城市功能与地位转变的内在逻辑与实现路径

通过对世界国际性城市的研究梳理，提炼出城市功能驱使大城市地位转变的内在逻辑，构建了“战略功能-基础功能-城市地位”三者之间的作用模型。文章提出世界（国际性）城市功能可以分为战略功能与基础功能两类。其中，战略功能是驱使大城市地位转变的根本动力，在国家经济、区域布局中承担控制中心的角色。基础功能则是战略功能的重要外在表现，是维持和提高战略功能的重要保障，起到枢纽、节点的作用，能够提供高度现代化的基础设施与国际服务功能；同时也会间接影响战略功能的作用效果以及城市地位的转变。利用此逻辑框架，对杭州城市地位升级的实现路径进行了论证，识别出数字经济功能是杭州的战略功能，证实了数字经济的腾飞使得杭州发展迅速，城市地位提升，也回应了当下杭州进入“一线城市”的舆论呼声。

Inherent Logic for Municipal Functionality and Positionality Change and Their Methods of Implementation: A Case Study of Hangzhou

Since the beginning of the 21^st century, informationization and globalization have greatly impacted the development of cities. This was not the rapid growth of all cities within the national urban system, but the development of certain key cities linked to the process of globalization. In other words, the functions undertaken by cities determined their future development potential and status. The topic of “first-tier cities” is presently being debated in all sectors of society. Several media and research institutions have been racing to release series of rankings such as “new first-tier cities” and “quasi-first-tier cities,” in an attempt to continually re-rank the major cities in China. Behind such public opinion is a comprehensive consideration of the functions of a city, with an empirical understanding of its development potential and status. However, although different evaluation indexes directly affect the score of a city, there is currently no set or recognized system by which to conduct the evaluation of a city. This study explores the mechanism that influences urban status via a “theory to empirical” approach. By sorting the research on cities globally, this study extracted the internal logic by which urban functions drive the change in the status of big cities and constructed a role model for “strategic function–basic function-city status.” This study suggests that the functions of international cities can be classified as strategic and basic, of which the former is the fundamental force driving the status changes of big cities. Big cities play the role of a control center in national economies and regional layouts and can create a regional influence in areas including economic, financial, political, trade, information, and scientific innovation functions. The basic function of such a city is an important external manifestation of its strategic function and guarantee of the maintenance and betterment thereof. Big cities play the role of a hub and node, that can provide highly modernized infrastructure and international service functions that will simultaneously and indirectly impact the effect of their strategic functions and the transformation of their status. Using this logical framework, this study demonstrates the path by which the urban status of Hangzhou is being upgraded, identifies the functioning of a digital economy as the strategic function of this city, confirms the rapid development of the former and the promotion of the urban status of the latter, and responds to public opinion that Hangzhou is now a “first-tier city.” By introducing the concept and characteristics of strategic functions, this study highlights and emphasizes the importance for the rapid development and status upgradation of big cities in China. The development of such cities need to judge other cities worldwide, based on their own advantages. With a leading edge such cities can join the globalized system, conform to the scientific and strategic function of global development trends in a reasonable way, and stand out from others. Furthermore, with new “city business card”, such cities can enter the fast lane of benign development.
