In 2020, "Chengde Meizi City Integration" has become a hot topic.

Especially after the second meeting of the Sichuan Provincial Leading Group for Promoting the Integration Development of Chengdu, Meishan and Ziyang was held on July 27, promoting the integration of Chengdu and the three cities of Deyang, Meishan and Ziyang has become a key move in building the Chengdu metropolitan area.

In 2019, the above-mentioned four cities achieved a regional GDP of 2.15 trillion yuan, accounting for 46.1% of Sichuan Province.

The Sichuan Provincial Development and Reform Commission stated that the Chengde Meizi area has superior natural conditions, profound cultural heritage, rich scientific and educational resources and a solid industrial foundation. It is the area in the central and western regions of my country that has the best conditions to take the lead in building a modern metropolitan area.

Chengdu City stated that promoting this urbanization development will help break the administrative divisions and traditional urban and rural structures, explore a four-level spatial system of "metropolitan area-regional city-functional area-new community", and form a diverse, open and open space system.

collaborative regional economic ecology.

If you zoom in, you will find that Chengdu and Chongqing are currently promoting the construction of the "Chengdu-Chongqing twin-city economic circle" and accelerating the urban integration development of Chengdu, Germany, Meizi and Zizi. This is also the "first move" in the construction of the Chengdu-Chongqing twin-city economic circle.

It is not only conducive to strengthening and optimizing the core functions of Chengdu, but also conducive to leading the in-depth implementation of the "one trunk and multiple branches" development strategy and realizing the organic integration of Sichuan Province's regional development strategy and major national strategies.

An important factor that determines the development of metropolitan areas is the commuting problem between the core city and surrounding cities.

“However, the development situation of the Chengdu metropolitan area in this aspect is an inversion of the two. It attaches great importance to the development of rail transit in the central city, while the suburban accessibility to surrounding cities is relatively backward. This not only causes the big city disease in the central city, but also slows down the resources.

Mobility of factors." Luo Ling, a member of the Sichuan Provincial Party Committee and Provincial Government Decision-making Advisory Committee, believes that the Chengdu metropolitan area should move towards the goal of being an on-track metropolitan area.

In the next step, the infrastructure construction of the Chengdu metropolitan area must not only solve the problem of "access", but also the problem of "speed" and form a 15-30 minute commuting circle.

This has also become a very important direction in the process of urbanization construction of Chengde, Meizi and Zi.

On July 27, the four local governments of Chengdu, Dezhou, Meizi and Sichuan Railway Industry Investment Group Co., Ltd. jointly signed the "Cooperation Agreement on the Construction and Management Framework of the Chengdu Outer Ring Railway".

The outer ring railway has a total length of approximately 450 kilometers and will connect the four cities more closely.

Deyang City is located in the northeast of Chengdu. It was established due to the layout of modern large-scale industries in the "Third Line Construction" and is a major technical equipment manufacturing base in China.

On August 14, a press conference held in Deyang City proposed that a transportation system of "9 high speeds, 13 fast lanes and 13 rail transits (9 expressways, 13 express lanes and 13 rail transit)" should be built to create "Chengdu City".

"The best city for commuting".

Some experts said that Deyang’s move is to further accelerate its integration into Chengdu and become a sub-central city in the Chengdu metropolitan area.

In addition, the planning blueprint for transportation construction in the Chengdu metropolitan area has been finalized.

Coordinate the layout of a multi-level and multi-standard rail transit network with Chengdu as the central hub, strengthen the connection of rapid transportation such as intercity and urban (suburban) railways in the four cities, and accelerate the construction of the Chengde, Chengmei, and Chengdu urban (suburban) railways and the Chengdu outer railway.

Rail transit projects such as the Ring Railway will open up high-speed rail corridors such as the Chengdu-Chongqing Middle Line, Chengda-Wanzhou, and Chengdu-Ziyi, and promote the "four-network integration" of trunk railways, intercity railways, municipal (suburban) railways, and urban rail transit, and build a 1-hour

Commuting circle.

Liu Lu believes that a single city has divisions and boundaries, but a metropolitan area has no specific geographical boundaries.

"We can plan, but the decision of who can finally enter the circle depends on the degree of economic development and industrial correlation." The development of the metropolitan area is a dynamic process. In the early stage, the core city takes the lead in development as a symbol, and by attracting various elements

, such as the gathering of people, finance (investment), and materials (projects) to enhance its competitiveness.

However, the essence of the economy is to pursue the highest rate of return on factors. Therefore, when the core city develops to a certain stage, investment capital will promote the natural flow of resource factors to the surrounding areas.

"Road network density and timeliness are the keys to the flow of resource elements." Liu Lu said that if the transportation links between Chengdu and surrounding cities are further strengthened, the scope of the Chengdu metropolitan area may continue to expand.

Liu Lu believes that the "high-speed rail" proposed by China for cities with a population of more than 500,000 has also increased the scope of resource flow. This will not only expand the radiation and influence of core cities on other regions, but also shorten the development process of metropolitan areas.

.

Metropolitan area is an economic geography concept, and urbanization is its specific requirement.

The four cities in the Chengdu metropolitan area are surrounded by the Longquan Mountains.

In the past, Longquan Mountain was a natural barrier, but after Chengdu announced that it would develop "eastwards" across Longquan Mountain, parts of Longquan Mountain were planned as urban forest parks.

An interesting formulation is that if the four cities form a "circle", Longquan Mountain in the middle will become the Central Park of the metropolitan area.

In the past, Central Park usually referred to a large public space in the core area of ??a city. From the perspective of a metropolitan area, considering a mountain as a Central Park actually reflects the determination of the four cities to integrate into the city.

However, the integration of the Chengdu metropolitan area has taken more than 10 years.
