Thanks to the delivery of Aurora Big Data

In November 2018, the Beijing Municipal Government officially launched the eastern migration process. The opening of the Tongzhou City Sub-Center is expected to continue the migration of 400,000 people. With the observations of the city's large data, since 2017, we have seen that, to a certain extent, the urban population surrounding the main city from the central city of Beijing began to flow from a place where this eastward movement had begun.

This document is based on Beijing (2017 Beijing Statistical Yearbook Screen), 12 regions including Dongcheng District, Xicheng District, Chaoyang District, Fengtai District, Shijingshan District, Haidian District, Shunyi District, Tongzhou District, Daxing District, Fangshan District, Mentougou District and Changping District. it is selected. The population of the 12 districts constitutes 92.5% of the settled population in Beijing and divides the selected area into the Aurora database according to the 16,455 grid (hereinafter referred to as the guide) and then the settled population of the first half of 2017 and 2018. . Population density and mobility analysis in the region.

Analysis of population flow in Beijing

According to the mid-term evaluation report of the ğ Five-Year Plan for the Beijing National Economic and Social Development negatif, which was published in recent months, the statistical results show that the size of the population in Beijing in 1997 was the first negative growth since 1997. . This trend is more evident this year. As shown in the figure below, in 2018 the net population of six large urban areas in Beijing is negative, and the net outflow of the population in the Chaoyang District and Haidian District is more important. The net inflow population is mostly in the surrounding urban areas such as the Tongzhou District, Fangshan District and Shunyi District.

From here, we can easily see that the floating population in Beijing has moved to the surrounding urban areas. Aurora's urban data shows that the immigrant population in Tongzhou District and Shunyi District is mostly from the Chaoyang District, and that the population of the Fangshan District is mostly from the Fengtai District. it is mostly seen from the Shijingshan District and the migration of the Daxing District. The population is mainly in the Shijingshan region.

The demolition of the population of the six regions of Beijing City and the transition to urban areas is mainly due to the government-led functions and the transfer of industries. It will help solve the major problems such as inin big city diseases; during the development of Beijing and improve the basic functions of the capital, and solve the proper functions of the city center, Shunyi and Tongzhou. as a significant area to undertake. The development of the Daxing and Changping District is also expected to lead to a coordinated development of Beijing-Tianjin-Hebei.

Beijing residential heat network analysis

Using Aurora's urban big data, we have divided the 12th region of Beijing into multiple networks. Grills and surrounding grills are defined as housing hotspots above and above the average. In 2017 and 2018, by comparing the changes in the population settled in each network, three different categories of life categories of continuous hot spots, housing cooling zones and new hot spots are divided.

In general, in 2018 there are 1018 residential hotspot grids in Beijing, where 1009 grids continue to warm up the residential areas and other 9 new residential hotspot grids. In 2017, in addition to the 1009 grille, which continued to be hot in 2018, the 1406 residential hotspot grid had 397 grids with a lower residence temperature.

2.1 Continuous hot spots

Ongoing hot spots are predominantly on the Fourth Ring Road, as well as in parts of Xi Erqi, Wangjing, Tongzhou District, Changping District and Shunyi District. As the central city of Beijing and its core functional area, the region on the Fourth Ring Road remained warm and vibrant. Although Xi Erqi and Wangjing were outside the 4th Five-Year Ring in Beijing, large-scale technology companies such as Baidu, Lenovo and Ali gathered here, and more and more people gather and live here.

For many people living in Shunyi District and Changping County, these places are both a residence and a workplace, or they have good access to the workplace. As can be seen from the distribution map of the study meeting, the workplace of Shunyi District residents is usually located on the No. 15 subway line and northeast of Beijing, and the workplace of the resident population in Changping District usually runs along the Changping line. Xi Erqi, Zhongguancun and other places.

2.2 Housing cooling zone

Relatively, the housing refrigeration zone in 2018 is mainly located in Xihongmen, Fangshan, Capital Airport living areas, Shahe and other places. Based on Xihongmen, 23.7% of the population living in the region in the first half of 2017, left Beijing in 2018.

In Beijing, Hebei Province, Henan Province, Shandong Province, etc., is close to Beijing. They're going to the regions. In terms of cities, Baoding City, Langfang City, Handan City, Tianjin City, etc. With more than 50% of the cities in Hebei Province, the cities flow to the top 20. Even though these people left Beijing, they still chose to fight in the Beijing-Tianjin-Hebei city community.

According to the mid-term evaluation report of the ğ Five-Year Plan for the Beijing National Economic and Social Development negatif, which was published in recent months, the statistical results show that the size of the population in Beijing in 1997 was the first negative growth since 1997. . This trend is more evident this year. As shown in the figure below, in 2018 the net population of six large urban areas in Beijing is negative, and the net outflow of the population in the Chaoyang District and Haidian District is more important. The net inflow population is mostly in the surrounding urban areas such as the Tongzhou District, Fangshan District and Shunyi District.

2.3 Adding hotspots

Aurora's urban large data is located near the Yizhuang line, from 9 new hot spots, to the southwest of Line 10, where Beijing is located at the southern end of the Daxing line. 39; Without exception, these new hot spots are close to the metro and nearby residents can travel directly to the city by public transport, such as the metro.

For example, by taking the three grids near the Yizhuang Line, people living on three grids work in the east and southeast of Beijing, especially around the Beijing Economic and Technological Development Zone, Panjiayuan and Guomao. It seems that public transport has a unique charm for people who choose residence.

Add a hot map of the working community at the hot spot in Yizhuang.

People who prefer to settle or settle from a particular location due to employment opportunities, public transport, government policies, and cost of living contribute to the development of the city by influencing the development of the history of the city and changes in the pattern. With the urban big data, we can clearly see the distribution of the settled population in Beijing and the flow of arteries, we can grasp the trend of urban development more accurately and provide constructive guidance for commercial site selection, housing selection and sensitive tourism.
