu Chengtou Smart City Company, told this reporter that the perception center has connected to more than 23.8 million terminals, gathered 12 billion IoT data, shared 2.54 million sensing terminals externally, and pushed 4 billion sensing data. From installing intelligent sensors on bridges to grasp the vibration amplitude of the bridge deck and bridge body at the first time to judge whether the bridge needs maintenance, to installing door magnets in the homes of the elderly living alone, and combining them with water, electricity, and gas meter data to determine whether the elderly need care in a timely manner.
Another important source of urban perception in Chengdu's layout is located underground.
On the one hand, the underground comprehensive pipe gallery can "accommodate" power cables, communication optical cables, water pipelines and other pipelines, so that the city can stay away from the "spider webs in the air", and on the other hand, it can also arrange various sensing equipment to become the underground perception source of the smart city.
It is about 3 kilometers long and 5 kilometers wideThe underground comprehensive pipe gallery in the Yazhou Road area of Tianfu New District, which is 4 meters high and 3 5 meters high, can accommodate a car to pass through, and is one of the largest pipe corridors with a single cabin section in the country.
Zhang Jun, a staff member of the Park City Construction Bureau of Tianfu New District, Sichuan, introduced that the pipe gallery is divided into comprehensive 1 cabin and comprehensive 2 cabins. Cables, communications, water distribution pipes, reserved reclaimed water and other pipelines are laid in the first cabin, and water transmission pipes, reclaimed water pipes and reserved energy pipes are laid in the second cabin.
Through sensors all over the pipe gallery, the platform detects various data such as temperature, humidity, and oxygen content in real time 24 hours a day. If there is an abnormality, the early warning information will be pushed to the sub-control center platform as soon as possible, and the fan, pump and other equipment will be automatically turned on for disposal.
The reporter also saw at the scene that in the underground comprehensive pipe gallery, the inspection robot was also on duty. The inspection robot is shaped like a car, integrating "black technology" such as inertial navigation, visual navigation, image recognition and automatic charging, and can automatically collect, analyze and alarm the diseases of the pipe gallery.
Luo Jian, director of Chengdu Big Data Center, said that in the next step, Chengdu plans to give priority to accelerating the deployment of encrypted sensing sources in street lamp poles, underground comprehensive pipe corridors, gas pipeline networks, etc., and strive to access 50 million sensing terminals during the "14th Five-Year Plan" period, so as to create a "full-time, full-range, and full-coverage" urban perception neural network, and conduct 24-hour, 365-day-a-day intelligent physical examination of urban vital signs.
One-click response.
Smart Chengdu is also an important starting point for promoting the re-optimization of Chengdu's business environment.
The "Opinions of the Chengdu Municipal Committee of the Communist Party of China on Optimizing the Business Environment by Relying on the Construction of Smart Chengdu" adopted on December 27, 2023 pointed out that it is necessary to "focus on the development needs of the whole life cycle of enterprises, coordinate and promote the 'one-stop service' of government services, the 'one-stop response' of policy elements, the 'one-click response' of enterprise demands, and the 'one-network unified management' of economic operation, so as to accelerate the creation of a market-oriented, law-based, and international first-class business environment".
The all-in-one network is accelerating its popularity in Chengdu.
The application "Tianfu Rong Easy Office" can provide 930 items for the daily life of citizens, and can also provide convenient handling of 1,892 government service items for the whole life cycle of enterprise production and operation.
Chengdu, which is speeding up the construction of the Chengdu-Chongqing Twin-City Economic Circle and the Chengdu-De-Meizi (Chengdu, Deyang, Meishan, Ziyang) metropolitan area, is also promoting the integration of smart government services with the above-mentioned cities. At present, 209 Chengdu-Chongqing communication matters can be handled online, 311 Sichuan-Chongqing communication matters and 241 Chengdu-Demei information communication matters can be handled efficiently.
For example, in the past, Chongqing residents had to travel back and forth between the two places many times to settle down in Chengdu. Today, the migration of household registration in Sichuan and Chongqing has been completed in one stop, and the processing time has been reduced from 20 days to 24 hours.
12345 Citizen Service** is the general platform of Chengdu's "one-click response".
In the ** answering center of more than 2,000 square meters, nearly 200 people are on duty every day, 7 24 hours a day, with an average of more than 20,000 ** access per day, and more than 20 million citizens maintain calls all year round.
The highlight of 12345 citizen service** is that every ** received ** "must respond" - the operator can not answer the question on the spot, will be recorded in detail and form a work order, after the review and confirmation of the content, the work order will be sent to the corresponding department for processing, and need to be completed within the specified time limit. For appeals involving potential urban public safety hazards, there is also a mechanism for escalating the disposal, which can be submitted to a special class for speeding up the disposal of the appeal and sending it to a higher level for direct handling.
In 2023, the Chengdu Municipal Party Committee and Municipal Party Committee launched the "12345 Qinqing**" at the "First Meeting of the New Year", which innovatively integrates the "12345 Helping Enterprises**" that can be dialed 7 24 hours a day, so that enterprises can run away less, the applications "Tianfu Rong Easy to Do" and "Tianfu Rong Easy to Enjoy", as well as the offline exchange meeting with enterprises "Rong Yi See" Four major service methods, four in one, convenient for enterprises to benefit enterprises, and enterprises respond enthusiastically.
In one year, "12345 Qinqing**" has received a total of 11 corporate consultations, suggestions, and appealsMore than 400,000 pieces, an increase of about 7 percent year-on-year5 times, the appeal resolution rate and satisfaction rate are more than 95%.
At the same time, in 2023, there will be 60 new business entities in Chengdu180,000 households, a year-on-year increase of 375%, the total number of business entities in the city reached 389120,000 households, ranking second among sub-provincial cities in the country, and the smart Chengdu city has achieved remarkable results in empowering the business environment.
On February 18, 2024, the theme of the "First Meeting of the New Year" of the Chengdu Municipal Party Committee and Municipal Committee once again focused on the "12345 Qinqing**" On the same day, at the Chengdu Municipal Party Committee and Municipal "12345 Qinqing**" to optimize the first-class business environment, the six innovative application scenarios of "12345 Qinqing**" were officially released.
Among them, "Rongyi Loan" brings together 8 inclusive financial products through a unified entrance to help solve the problems of "difficult financing, expensive financing and slow financing" for small and medium-sized enterprises. "Rong Yi Use" is led by Chengdu Data Group to build Chengdu Data Park, so that data can be supplied, flowed and used well. "Chengdu Tax and Happy Enterprise" makes enterprise tax payment smarter, more convenient and more worry-free. "Rongyi Sue" creates a litigation intelligence platform with a full cause of action, full chain, full intelligence, all-weather, and full interaction, so that enterprises no longer "run to the court and wait for notices". "Rong Yixiang" brings together 2,091 national, provincial, municipal, district (city) and county policy documents in the effective period, with a total of 1,737 items that can be declared and 96 items that can be enjoyed without application, and actively pushed to enterprises, providing enterprises with one-stop policy services that can be found, understood and done.
In addition, Chengdu will fully implement credit reports, and business entities only need to issue a special credit report, which can replace a stack of certificates of no violations of laws and regulations.
Yang Guangyi, director of the Network Management Division of the Chengdu Urban Operation and Government Service Management Office, told this reporter that the purpose of the "Rongyi +" series of application scenarios is to build ladders, clear runways, and clear roadblocks for enterprises, which fully demonstrates Chengdu's greatest sincerity in empowering with wisdom and transmitting the city's temperature to enterprises.
Online and offline integration.
In the Spring Festival of the Year of the Dragon, Chengdu's popularity was "hot and hot". According to Tencent's location big data, Chengdu is the most popular city in China during the Spring Festival holiday in the Year of the Dragon. Meituan's 2024 Spring Festival "Eat, Drink and Play" consumption data shows that Chengdu ranks second in the country in terms of dine-in orders for non-local tourists, with a year-on-year increase of more than 210%.
Xiao He, a tourist from Luoyang who came to Chengdu for the first time, told this reporter that although there were many people, she felt the comfort of the city. She was particularly impressed by the bike-sharing in Chengdu, where "there are almost no common cases where vehicles occupy the road at will and are damaged and cannot be used".
Huang Haiqiang, a staff member of the City Appearance and Advertising Signboard Management Office of the Chengdu City Management Committee, told this reporter that the reason why tourists experience comfort is because Chengdu has established the country's first online and offline linkage, enterprise and ** collaborative "shared bicycle intelligent supervision system".
Specifically, Chengdu has established a dynamic management system of "red, yellow, blue and green" through big data monitoring and short-range Internet of Things - red represents oversaturation of vehicles, yellow represents imminent overexertion, green is normal value, and blue represents insufficient vehicles.
If the system status is red and lasts for up to 10 minutes, the system will automatically send a work order to the handheld app of the car company to which the bike-sharing belongs to remind them to transfer the excess bikes to the nearest blue spot area. The background of the system will also track the work order disposal process in real time, and the operation and maintenance personnel will take photos and upload them to the system after completing the dispatch, and the work order will be closed, forming a closed loop.
At the same time, the street urban management team members synchronously command and dispatch through the handheld terminal, and directly connect with the operation and maintenance personnel of the car company and command remotely, so as to realize the full intelligent supervision of "both vehicle management and people".
After the launch of this system, the idle rate of shared bicycles in the central urban area of Chengdu has decreased by 30% and the utilization rate has increased by 50%.
Chen Hongyu, head of the "Smart Chengdu Construction" research group of the Political Research Office of the Chengdu Municipal Party Committee, told this reporter that under the current trend of interconnection of all things and ubiquitous data, "digital intelligence benefiting the people" has become an inevitable move to create a high-quality life, "wisdom and efficiency" has become a powerful starting point for the implementation of high-efficiency governance, and "digital and real integration" has become an important way to promote high-quality development. In the future, Chengdu will promote the high-quality development of the digital economy, strengthen the "two-wheel drive" of industrial digitalization and digital industrialization, and accelerate the shaping of the core competitiveness of the city's industries.
