Urban spatial structure theories yield conflicting predictions—monocentric, polycentric, and agglomeration models emphasize different variable relationships—creating unresolved theoretical tensions. The core issue is insufficient systematic empirical testing of these competing theoretical predictions, which has resulted in fundamental questions about the relationships between infrastructure, economic development, population density, and urban growth patterns remaining unresolved. This ambiguity persists due to insufficient hypothesis-driven empirical research that simultaneously tests these varying theories. We apply this framework empirically using multi-source geographic big data—including nighttime light intensity and road network density—for 1847 county-level units in China over the years 2010, 2013, and 2016. Employing the concept of natural cities to transcend administrative boundaries, we define counties containing a single urban agglomeration as exhibiting smart growth, while those containing multiple agglomerations represent sprawl growth. Our empirical results reveal: (1) Road network density exerts the strongest positive effect on urban sprawl; (2) Economic development and population density also significantly promote sprawl; (3) Improved transportation accessibility significantly increases sprawl probability; (4) Population density mediates part of the total impact of road density on growth patterns; (5) Cities classified by POI functional types exhibit differing sensitivities to infrastructure, with public service-oriented cities most strongly influenced. The findings provide novel theoretical insights and empirical support for developing targeted, sustainable urbanization strategies.

Background:The 2022 Beijing Winter Olympics is a representative large-scale sporting event, which not only promotes the development of the national and regional economy, society, and culture but also increases the demand of residents for winter sports, thus helping achieve the grand goal of "encouraging 300 million people to participate in winter sports." This research explores the influence of the Beijing Winter Olympics on residents' demand for winter sports in the Beijing-Tianjin-Hebei and Yangtze River Delta urban agglomerations in China.Methods:Applying big data mining techniques, the Baidu Index of Winter Olympics-related terms are used to measure residents' interest in the Beijing Winter Olympics, and the ratio of the Baidu Index of five winter sports (ice skating, ice hockey, curling, luge, and skiing) to the number of internet searches is used to capture residents' demand for winter sports. Moreover, we explore the spatial-temporal pattern of the interest in the Winter Olympics and the demand for winter sports and construct an econometric model to test the driving effect of the Winter Olympics empirically.Results:The results show that 1) since 2011, interest in Winter Olympics has been on the rise, and the interest of residents in Beijing-Tianjin-Hebei has been higher than that of the Yangtze River Delta; 2) the demand for skating and skiing, which are two popular winter sports, shows a declining geographical concentration, indicating that the popularity of these two sports is on the increase; 3) the demand for winter sports in the peripheral cities in Beijing-Tianjin-Hebei shows a trend of specialization, while Beijing, Tianjin, and some cities in the Yangtze River Delta present a trend of diversification; and 4) the interest in the Beijing Winter Olympics influences the demand for winter sports positively.Conclusion:This study shows that the increase in interest in the Beijing Winter Olympics boosts residents' demand for winter sports, which implies that hosting Winter Olympics successfully drives winter sports participation in China.

Based on the Tencent migration big data, we use the social network analysis method to construct a network of inter-city tourism flows among 160 municipal districts and county-level areas in the Yangtze River Delta (YRD) of China and explore the network structure characteristics. The results show that holidays have a noticeable pulling effect on cross-city tourism. The tourism network of the YRD has basically formed four radial regional tourism sub-networks centered on Shanghai, Nanjing, Hangzhou and Hefei. The development of the tourism network in the YRD is in an unbalanced state, and the attraction of tourist flow between cities shows a polarization phenomenon. The attraction of tourist flow between neighboring cities in the agglomerative subgroup is stronger, and the attraction weakens with the increase in distance. Based on the above findings, the paper puts forward suggestions such as breaking down administrative barriers, improving infrastructure, and signing a series of tourism industry cooperation and development agreements.

By using questionnaire data and POI data, this paper analyzes the difference between residents’ demand and supply of public service functional facilities in Shanghai, and calculates the matching efficiency of supply and demand of functional facilities in each street and district of Shanghai. The results found that there are significant differences in the demand preferences of residents with different characteristics for public service functional facilities. The supply mismatch of public service functional facilities in Shanghai is widespread, showing the phenomenon of excess and insufficient supply of service resources. According to the mismatch of resources, streets and districts in Shanghai can be divided into 15 types of public service facilities. The paper puts forward strategies for governance from three aspects which are supply layout, supply information and supply subject. And provides reference frame for the renewal of community life circle and the improvement of the supply efficiency of functional facilities space.

高速铁路于20世纪70年代末在欧洲兴起后,在带来巨大经济效益的同时,也改变了欧洲的城市网络结构(张国华,等,2011;Chen C,Land Hall P,2011).自2008年京津高铁开通以来,我国高速铁路快速发展.2020年底,中国高铁运营里程数超过3.9万公里,占全球高铁运营总里程的七成以上.高铁在改变居民出行习惯和方式的同时,也对沿线地区的经济社会发展带来重大影响,受到学界广泛关注(Meng Xuechen,Lin Shanlang and Zhu Xiaochuan,2018).在高铁推动区域交通可达性和推动区域经济发展方面,多数国内外学者认为高铁对两者均有正效应.不过,在高铁如何对区域经济产生作用,以及如何改变沿线区域经济空间结构上,尚未有较统一的解释.在高铁对城市空间结构影响的研究中,一些学者分析了高铁对单一城市的影响(李磊,等,2019);有些学者则以中国整体的城市体系为研究对象(初楠臣,等,2018;刘承良,等,2019);也有部分学者以某一城市网络为例(方大春,孙明月,2015;韦胜,等,2019),但对高铁沿线区域多个城市网络结构的影响与塑造研究还较为少见(钟业喜,等,2019).

This paper measures the level of tourism internationalization of 50 major cities in Mainland China by analyzing their connectivity as international tourism hubs. A typology of cities is presented based on a comparison of their ‘product destination internationalization’ and ‘business environment internationalization’ in the tourism sector. Results are interpreted in the context of three dimensions of the internationalization of the Chinese economy: the imbalanced development of the space-economy; the uneven impact of policy plans and mechanisms; and the imprint of spatio-political hierarchies. We discuss how this study can be complemented with research using other spatial imageries, and used as the starting point for further comparative studies on tourism internationalization in other geographical contexts.

引言 城市群是区域经济社会发展到高级阶段的空间组织形式,发挥着国家经济重心和区域发展引擎的作用,已成为众多国家与区域发展战略的重中之重.经过改革开放40年以来的探索和发展,中国城市群作为国家城镇化“主体形态”的战略地位逐步形成.伴随这一过程,中国城市群研究起始于20世纪80年代,进入新世纪后其吸引了学术界越来越多的关注和研究,而对城市群的研究跨越经济地理、城乡规划、区域经济、公共管理等学科领域,从宏观的空间结构模式到微观的主体关系治理,取得了丰富的研究成果,研究热点也呈现多阶段的演变特征.当下我国经济、社会、生态发展进入新常态,城镇化则处于需要跨越中等收入陷阱、健康向70％爬坡的历史拐点,挑战与机遇并存,为城市群理论研究提供了“温故知新”的重要时间窗口期.为此,笔者对1980-2018年时间段内我国城市群研究文献进行梳理评析,以期厘清城市群研究脉络、总结城市群研究框架、呈现城市群研究热点、展望城市群研究方向,为中国的城市群研究和实践提供参考和启示.

利用全国县(区)、市、旗层面2006 ～ 2016年数据,采用PSM-DID的方法,实证检验出高铁设站具有邻近效应.实证发现,对站点城市的促进作用主要来源于对周边地区的“负邻近效应”,作用半径为距离站点30～ 110千米以内的地区;“负邻近效应”与城市异质性有关.站点周边地区市场规模较大,负邻近效应越小;进一步检验高铁设站促进经济增长的机制,对于生产率处于中间区域的地区促进效应更大.

On the basis that education can promote human capital accumulation,this paper aims to construct an education-production model to show the influence of hierarchical education(secondary education and higher ed-ucation)investment on economic grow th.Considering the time-lagged effect of education investment on human capital formation and national production,we use the total education funds investment processed by time-lagged effect to estimate the human capital accumulation to study the output effect of hierarchical education invest-ments.The results show that physical capital accumulation is still the main factor in determining China's na-tional economic output scale.Besides,both higher education(including higher vocational education)invest-ment and secondary vocational education investment can improve the national economic grow th,w hile the effect of secondary vocational education is comparably weak.Human capital accumulation is more rewarding than physical capital accumulation.Therefore,China should invest more resources into education,especially the vo-cational education,w hich has been marginalzed.

The role of high-speed rails (HSRs) in urban development remains a much-debated topic, especially with regard to their impacts on surrounding counties without HSR stations. In this study, we construct a theoretical model explaining the relationship between the opening of HSR stations and counties' economic growth. We investigate the effects of HSR stations on county development in China, applying the propensity score-matching difference in-difference method to county-level panel data for China from 2006 to 2014, and we examine whether and under what conditions a resource redistribution effect occurs. The findings are as follows. (1) HSR construction is conducive to the economic growth of the site area, with a promotion effect of 14%. (2) The primary source of this promotion effect is a resource redistribution effect in areas located within 30-110 km (26 min) from the station. This attractive radius significantly differs between coastal and inland areas, with the effect being greater in inland regions than in coastal regions. (3) This difference can be attributed to the heterogeneity of the surrounding counties; the larger the market size of the surrounding counties, the smaller the resource redistribution effect is, and vice versa.

长江经济带区域协同增长的关键在于明确沿江城市群内部城市间产业联系对其经济产出的影响.城市群内部城市间的产业联系会加强其间的知识溢出并分享超额利润,从而影响城市群的经济产出.分析城市群内部城市间产业联系对经济产出的影响机制,构建理论模型.针对传统引力模型的不足,采用行业间投入产出引力模型(IIG模型)估算了2001-2015年间长江经济带沿线城市群的产业联系,通过产业联系修正人力资本的有效性.采用非参数协方差矩阵估计方法验证了理论模型.分析结果表明,以传统引力模型估算产业联系时,无法验证产业联系对经济产出影响的正面作用,而使用IIG模型估算产业联系时则能验证,即验证了理论模型,也说明了IIG模型对引力模型改进的意义.

针对学界在研究产业集聚份额比例对经济产出影响时存在的不同观点,文章在分析城市产业集聚模式特征时,在产业集聚的份额比例之外加入反映相关产业集聚的相关关系系数.通过理论分析,指出一定程度相关性集聚对区域经济产出的作用是正向的,而在相关关系系数超过门槛后,其影响则是负向的,即该种影响是倒U型的,并以此为依据构建理论模型.以1998-2015年长江经济带109个地级以上城市为研究样本.通过数据检验,确定模型形式为个体固定效应,运用非参数协方差矩阵估计方法对样本城市进行经验分析,对理论模型的有效性进行了验证,验证了相关产业集聚对经济产出的“倒U型”影响.
