高速铁路对中国省会城市旅游经济联系的空间影响

研究高速铁路影响下的中国省会城市旅游经济联系的格局、特征,对于当今在"一带一路"国家倡议背景下,客观解读高铁在省会城市间旅游一体化发展中表征的角色和政策含义,有助于国家、不同城市群、不同地区层面合理布局与重构优化高铁旅游资源要素、为高铁黄金时代旅游的可持续发展提供科学依据,避免政府决策的盲目性,同时也为优化以高铁为核心的跨国旅游空间结构组织提供参考与借鉴。基于旅游经济联系强度模型,社会网络分析的网络密度、中心度、凝聚子群等探讨高速铁路影响下的中国省际城市旅游经济联系强度及其网络结构、特征、空间格局等,研究表明:(1)中国整体高铁旅游经济联系松散,尚未形成一种大规模或占有中国绝对影响地位的高铁旅游经济的集散场,总体呈现相对分散、孤立的空间格局,其中西部高铁旅游经济联系断裂显著,东、中部出现小范围区域或城市群尺度的"小集聚"现象,目前呈现中国东北、西部、东南与中南4个高铁旅游经济派系。(2)高铁旅游经济辐射区集中在京沪、京广、沪昆高铁线交叉的地域,高铁旅游经济集聚区分布在京沪、京广、杭福深高铁线交叉的"金三角",胡焕庸线以南对旅游经济要素掌控程度大于以北地域,东北与西部高铁旅游经济辐射流动相对滞缓,整体呈长三角、京津冀、海峡西岸、长江中游等东部向中部继而向东北、西北与西南延伸拓展的态势。(3)高旅游经济联系强度的城市对相对较少,包括北京—天津、上海—杭州、上海—南京等,其中北京、天津、上海、杭州、南京等东部省际城市旅游经济综合强度位于全国前列,中部与东北省际城市居中,西部省际城市较为落后。

2020年中国省会城市和计划单列市政府网络透明度排名

数据来源:浙江大学公共政策研究院、浙江省公共政策研究院政府网络透明度是公众可以通过网络,能够了解政府日常在干什么、想干什么、为什么这么干和干得怎么样等信息。杭州、深圳、青岛、宁波、广州分别位列省会城市和计划单列市政府网络透明度的前5位,成都、福州、武汉、合肥、西安位列6—10位,28个城市分数超过60分。

中国西部省会城市新型城镇化发展水平演化研究

新型城镇化是以城乡统筹、城乡一体、产业互动、节约集约、生态宜居、和谐发展为基本特征的城镇化,主要表现在人口、经济、土地、社会和生态等方面。为揭示中国西部省会城市新型城镇化发展水平,从人口城镇化、经济城镇化、土地城镇化、社会城镇化、生态城镇化5个方面构建中国西部省会城市新型城镇化综合测评指标体系,利用熵值法和加权求和法计算各市2005—2019年新型城镇化综合得分、各因素层得分,并结合Q型聚类分析法及偏相关分析法对中国西部省会城市新型城镇化的综合水平、单项水平以及单项水平相关性进行分析。结果表明:(1)各市15 a间新型城镇化发展水平各异,区内及区际差异大。(2)各市人才吸引力较弱,经济及社会发展不均衡,城市建设力度大,生态文明建设有待提升。(3)仅经济-生态实现了协调发展,且土地城镇化快于人口城镇化。研究结果为中国西部地区新型城镇化发展提供决策支持。

中国省会城市经济地理格局历史演变动力

作为美国经济中心的大城市通常不是行政中心,且它们作为首府城市之后都长不大。而当代中国的城市一旦变为首府,就会迅速扩大。中国自古以来就是如此,未曾变化吗?本文对此进行历史考察。历史时期中国的政治中心往往同时具有经济中心功能。

Urban Hierarchy of Innovation Capability and Inter-city Linkages of Knowledge in Post-reform China

The 2000s has witnessed increasing interests in cities′role of innovation in the era of knowledge-based economy.Compared with substantial empirical analysis on the world city hierarchy of innovation,this paper attempts to examine the national urban hierarchy of innovation capability in China,in terms of ranking systems,spatial pattern and inter-city linkages of knowledge during the post-reform period since the late 1970s.Based on quantitative analysis such as principal component factor analysis and clustering analysis,this paper identifies the five-tier hierarchy of in-novation,which is headed by Beijing and Shanghai,followed by the capital cities of each province and regional centre cities.The development of China′s urban hierarchy of innovation capability has been driven by such factors as the scale of innovation,scientific scale,innovation potential and innovation environment.The paper further investigates the inter-city linkages of knowledge measured by the number of co-authored papers among the cities.Beijing is positioned in the central position of the knowledge diffusion and knowledge cooperation innovation.More knowledge diffusion among high level cities has occurred than that among the low level cities as well as between the low level cities and high level cities,and provincial capital cities and the regional central cities.

Industrial Green Spatial Pattern Evolution of Yangtze River Economic Belt in China

We use the directional slacks-based measure of efficiency and inverse distance weighting method to analyze the spatial pattern evolution of the industrial green total factor productivity of 108 cities in the Yangtze River Economic Belt in 2003–2013.Results show that both the subprime mortgage crisis and ‘the new normal' had significant negative effects on productivity growth,leading to the different spatial patterns between 2003–2008 and 2009–2013.Before 2008,green poles had gathered around some capital cities and formed a tripartite pattern,which was a typical core-periphery pattern.Due to a combination of the polarization and the diffusion effects,capital cities became the growth poles and ‘core' regions,while surrounding areas became the ‘periphery'.This was mainly caused by the innate advantage of capital cities and ‘the rise of central China' strategy.After 2008,the tripartite pattern changed to a multi-poles pattern where green poles continuously and densely spread in the midstream and downstream areas.This is due to the regional difference in the leading effect of green poles.The leading effect of green poles in midstream and downstream areas has changed from polarization to diffusion,while the polarization effect still leads in the upstream area.

人口空间分布对国家审计质量的影响研究

地理因素在政治学、经济学等领域受到越来越多关注,而国家审计研究对此重视不足。本文论述了人口空间分布影响国家审计质量的理论依据,基于2012~2017年省级面板数据通过GIS建模、多元回归等实证检验了人口空间分布对国家审计质量的影响,研究表明:一省人口到省政府驻地的平均距离、省会城市人口占全省人口比重对该省审计质量有负向影响。其中后者的影响在不同计量方法下保持稳健。研究结论为国家审计质量影响因素研究提供了新视角,并为国家审计这一"免疫系统"的建设提供了借鉴。
