【摘要】：世界城市化经验表明,一国城市化进程是人口空间集聚度持续提高的过程。以单体大城市为核心、以发达交通网为基础、与周边中小城市实现同城化发展的大都市圈,是城市化向高级阶段发展后出现的人口空间集聚形态,目前发达国家大部分城市人口都已聚集在大都市圈。我国城镇化率已超过50%,进入"大都市圈化"发展阶段。大都市圈建设的关键性基础设施,是核心大城市紧密联系周边中小城市的通勤铁路网。我国到2030年需建3万公里通勤铁路,相当于全国现有铁路长度1/3。以低成本通勤铁路替代过度扩张的城市地铁,可节省上万亿元投资。城市化是我国最大内需所在,但外来人口融入城市的真实城市化进程滞缓,是造成内需不足、增长乏力的主要原因。通勤铁路引领的同城化大都市圈建设,能化解城市新移民"大城市进不去、小城市不愿去"两难困境,有效推进真实城市化进程,有力拉动投资和消费需求,极大提升我国城市集聚力、辐射力、创新力和竞争力,是经济稳增长、扩内需的强大引擎,是塑造国家竞争优势的利器和重器。当前需及早制定主要都市圈通勤铁路规划,尽快列为我国"十三五"时期建设重点。
[Abstract]:The experience of urbanization in the world shows that the process of urbanization in a country is a process of increasing the spatial concentration of population. The metropolitan area, which takes the single big city as the core, takes the developed traffic network as the foundation, realizes the development with the surrounding small and medium-sized cities, is the population spatial agglomeration pattern after the urbanization develops to the advanced stage. At present, the majority of the urban population in developed countries has been concentrated in metropolitan areas. China's urbanization rate has exceeded 50, entering the "metropolitan area" stage of development. The key infrastructure of Metropolitan area is the commuting railway network which the core cities are closely connected with the surrounding small and medium-sized cities. By 2030, China will need to build 30, 000 km of commuter railways, equivalent to a third of the length of existing railways. Replacing overstretched urban subways with low-cost commuter railways could save trillions of dollars in investment. Urbanization is the biggest domestic demand in our country, but the slow urbanization of the foreign population into the city is the main cause of insufficient domestic demand and weak growth. The construction of the urbanized metropolitan area led by the commuter railway can resolve the dilemma that "big cities do not enter, small cities do not want to go", effectively promote the real process of urbanization, and have the power to stimulate investment and consumption demand. It is a powerful engine for steady economic growth and expanding domestic demand, and a powerful weapon and a heavy weapon for shaping the competitive advantage of our country. The urban agglomeration, radiation, innovation and competitiveness of our country are greatly enhanced, and it is a powerful engine for steady economic growth and expansion of domestic demand. At present, it is necessary to draw up the commuting railway plan of the main metropolitan area as soon as possible and make it the key point of the construction in the 13th Five-Year Plan period of our country.
