With the acceleration of urbanization in China, the number of big cities is increasing. The measure of the size of the city, in addition to the central city population, urban built-up area is also an important indicator.

According to the definition, the completion of the area refers to the urban area has actually been a piece of development and construction, municipal utilities and public facilities with the basic area. The core of the city, it includes a contiguous part and scattered several already building plots, municipal utilities and public facilities in the basic region; on a multi City Town, which is composed of several contiguous development construction, municipal public facilities and public facilities in the basic area.

According to the first financial reporter before the Ministry of housing announced the "2015 City Construction Statistics Yearbook", according to the National Bureau of statistics statistics combing found that China has 49 City built-up area of more than 200 square kilometers, the city encompasses the main city and part of a second tier city large scale the three line of the city. Among them, Beijing, Shanghai, Guangzhou and Chongqing built-up area of more than 1000 square kilometers.

Beijing topped the list with 1401 square kilometers. At present, Beijing urban population (non resident population of the city) more than 18 million, the city's total area of about 16411 square kilometers, the current scale of urban and rural construction land in Beijing is 2921 square kilometers. In other words, the built-up area equivalent to nearly 1\/10 of the total area of the city, about half of urban and rural construction land.

Shanghai built area is currently lack of open and accurate data. Whether it is the Ministry of housing and Urban Construction Statistical Yearbook 2015, or the National Bureau of statistics data show that the built-up area of Shanghai is 999 square kilometers. However, the first financial reporter noted that in the historical data of the National Bureau of statistics, 2010 Shanghai built area reached 999 square kilometers, if estimated in accordance with the development situation of the past few years, Shanghai area has already exceeded 1000 square kilometers.

In particular, the scale of construction land in Shanghai has more than 3000 square kilometers, the urban population of Shanghai broke the 20 million mark, with reference to these two factors, it can be estimated that at present the actual situation of Shanghai area and is close to Beijing.

After the two strong first-tier cities, is in the southwest of Chongqing, the area has more than 1300 square kilometers, 1329 square kilometers, ahead of Guangzhou. But Chongqing is a municipality directly under the central government, the total population reached 30 million, equivalent to a medium-sized provinces in 2016, the urbanization rate reached 62.60%, that is to say, a city resident population of about 18000000, so the built-up area over Guangzhou ranks third.

That is, the built-up area data of the statistical yearbook, are calculated by the city, although some city built area is not small, but a large part of which is from the jurisdiction of the outer zone. The size and competitiveness of a measure of the size of the city, mainly to see the size of the main city. Generally speaking, the larger the size of the main city of the big city, the population density of the unit area is high, the land use is more intensive, the external radiation force will be stronger.

Data show that Chongqing has a total area of more than 82 thousand and 400 square kilometers, in addition to the city, there are more than and 20 suburban counties, urban area calculation, in 2014, the built-up area of Chongqing urban area of about 720 square kilometers, more than first-tier cities of Guangzhou Shenzhen and Tianjin is slightly smaller, roughly.

If the deduction is not far away from the outskirts of the space is not considered, the main city of the first tier cities in Guangzhou built-up area is roughly 1000 square kilometers. According to the Guangzhou Daily reported on March 2016, the Guangzhou City area in 2015 statistics "project acceptance will be held in Guangzhou City, the project to determine the built-up area of 1237.55 square kilometers, and for the first time in Conghua District of Zengcheng, included in the scope of statistics.

Data show that by the end of 2007, Guangzhou District ten (excluding Zengcheng, Conghua) the built-up area of 843.7 square kilometers; by the end of 2013, the number of 1023.63 square kilometers; by 2014, Guangzhou built area of 1035.01 square kilometers, 13.92 square kilometers in 2013 than the new. If it is not sixty or seventy kilometers away from the main city of Nansha District, the main city built area of about 1000 square kilometers.

Somewhat surprisingly, the "2015 Statistical Yearbook" in city construction, Dongguan built area reached 932 square kilometers, ranking fifth, even beyond the first-tier cities of Shenzhen, Tianjin, Wuhan, Chengdu and other traditional big city. This is a big reason lies in the area of the Dongguan area, not only the main city, but also under the jurisdiction of the township. Dongguan has more than and 20 towns, each town's total economy is equivalent to other places of the county, and even the city, and a large number of resident population, so the size of each township built-up area is not small.

If only the calculation of the main city, then the built-up area of Dongguan will be much smaller than Shenzhen and Wuhan, Tianjin and other big cities.

On the other hand, the traditional planned economy era of the central area of the city, the scale of the built area is relatively large. In addition to the four municipalities, Guangzhou, Nanjing, Chengdu, Wuhan, Xi'an, the district centers built area of more than 500 ordinary kilometers, Shenyang has reached 465 square kilometers, in all fifteenth city.

Ding Changfa, an associate professor of economics at Xiamen University, first financial analysis, the center of each district, such as the northwest, central, northeast and other regions of the central city, the administrative level is relatively high. At present the main resource of our country such as finance, education, medical and cultural resources and the administrative level is still closely related, the more the higher the level of city administrative allocation of resources, for example, at the beginning of the Central South University mainly concentrated in Wuhan, at the beginning of the Northwest University mainly concentrated in Xi'an, southwest Chengdu and Chongqing in the beginning. So the agglomeration effect of these cities is also bigger.

In Wuhan, for example, a lot of people who had studied in Wuhan, and later came to work in Guangzhou have a common experience: that is larger than the size of Guangzhou. This is a big reason lies in the early days of reform and opening up, the city of Wuhan on a large scale, before the row in Guangzhou.

"Wuhan taxi cheaper than Guangzhou, but I take a taxi to the gate of Wuhan University from Qiaokou, spent 65 yuan, the key is around the two places, are 80 of the last century, in 90s built the city, many old houses. And the money in Guangzhou basically can cross the main city." Currently, Mr. Zhang graduated from Wuhan University in Guangzhou said, Guangzhou is currently the center of Tianhe District, in the last century in 90s is a large area of farmland, not to mention Panyu, Luogang and other places, that is to say the twenty or thirty year expansion of the Guangzhou city faster than Wuhan.

In addition, different cities are subject to the relationship between topography and urban structure, urban area and the traditional concept of the size of the city will also be some deviation. In the city of Wuhan, the Great Lakes occupy a larger scope, which also affects the distribution structure and pattern of the city.

Most Jiangsu

From the distribution of the region, 49 city built area of over 200 square kilometers of the city, mainly in the eastern coastal areas there were as many as 28, northeast 5, Western 16, mainly is the capital city (including municipalities).

Provinces, Jiangsu up to a total of 7 cities, namely Nanjing, Suzhou, Wuxi, Changzhou, Xuzhou, Nantong and Lianyungang. In addition to Lianyungang, the total amount of GDP in the other 6 cities have exceeded the 500 billion mark, have also been allowed to build the subway.

After Jiangsu, Guangdong, Shenzhen, Dongguan, Shantou, Guangzhou and Huizhou are the 5 largest cities in the world.

Compared to the coastal areas, the central and western regions of the city are basically the capital city, only Luoyang is the only non provincial capital cities. This also shows that the Midwest urbanization level and city development level is still relatively low, in addition to the capital city, the built-up area population scale and other city agglomeration are relatively small, and there is a big gap between the eastern coastal.

For example, in Yunnan, Guizhou, Shaanxi, Gansu and Xinjiang, in addition to the provincial capital cities (autonomous regions), there is no other city built area of 100 square kilometers. The size of the city is generally relatively small, whether it is economic development or population agglomeration is far from the provincial capital gap.

In addition, there are 4 provinces city built area exceeded 200 square kilometers of the city, Hainan, Ningxia, Qinghai respectively and Tibet, common of the several provinces in the total population is below 10 million, the provincial capital (capital of the autonomous region) the size of the population and urban areas are relatively small.

Generally speaking, the higher the administrative level of the city, the population scale and the size of the city is also the formation of the larger. Data show that in the 49 City, is the capital city of the municipalities, and municipalities, and the general level city is only 17, in addition to Dongguan, Suzhou, Wuxi and Yantai, the other city's built-up area is between 200 to 270 square kilometers. In addition to Luoyang from the central, Daqing from the northeast, other cities are all from the eastern coastal areas.

However, although the rate of urbanization in the central and western provinces is relatively low, the average level of the city's smaller cities, but it also means no small potential. In particular, some industries such as Baotou, Liuzhou, itself has gathered a large number of industries and population, the current built-up area has been close to 200 square kilometers.

Hubei, Yichang and Xiangyang, built-up area has more than 160 square kilometers. In recent years, Hubei, Yichang, Xiangyang as the two deputy provincial center city development, interaction with Wuhan, the formation of a primary two deputy of the development pattern. With the accelerating pace of urbanization in the future and the development of the central and Western economies, the development of these industries, the general level of the city's population and urban scale will continue to grow.
