Since the 18th National Congress of the Communist Party of China，The Party Central Committee attaches great importance to the development of the transportation industry，Make strategic arrangements to accelerate the construction of a transportation power。The Fifth Plenary Session of the 19th CPC Central Committee proposed to accelerate the construction of a strong transportation country、Improving comprehensive transportation channels、Integrated transportation hub and logistics network construction，Accelerate the bet365 mobile transit network in urban agglomerations and metropolitan areas。As a labor force、An important carrier for the flow of capital and technology in space，Transportation infrastructure promotes economic growth，In particular, regional resource integration and coordinated development play a key role。In recent years，my country’s high-speed bet365 mobile construction has entered a stage of rapid development，The total operating mileage in 2021 will reach 40,000 kilometers，Accounting for about 60% of the total mileage of high-speed bet365 mobile in the world，Far ahead of other countries and regions。The construction of high-speed bet365 mobile networks has significantly improved inter-regional accessibility，Improved the flow efficiency of production factors such as labor and capital，Become a new driving force for high-quality regional economic development。

　　Accelerate bet365 mobile enterprise renewal

　Different from other transportation infrastructure，High-speed bet365 mobile is mainly for passenger transport，Therefore, the connection of high-speed bet365 mobile will not significantly reduce the cost of non-labor production factors and commodity transportation。Theoretically，The impact of high-speed bet365 mobile on corporate income and costs is mainly reflected in two aspects。First，High-speed bet365 mobile connects the capital markets of different cities、Commodity market and labor market，Improve the production efficiency of enterprises in the city by generating agglomeration economic benefits；At the same time，Benefit from the space-time compression effect brought by high-speed bet365 mobile，The time cost of communication between cities is reduced，Improvement of market accessibility in high-speed bet365 mobile cities。Second，High-speed bet365 mobile brings the entry of enterprises and labor force，Land demand and price increase，Labor wages increase due to increases in production efficiency and cost of living。In order to maximize profits，Enterprises will face a trade-off between improved efficiency and increased costs。

Of course，The attractiveness of high-speed bet365 mobile to enterprises will also vary depending on the industry and city’s endowments。On the one hand，From an industry perspective，High-tech industries (such as software development、Biomedicine) invests more in capital and high-skilled labor than ordinary manufacturing，The dependence on land is lower；Opposite，The production activities of low-end manufacturing rely more on building factories and hiring a large number of low-skilled labor。Therefore，Technology-intensive and information-intensive industries will benefit more from the agglomeration economies generated by high-speed bet365 mobile。On the other hand，As the main factor affecting corporate location selection，Land prices are affected by the elasticity of urban land supply。When supply elasticity is small (such as geographical factors or land use planning constraints)，The increase in land demand brought about by the influx of enterprises and labor will lead to a larger increase in land prices，At this time, most of the dividends from agglomeration economic benefits are captured by real estate developers，Not conducive to the development of the enterprise；Vice versa。For cities located at the edge of the transportation network，The increase in market potential may not offset the increase in costs caused by the increase in land prices，Therefore，Enterprises that are highly dependent on land factors，When selecting sites, we will avoid high-speed bet365 mobile edge cities with limited market potential。

The author’s findings are based on research on industrial and commercial enterprise registration data in 280 cities across the country from 2000 to 2017，The opening of high-speed bet365 mobile has increased the number of newly registered enterprises per 10,000 people in the city by 1.76，But it will also cause about 0.Exit of 32 companies，The number of net new companies per 10,000 people is 1.44，Equivalent to 6% of the net increase in urban enterprises during the same period.26%。

　bet365 mobile gathering of talent space

　For the labor force，High-speed bet365 mobile brings transportation convenience、Rising wages and housing costs。On the one hand，High-speed bet365 mobile can improve the livability of cities，Improve residents’ living utility；Furthermore, high-speed bet365 mobile can increase nominal wages by improving the production efficiency of enterprises，Attract labor force to move in。But on the other hand，The influx of labor force increases housing demand，Housing prices rise，The increase in living costs will squeeze out part of the labor force。In order to maximize utility，Labor needs to weigh the above costs and benefits。From the perspective of labor force skill differences，Highly skilled labor forces pay more attention to the convenience of urban infrastructure when selecting locations，At the same time，High-speed bet365 mobile connectivity can significantly improve the production efficiency of high-tech enterprises and the nominal wages of high-skilled labor force，These are all conducive to the concentration of high-skilled labor in high-speed bet365 mobile cities。In addition，The elasticity of housing supply in a city will also affect the attractiveness of high-speed bet365 mobile cities to the labor force。Based on theoretical analysis，In cities with greater supply elasticity，The scale of labor inflow is larger、Slower wage growth、And output grows faster。Therefore，Low-skilled labor whose nominal wages are less affected by high-speed bet365 mobile may avoid cities with less elastic housing supply when choosing locations。

The author’s research findings are based on the national college student employment survey data and the national floating population dynamic monitoring data，The opening of high-speed bet365 mobile has significantly increased the proportion of college students seeking employment in cities0.08 percentage points，Equivalent to 11% of the new employment ratio of college students in the city during the same period.76%，But at the same time, there is a certain crowding out effect on low-skilled labor。For cities of different levels，High-speed bet365 mobile has significantly improved by one、The attraction of second-tier cities for college graduates，At the same time, it squeezes out some low-skilled labor force；ER三、The labor employment structure in fourth-tier cities has not changed significantly with the opening of high-speed bet365 mobile。Specially，In cities with greater elasticity of housing supply，The opening of high-speed bet365 mobile will make it more attractive to highly skilled labor force，At the same time, the smaller the crowding out effect on low-skilled labor；Opposite，Cities with less elastic housing supply may face a sharp increase in housing prices after the opening of high-speed bet365 mobile，Thus causing some low-skilled labor to leave。

　　Promoting the upgrading of bet365 mobile

High-speed bet365 mobile not only facilitates people’s travel、Non-business travel such as visiting relatives，It also reduces the time cost of business travel，Significantly increase the population flow of the city。According to statistics from China Railway Corporation，High-speed bet365 mobile passenger volume reached 22 in 2019.900 million visitors，Accounting for 62% of the country’s railway passenger traffic.6%，About 6 times more than in 2010。The increase in passenger flow has brought about a large amount of consumer demand，So as to promote local industries，Especially the development of the service industry。Also，The decline in transportation costs also helps investors expand markets and seek cross-regional cooperation opportunities，Having an impact on the city’s industrial structure。

Depending on the connecting city，The impact of high-speed bet365 mobile on the industrial structure of various cities may be quite different，Can be summarized into the following three types。First，Division of labor effect—cities connected by high-speed bet365 mobile develop industries based on their comparative advantages，Growth through trade。Regions with relatively backward industrial structures can use their comparative advantages to undertake some industries from other cities，Or further strengthen the development of advantageous industries through knowledge spillover and technology exchange。In this case，High-speed bet365 mobile accelerates the division of labor and specialization between regions，Enable the two cities to expand the scale of their leading industries，In the short term, the industrial structure will develop towards polarization。Second，Convergence effect-connecting to the high-speed bet365 mobile network allows cities to face larger factor and product markets，The increasing market overlap between different cities。In order to compete for high-quality resources、Make full use of the enhanced market potential of high-speed bet365 mobile，Cities may choose similar industrial structures。In addition，High-speed bet365 mobile attracts more immigrants by making it easier for people to travel，Brings new demands to this city；In order to cater to this new demand，There will be new investments on the supply side，Making the city’s industrial structure similar to the city where the foreign population comes from。Third，Learning effect - cities achieve coordinated development through the exchange of information and mutual learning，Improve urban production efficiency。In the context of the past where economic growth was the main goal，More developed cities often become role models for other cities to learn from。In addition，The company itself can also communicate through technical personnel、Field visit、Learn the advanced production technologies of other companies through patent citation and other methods，Promote the improvement of the company's production technology and the optimization of the factor input structure，Thus promoting the transformation and upgrading of the overall industry。

The author’s research findings using panel data of 280 cities at prefecture level and above in China from 2005 to 2019，The opening of high-speed bet365 mobile has significantly promoted the improvement of the urban industrial structure，The impact is 3 of the overall structural change.75%—4.84%。Heterogeneity analysis shows，When the initial industrial structures between connected cities are different but the economic development levels are similar，The division of labor effect plays a leading role，Resulting in the differentiation of industrial structures among cities；When there are differences in industrial structure and development levels between connected cities，Convergence effect dominates，Promotes the similarity of industrial structures；Affected by the "structural slowdown" phenomenon during the transition period，The learning effect from cities with a higher level of industrial structure to cities with a lower level of industrial structure is more obvious。
