Problem B
Analysis and Decision-making of Regional Economic Vitality
and Its Influencing Factors
The regional (or urban or provincial) economic vitality is an important part of regional comprehensive competitiveness. In recent years, in order to improve the economic vitality, some regions have launched many preferential policies for stimulating the economy vitality, such as reducing the investment attraction approval steps, providing the capital support to start-ups and lowering the ttlement threshold to attract the talented. However, due to different resource endowments, the policies have different effects in different regions. How to ize the key factors and effectively improve the regional economic vitality is a worth study topic.
In order to study how to improve the regional economic vitality, we have obtained some data. Plea build a suitable model and solve the following problems bad on the data and your own data obtained through survey.
1. The regional (or urban or provincial) economic vitality is affected by variety of factors. Take
a region (or city or province) as an example, plea build the suitable relational model of influencing factors of economic vitality, and study the program of action to improve the regional economic vitality. Analyze the effects on the regional economic vitality change from the perspective of changing trend of population and enterpri vitality.
2. Select a region (or city or province), and analyze the short-term and long-term effects of economic policies transformation on the economic vitality of such region (or city ore province) bad on the suitable data surveyed by you.
3. Measuring the regional economic vitality is a complex issue. Plea lect the suitable index system, establish the mathematical model which analyzes and measures the regional (or urban or provincial) economic vitality, and rank the economic vitality of cities in Attachment 3.
4. If you are a decision-maker of regional economic development, according to the conclusions for Problems 1-3, provide a development proposal for the region (or city or province) discusd in Problem 2 so that the economic vitality in this region prents the benign sustainable development and the regional competitiveness is stronger.

The quantity of enterpris is an important index to measure the regional economic vitality. The quantity of enterpris has a direct effect on the available job opportunities, and to what extent the resource circulation is promoted, and decides the economic benefits. According to the data, from 2009 to 2018, there were 40,176,400 registered and established enterpris (excluding individual business, the same below) in total in 31 provinces/municipalities directly under the Central Government/autonomous regions (excluding Hong Kong, Macau and Taiwan Province). As of September 2019, 9,753,800 enterpris were cancelled (cancellation rate of 24.28%), and there were still 30,422,600 surviving enterpris. The quantity of enterpris which were registered and established from 2009 to 2018 and survive up in 2019 is as follows (Unit: 10,000):

Since 2013, the growth of quantity of enterpris in China has accelerated. Although the growth in different economic regions is obviously different, the annual quantity of newly-added enterpris in all regions is more than that of last year basically. In terms of region, except the total quantity, in the difference of average quantity of newly-added enterpris per province in four economic regions, the eastern region still maintains a great advantage: the provinces in the eastern region have the largest average registration quantity of enterpris per province and the highest growth, followed by the central region. In the west and northeast, the enterpri vitality is relatively weak. The average quantity of newly-added enterpris per province in the northeast may be surpasd by the western region in recent years. In general, there is still a relatively great difference in the enterpri vitality between regions. However, regardless of region, the annual quantity of newly-added enterpris from 2009 to 2018 was relatively stable.
Four economic regions are divided as follows:
Eastern region: Beijing, Hebei, Tianjin, Shandong, Jiangsu, Shanghai, Zhejiang, Fujian, Guangdong, Hainan
Central region: Shanxi, Henan, Hubei, Hunan, Jiangxi, Anhui
Western region: Chongqing, Sichuan, Guangxi, Guizhou, Yunnan, Shaanxi, Gansu, Ningxia, Xinjiang, Qinghai, Tibet
Northeastern region: Heilongjiang, Jilin, Liaoning, Inner Mongolia

If we look away from economic region and province, and focus on city, in addition to Beijing, Shanghai, Guangzhou and Shenzhen, the cond-tier cities are also worth attention. The data of stock and cancellation distribution of enterpris in Beijing, Shanghai, Guangzhou and Shenzhen and some cond-tier cities are given as follows. (Unit: 10,000)

The registered capital is an index to measure the enterpri size. In the distribution of enterpri size, there is not so large difference as imagined between the cond-tier cities and Beijing, Shanghai, Guangzhou and Shenzhen. The distribution data of registered capital of enterpri entity are given as follows:

How to narrow the difference in the quantity of enterpris between the cond-tier cities and Beijing, Shanghai, Guangzhou and Shenzhen? “Investment attraction” and “talent attraction policy” may be common methods. Therefore, the “talent attraction” between cities prently becomes increasingly fierce. In fact, the resident population in a region is cloly related to the quantity of enterpris in this region. The data of resident population in 2019 are given as follows.
