The Impact of Digital Finance on High-Quality Development of the Chengdu-Chongqing Economic Circle

This paper developed a comprehensive evaluation system that was able to quantify the levels of high-quality development across the cities within the Chengdu-Chongqing economic circle,and investigate the impact that digital finance had on the cities’high-quality development and the underlying mechanisms through which it achieved this.This comprehensive evaluation system was constructed using statistical data from these cities for the period 2014 to 2020 while also taking China’s high-quality development philosophy into account.The key findings revealed that:(a)Digital finance was able to significantly promote high-quality development in the Chengdu-Chongqing economic circle;(b)Digital finance had a significant positive effect in promoting innovative,coordinated,green,open,and shared development;(c)Digital finance was able to stimulate the high-quality development in the Chengdu-Chongqing economic circle by boosting entrepreneurial dynamism;(d)Digital finance had a significant impact on the high-quality development of the axis areas,while its impact was less discernible in non-axis areas.The insights from this research offer a deeper understanding of the factors that drive high-quality development,the role digital finance plays,and the mechanisms through which digital finance is able to propel high-quality development at the city cluster scale.

Environmental influence of Wuhan urban agglomeration development and strategies of environmental protection

In Wuhan urban agglomeration （WUA）, the population growth and concentration, the industrial development and urban sprawl have been affecting the environment ftmdamentally. Comparing with Yangtze delta metropolitan region, the level of urbanization and industrialization of WUA has lagged behind for about 10 years; but the problems in environmental protection and rehabilitation are commonly serious. In the future, WUA should avoid unnecessary mistakes and seek a win-win strategy for economy and environment in its large-scale development stage. Based on the analysis of the changing of main environmental pollutants and the coupled curves in past decades, the paper discussed the important links among the urban environmental pollutions, industry growth and urban sprawl in WUA. It is concluded that the integration of economic and environmental policies in urban development is more required and significant at the large urban agglomeration region. Four proactive and long-term strategies need to be adopted to provide prior guidance and better protection for the development of WUA.

Sustainable Development of Wuhan City Based on Methods of Conventional Ecological Footprint and Emergy Ecological Footprint

This article uses the conventional ecological footprint method and its improved model of ecological footprint to analyze the state of the sustainable development of Wuhan City in 2009, the results show that the per capita ecological deficit calculated by the method of emergy ecological footprint is 3.8629 hm2, and the per capita ecological deficit calculated by the method of conventional ecological footprint is 2.0169 hm2. The results obtained by the two methods respectively show that current development of Wuhan is unsustainable. The emergy ecological footprint method introduces the energy flow to reflect the relationship between human resource demand and supply of nature to human and adopts parameters—emergy conversion rate and energy density to calculate the ecological carrying capacity data which is more accurate.

With the tide of economic globalization and the practice of“One Belt and One Road”Initiative,Sino-foreign cooperation has gradually become one of the effective ways to improve the quality of higher education.This paper based on the statistics and analysis of the data released by the Ministry of Education’s foreign-related supervision information platform,combining with the actual investigation and research on the situation of Sino-foreign cooperation of higher education in municipal universities of Wuhan,has found that the Sino-foreign cooperation programs commonly have problems of non-standardized enrollment of students,insufficient quality of teachers and teaching qualities,and lack of core competitiveness.Therefore,it is essential to upgrade the level of foreign cooperative institutions and the standards of students’recruitment,optimize the curriculum,pay attention to the public welfare of education,improve the teaching model,improve the level of teachers,so as to truly realize the original intention of Sino-foreign cooperation in municipal universities of Wuhan.

Several Thoughts on the Green Development of the Economic Circle around Mount Qomolangma

The Economic Circle around Mount Qomolangma is an economic spatial structure with Mount Qomolangma in the center of a circle with echelon extensions. There exist various effects and laws like the peaks of pyramid effect, the cultural source effect, the ecological butterfly effect, the law of value gradient distribution, and the inverse law of diminishing marginal utility. The Himalayas are the "Shenque"(which is believed to be the most secret and crucial acupoint for humans) of the Earth, and the "brain" of human beings. We must make the protection of the Himalayas a common task for all humans and establish the theory that the area around Mount Qomolangma should be regarded as the model and base of green development. The ten countries around Mount Qomolangma should build a partnership for green development and take a green lowcarbon path for sustainable development.

数字经济赋能成渝地区双城经济圈制造业高质量发展

基于2008—2020年成渝地区双城经济圈的城市数据,采用CRITIC-熵权法与TOPSIS相结合的方法测算数字经济发展水平和制造业高质量发展水平,考察数字经济对成渝地区双城经济圈制造业高质量发展的影响。研究表明:第一,数字经济能够显著推动成渝地区双城经济圈制造业高质量发展,该结论在经过一系列稳健性检验后依然成立。第二,数字经济对制造业高质量发展的推动效果在技术创新水平较高的地区表现得更为明显;此外,数字经济推动了流域地区制造业高质量发展,但现阶段并不利于非流域地区制造业的高质量发展。第三,数字经济显著提升了成渝地区双城经济圈制造业的创新能力和质量效益,但在促进制造业绿色发展和提升制造业产业基础能力方面并不明显。为此,应发挥成都、重庆双城辐射带动作用,促进成渝地区双城经济圈数字经济与制造业深度融合,增强成渝地区双城经济圈制造业区域协同发展力度,夯实成渝地区双城经济圈制造业高质量发展数字基础。

成渝地区双城经济圈区域协调发展的理论逻辑、实践创新与优化路径

成渝地区双城经济圈建设是深入贯彻党的区域协调发展战略、扎实推进中国式现代化的重要实践途径。成渝地区历经从经济区建设到城市群发展、再到双城经济圈构建的区域协调发展实践进程,基于对跨域治理需求的现实考量,通过调整府际关系、强化地方政府间合作、构建横向行政协调机制,以突破行政区划限制、促进区域资源优化配置、实现风险共担和利益共享,从而推动经济社会、生态环境等层面的均衡发展。新时代十年成渝地区双城经济圈在合作领域、协调机制、利益共享、政策执行方面创新制度体系,实践混合共力型的区域协调发展模式。但是未来在区域规划、利益格局、组织协同、资源配置上成渝地区双城经济圈建设仍面临诸多阻碍因素,需要从理念重塑、外部支持与内部保障三个维度进行路径优化。推动成渝地区双城经济圈建设向高质量阶段迈进意义重大,进一步从规划层面、执行层面、效能层面探索制度措施和协作策略,为形成各具特色、优势互补的区域发展新格局提供实践经验和路径借鉴。

成渝双城经济圈职业教育协同提升的现实审视与困境突破

作为与产业发展和民生就业关系最紧密的教育类型,职业教育协同发展是区域协调发展的重要举措。成渝双城经济圈职业教育协同提升已经具备充分的认知动力,包括由经济利益驱使、团队协作、管理调控需要等构成的外源动力及区域发展需要构成的内源动力。协同理论作为成渝双城经济圈职业教育协同提升的理论向导,对标首都经济圈进一步发现成渝职业教育协同提升过程中存在的现实困境,提出战略顶层设计、资源同城共享、产教同化激励、健全共同体平台等实践路径,以期为相关决策的制定与落实提供方向指引。

长江经济带上中游地区城市工业生态效率时空演变及驱动机制——以成渝经济圈和武汉都市圈为例

实现最优工业生态效率对促进工业绿色发展有着重要的现实意义。本文通过非期望产出的SBM模型,测度长江经济带上中游代表性地区成渝经济圈和武汉都市圈26个城市2010—2021年工业生态效率,通过Arcgis可视化工具对比分析其时空演变规律,并运用Tobit模型和地理探测器模型分别识别工业生态效率的驱动因素。结果表明:1)两个城市群工业生态效率整体均呈现波动上升态势,且与最优效率还存在一定的差距;2)城市群内部的地级市之间效率值存在少部分两极分化的现象;3)工业生态效率受科技研发投入、经济发展水平、交通可达性、对外开放水平等多个因素的影响,其中经济发展水平和交通可达性对于工业生态效率的提升起到较强的促进作用,对外开放程度与科技研发投入对于工业生态效率的促进作用还不明显,还需要进一步提高外商投资水平和增强科技研发投入质量以实现其对工业生态效率的正向影响。为此,通过强化城市群内外部的融合发展、构建协同创新网络和提升对外开放水平,以提高长江经济带上中游地区工业生态效率水平,促进地区高质量发展。

以行政协同治理推动区域协同发展——成渝地区双城经济圈协同推进机关事务标准化工作范例

随着区域协同发展政策战略地位的不断提高,区域协同研究正如火如荼,但现阶段学界尚有待阐明区域协同瓶颈之因并提出解决之法及相应的区域协同新机制。本研究试图聚焦于此,在理论层面梳理区域协同瓶颈产生机制与区域协同新机制,并对成渝地区双城经济圈协同推进机关事务标准化工作进行案例分析与问卷调查,在实证层面检验本研究的两个理论框架。案例分析发现,以机关事务为例,成渝地区双城经济圈存在治理尺度差异,这与中央政策调控共同构成协同的内外动机,驱动成渝地区深化合作意愿,卷入区域协同;与此同时,地方保护主义现象在两地机关事务标准化协同工作中亦有所披露,并阻碍了成渝地区双城经济圈建设的协同发展。问卷调查数据进一步验证案例分析结果:推进协同地区加强行政治理协同、推进治理尺度统一具有紧要性,成渝地区双城经济圈建设推进标准化执行助推区域协同发展,标准化的行政治理协同增强了成渝地区双城经济圈协同互信意识,在一定程度上消解行政壁垒和地方保护主义;此外,当前成渝地区双城经济圈建设干部协同卷入的奖惩机制不完善,行政治理协同还需大力推进,两地协同仍有较强的地方本位意识。基于此,本研究认为,地方保护现象是长久以来中国实行区域分治所衍生的治理产物,消弭地方保护主义、强化区域一体化思维成为协同瓶颈破局之必然要求,而基于行政尺度视角出发的行政协同治理则可能通过为地区卷入协同建构与区域空间相适配的治理尺度,从而成为区域协同必然的路径选择。并且,协同是基于时间矢量上不断发展变换的过程,地方政府应当通过牢牢把握不同阶段中区域协同“动机—路径—目的”三核心元素以寻求合理的区域协同合作。

武汉都市圈协同创新时空特征、影响因素及对策研究
