Measurement of Urban Economic Gravity of China’s Three Major Agglomerations and Its Implications for the Coordinated Development of the Beijing-Tianjin-Hebei Region

This paper adopts the perspective of urban economic linkage and the modified urban economic gravity model to conduct a comparative analysis of the economic gravity among cities in China’s three major urban agglomerations,including the Beijing-Tianjin-Hebei region,the Yangtze River Delta,and the Pearl River Delta.The results show that,despite the ever-tightening economic linkages among cities in the urban agglomerations,the development of the Beijing-Tianjin-Hebei region falls behind that of the Yangtze River Delta and the Pearl River Delta in terms of coordination,closeness,and balance.The economic linkages among cities in the Beijing-Tianjin-Hebei region are not as cohesive as they could be and display a significant“siphon effect”through Beijing and Tianjin as well as a prominently unidirectional economic flow.This study suggests that efforts should be put into directing the orderly flow of resources from Beijing and Tianjin to cities in Hebei and promoting a balanced economic flow among cities,thus facilitating the coordination of regional development.

Under the background of the coordinated development of beijing-tianjin-hebei model description of higher vocational education in hebei province

The concept of integration of Beijing Tianjin Hebei has been proposed for more than ten years, long-term since the region in a ＂how to integrate resources, practice and achieve common development＂ , but as ＂Beijing insurance＂ thought influence, allowing the emergence of unequal opportunity around the area, so that there is a substantial difference between the allocation of resources. This year on the eve of NPC and CPPCC Xi Jinping, general secretary of the phrase ＂to break a mu 3 distribute land thinking＂ , make the Beijing Tianjin Hebei collaborative development rise as a major national strategy, integration of Beijing Tianjin Hebei metropolitan area has become represent the general trend. This paper mainly through the study of Beijing Tianjin industrial transfer, analysis of the way of cultivating high skilled talents in Higher Vocational Colleges in Hebei Province, with the regional economic development better service in Beijing Tianjin hebei.

Evaluation on Agricultural Regional Coordination Degree of Beijing,Tianjin and Hebei

According to the characteristics of agricultural system in Beijing,Tianjin and Hebei,population pressure,resource utilization and construction capability are taken as the first grade indices.And there are a total of 14 second grade indices,such as the per capita cultivated land,per capita grain yield,per capita meat product,per capita aquatic product,per capita fruit,per capita water resource,per capita GDP,multiple cropping index,and proportion of agricultural expenditure in financial expenditure.An evaluation theory system for the coordination degree of agricultural system is established;and the empirical study on the agricultural coordination degree of Beijing,Tianjin and Hebei is carried out.Result shows that agricultural cooperative development in Beijing,Tianjin and Hebei is still in its primary stage.It is put forward that ideology is the premise,plan should take the lead,transportation is the foundation,and enhancing the brand is the key.Countermeasures are put forward for the agricultural cooperative development in Beijing,Tianjin and Hebei,such as enhancing the sense of strategic positioning during agricultural cooperative development in Beijing,Tianjin and Hebei,promoting the agricultural cooperative development planning in Beijing,Tianjin and Hebei,establishing a modern and integrated transport network system,strengthening the agricultural science and technology support,and improving the grade of agricultural products.

Problems and Countermeasures of Beijing-Tianjin-Hebei's location

Regional economic integration is the main trend in the world,the region participate inthe international competition as a whole.China has formed Yangtze River Delta and Pearl River Delta region which have showed strong competitive and plays an important role in enhancing theoverall competitiveness of a country.As the third largest area,Beijing-Tianjin-Hebei'slocation is very important,Beijing,Tianjin and regional development has also attracted great attention of national leaders,China will enhance the economic development of Beijing,Tianjin region to the national strategic level,However,the process of economic integration in Beijing,Tianjin and regional development has been relatively slow,Hebei Province in Beijing and the day Tianjin two big cities have been developing weak,Beijing City,but also faced with the problem of excessive development,This paper points out the problems faced by the integration of Beijing,Tianjin,and puts forward some countermeasures,hoping to discuss how to promote the integration process.

Visual simulation of regional development differen- tiation in Beijing-Tianjin-Hebei Metropolitan Region

Regional development differentiation is a complicated spatial and temporal dynamic process. Recent developments in spatial statistics and Geographic Information Systems （GIS） have led to an increasing interest in quantitative analysis and visualization of the process. However, so far, few direct qonnections have been made between the newly developed methods and classic spatial development theories, which would be very helpful for the inter- pretation and understanding of regional spatiotemporal differentiation. Using basic concepts and academic principles of polarized growth theory and gradient transfer theory, this paper quantifies the concept of regional development space. It then proposes a method based on GIS to visually simulate and analyze regional development spatiotemporal differentiation through a case study of the Beijing-Tianjin-Hebei Metropolitan Region （BTHMR）, China. The main research results are as follows. 1） The proposed method, built on classic theories and well-developed GIS technology, presents a good picture of regional development spatiotem- poral differentiation. 2） The levels of regional development, in terms of per capita GDP across BTHMR, diminished significantly with increased distances away from city propers （which can be seen as the regional growth poles）, leading to the appearance of development valley zones between different cities. The development valley zones between each city coincided with their boundary areas, which indicates that administrative boundaries have some impact on regional development, if the regional division is based on administrative boundaries. 3） From 1993 to 2007, the development level in the whole BTHMR improved significantly, of which polarized growth was dominant, especially for Beijing and Tianjin. However, as the two economic development engines in BTHMR, the pull effects of both Beijing and Tianjin on their peripheral areas were comparatively weak, except for those on Tangshan. 4） The structure and pattern of gradient transfer and balanced development in the BTHMR had not been completely developed yet, and the sustained polarized development of the regional economy in BTHMR was still going to be the main trend in the next 5-10 years.

京津冀协同发展战略实施十年回顾及展望

京津冀协同发展是重大国家战略。经过10年来的发展,京津冀协同发展已迈入高质量协同发展阶段,在科技创新、空间布局、生态保护、对外开放、民生领域等方面取得一系列显著成效,但也存在创新转化能力不足、产业转移承接断层、“过密过疏”现象突出、生态联合治理及生态补偿机制有待完善等挑战。面向中国式现代化建设的先行区、示范区这一目标任务,应进一步完善顶层制度设计和空间功能布局,以新质生产力为协同发展的新引擎,让数据要素成为协同发展的新动能,推动京津冀协同发展迈向更高质量、更高水平。

京津冀协同发展战略的空间结构评估与政策优化

“一核双城三轴四区多节点”是京津冀协同发展战略的重要空间支撑。2014年以来,京津冀城市群空间形态结构初步形成,“一核”中心性短期上升,“双城”融合趋势明显,京津发展轴逐渐向“菱形”城市化区域拓展。但从功能结构来看,北京的核心辐射带动能力还有待提升,北京与天津差距持续拉大,“三轴”的产业与人口集聚力尚需增强,“四区”的协调度和多节点综合承载力也有待完善。整体来看,京津冀城市群的空间结构尚停留在形态建设层面,空间功能还有待进一步发挥。未来,应形成“一主两副、三圈耦合、四轴四区、多中心”的空间结构,把石家庄建设成为京津冀的副中心,促进京津冀三大都市圈耦合协同,将“三轴”拓展为“四轴”,大力培育具有“二传手”功能的区域性中心城市,支撑京津冀协同发展战略长期目标的实现。

高质量发展视角下京津冀一体化测度与推进策略

推进京津冀高质量一体化发展,对于构建新发展格局意义重大。研究发现,京津冀地区呈多线程复杂网络形态,但大部分城市之间的联动发展指数较低,区域联动网络结构较为脆弱,区域一体化水平较低。其原因主要是区域内部城市体系不合理、产业互动性不足以及叠加制度性壁垒等。为推进区域一体化发展,京津冀三地应优化空间布局,深化产业分工合作、增强产业间联系,破除制度性壁垒、畅通要素流动渠道。

京津冀地区大气污染物与二氧化碳的协同减排分析

推进减污降碳协同增效成为社会经济高质量发展的客观要求。基于协同控制效应坐标系、单指标协同减排弹性和协同减排协同度等多维度协同减排分析方法,对2013—2019年京津冀地区CO_(2)排放量与SO_(2)、NO_(x)、烟粉尘的排放特征和协同减排水平进行综合评价。结果表明:(1)近年来,京津冀地区的CO_(2)排放量整体上处于增长的平台期,三类大气污染物(SO_(2)、NO_(x)、烟粉尘)实现了不同程度的减排,然而与全国对比,京津冀地区减污降碳协同增效工作仍面临较大压力。(2)京津冀地区CO_(2)与SO_(2)、NO_(x)和烟粉尘三类大气污染物之间存在不连续的协同减排年份、不稳定的协同减排交叉弹性、中低程度的耦合协同度,反映了该区域协同减排程度均处于较低水平,尚未形成稳定的减污降碳协同增效状态。在绿色低碳高质量发展目标引领下,提出如下建议:(1)加快推动污染末端治理向源头治理转变,从源头上实现产业发展和能源消费的低碳化。(2)将产业结构优化作为推进京津冀减污降碳的主要途径,统筹规划项目布局和产能分配。(3)发展能源替代和节能减排,优化调整京津冀的能源消费结构。

京津冀协同发展政策对人口增长态势的影响——基于系统动力学模型的研究

在京津冀协同发展背景下,流动人口集聚态势变化将使不同区域的人口规模与结构发生变动。应用系统动力学模型不仅可以模拟社会经济因素对人口增长产生的影响,还可以模拟政策效应,分析不同政策方案对京津冀人口增长态势的影响。模型不仅纳入了人口、经济与资源环境子系统的众多参数,厘清了京津冀协同发展过程中系统内要素的反馈过程,还依据北京疏解产业产值比衡量疏解政策强度并设计了政策参数,模拟了高方案、中方案、低方案以及技术进步方案下京津冀的人口增长趋势。应用灵敏度检验验证了模型的稳健性。结果显示,不同政策方案下人口规模与结构的变动呈现出明显差异。具体而言,政策实施后随着产业转移与区域内劳动力集聚态势变化,北京未来常住人口规模将下降,这可以缓解城市的资源承载压力;天津、河北的劳动力供给则有所增加。在人口结构方面,政策实施后北京的人口老龄化水平将提高,天津、河北的人口老龄水平虽然在中期会降低,但是在远期则会提高。京津冀协同发展政策、技术进步与市场机制共同发挥作用,可以有效地调节城市人口增长。文章的政策含义是,京津冀各地应依据人口增长的趋势实施差异化、动态化的政策,不断提升资源环境承载能力,以实现区域人口合理分布、经济发展、生态安全的目标。
