The Use and Abuse of Economics in Land Use Decision-Making in South Florida: An Industrial Park & Its Alternatives, 2020-2023

This paper reviews the economic methodology used to justify a proposed 357 hectare (800 acre) Industrial Park that would breach the Urban Development Boundary (UDB) in Miami-Dade County, Florida, a boundary that had been established to constrain urban sprawl and protect the surrounding wetlands and farmlands. We will examine the socio-economic setting of the region, the ownership of the farmland parcels designated to become industrial sites, and the misuse of the promoters’ narrow economic analysis. Then we shall explain and compute correctly the likely job creation based on the author’s own survey of recently constructed industrial plants similar to those proposed for this site. Rather than an industrial park, we offer instead a newly-designed multi-purpose Recreational–Ecological–Agricultural Park (REAP) & Nature Preserve which would maintain the integrity of the rural landscape, connect the densely-populated neighborhoods to the mangrove shoreline, and open nature’s treasure chest to urban Miami and the wider public.

Development Strategy of Urban Cultural Scene to Promote the Upgrading of Regional Cultural Consumption in Shaanxi

Regional cultural patterns and characteristics play a positive role in economic and social development.By planning and constructing cultural amenities and creating cultural scenes,the spatial quality and quality of life in a region can be enhanced,facilitating the expansion of cultural consumption.Shaanxi,with its rich historical and cultural resources,positions the capital city of Xi’an as a“world historical city”,boasting a vast number of cultural amenities represented by“cultural facilities”,“cultural activities”,“cultural experiences”,and“cultural services”.The development of urban cultural scene,with the aim of promoting the upgrading of regional cultural consumption in Shaanxi,requires comprehensive planning and a multifaceted approach,particularly in integrating provincial cultural scenes,clarifying the positioning of cultural scenes,innovating cultural scene experience projects,creating cultural scene intellectual property(IP),and empowering cultural scenes through the application of science and technology.

Spatio-temporal Pattern Characteristics of Relationship Between Urbanization and Economic Development at County Level in China

The relationship between China’s urbanization and economic development(RCUED) is an important concern nationwide. As important actors in regional strategy and policy, county-level regions have played an increasingly significant role in the development of China’s social economy. However, the existing research on the RCUED lacks the fine depiction of the county-level administrative units.Using 2000 and 2010 census data and the statistical analysis method, we uncovered the evolution characteristics of China’s urbanization and economic development and conducted a quantitative identification for the RCUED with improved methods using the quadrant map approach. In addition, we investigated the spatial correlation effect of the RCUED using the spatial autocorrelation analysis method. The results were as follows: 1) In general, a high degree of matching exists between China’s urbanization and economic development at the county level at the significance level of 0.01. The correlation coefficients between China’s urbanization and economic development in2000 and 2010 were 0.608 and 0.603, respectively. 2) A significant regional difference exists in the RCUED at the county level. Based on a comparative analysis of 2276 county units in China in the two years, we found that county units can be categorized as under-urbanized, basic coordination and over-urbanized in various areas. No situation was observed where urbanization seriously lagged behind the economic development level, so the levels of urbanization and economic development appear to be basically coordinated,and the coordination state may be gradually optimized over time. 3) Over time, the spatial dependency of the RCUED has weakened and the spatial heterogeneity has increased. Northeast China has always been an area characterized by over-urbanization. The number of county units classified as under-urbanized has begun to decline in eastern coastal urban agglomeration areas, while counties rich in resources have transformed from having point-shaped over-urbanization to plane-shaped under-urbanization along the northern border,and the number of over-urbanized county units has increased in the middle reaches of the Yangtze River. 4)’Lag-lag’ type and ’advance-advance’ type accounted for 68% of all counties in China, and these counties were shown to have obvious spatial differentiation characteristics.

Evaluation of coordinated development of regional resources and economy around Shandong Peninsula urban agglomerations

Promoting coordinated development of resources and environment is an important aspect of building a harmonious society and ecologically sustainable civilization. Here we provide scientific basis to promote the development of ecologically sensitive civilization, via a mathematical statistics method that calculates the degree of coordinated development. This model is of great practical and social significance, providing strength to research around coordinated development of resources and economy. Based on evaluation of characteristics of the present resource environment and economic development of Shandong Peninsula city group, a coordinated measure of resource environment and economic development was calculated. Overall, the highest coordination measurement was found for Weihai, followed by Yantai, Qingdao, Ji'nan, Weifang, Rizhao, Zibo and Dongying. According to evaluation results of coordination measures for each city, we put forward suggestions for sustainable development of Shandong Peninsula region.

Revisiting the Relationship Between Urbanization and Economic Development in China Since the Reform and Opening-up

The relationship between urbanization and economic development has become a hot topic in the scientific community due to its great practical significance,and economic and social value.However,this relationship continues to change dynamically.In the new stage of urbanization,it is urgent to reveal the causal relationship quantitatively and diagnose the future direction systematically.Based on this,this paper calculates the contribution rate of China’s urbanization to economic development from 1978 to 2019 and uses the panel data cointegration test method to explore the causal relationship between urbanization and economic development in China.The study has three principal results.First,the contribution rate of urbanization to economic growth has maintained the overall growth trend from1978 to 2019,but the growth rate of urbanization’s contribution to economic growth has been relatively low since 2012.It is an important reason that the real estate sector has moved into a new stage of transformation.Second,the cointegration test shows that economic development is a significant factor in advancing urbanization and the urbanization is the product of economic development.Urbanization has a positive feedback effect on economic development,but this effect does not pass the 5%significance level test.The impulse response function shows that the impact of urbanization on economic development is relatively small and stable,indicating that it is limited that the boost of economic development by land-centered urbanization.Third,China’s urbanization and economic development have both shown rapid growth for some time,but their relationship is still the low level of coordination,which has also led to a downward trend in the contribution of new-type,people-oriented urbanization to economic growth in recent years.In the future,China’s urbanization and economy need to maintain relatively medium-low speed growth in the medium-long term,and we should boost the coordinated development of urbanization and economy from low level to high level.

Research on the hierarchical structure of the metropolitan system and economic development of the provincial capital urban circle in Shandong

Regional development is the trend for future urbanization,and the urban circle is a highly efficient economic spatial pattern of regional development.This study selects statistical data of urban area population,GDP,and the output value of tertiary industry for seven cities in China- Jinan,Zibo,Tai'an,Laiwu,Dezhou,Liaocheng,and Binzhou- in the Shandong provincial capital urban circle from 2005 to 2009.It uses the principles and Zipf model,rank-size rule,and Lotka logarithmic model to analyze and study the hierarchical structure of the metropolitan system and economic development of the Shandong provincial capital urban circle.Based on the above research,this paper provides references for decisionmaking on enhancement of the metropolitan system structure,improvement in core city primacy index,the optimal adjustment of industrial structure and the optimal allocation of essential resources.

Correlation Between Economic Development Level and Landscape Pattern in Beijing Peri-urban Areas

With the rapid changes of demographic and socio-economic structure, various ecological and environmental problems have emerged in peri-urban areas. Studies on the correlation between socio-economic development and eco-environmental preservation are inadequate. This paper analyzes the landscape pattern of peri-urban areas to address this issue. First, it studies the differentiation of economic development levels in Beijing peri-urban areas. Then, it explores the correlation between economic development level of each town and its landscape pattern using Pearson Correlation and grade difference indices. Furthermore, it summarizes the problems within current landscape pattern. Three conclusions are drawn from the analysis: (1) on the whole, the economic de- velopment level in Beijing peri-urban areas basically matches with landscape pattern; (2) landscape contagion degree decreases with the growth of economic development level in as much as 30% of Beijing peri-urban areas. This is an irrational phenomenon accord- ing to our judgment; (3) landscape fragmentation grades in more than half of the towns are higher than their economic development grades, suggesting that attention should be paid to excessive fragmentation of land use.

Development Mechanism of Urban System in Rapidly Changing Period in China

The purpose of this research is to investigate the socio-economic development mechanism of China’s urban system in terms of spatial structure and its change. Totally 246 cities from 340 designated cities in 1985, and 488 from 640 designated cities in 1995 are selected as sample cities. And 22 attributes concerning urban features are analyzed to clarify the socio-economic characteristics and their changes in the urban system. Finally, the primary development factors are verified with the relationship of spatial structure and socio-economic characteristics. In conclusion, the socio-economic changes occurred more extremely than spatial structure changes. Furthermore, foreign investment be- came a major power for the development of China’s urban system in the period of 1985–1995.

Cooperative Game Among Cities in Urban Agglomerations and Economical Sustainable Development

This paper analyses redounded profits of cooperation and non-cooperation among cities in urban agglomerations based on game theory. It discusses the problems of economical development among cities with feeble cooperation, and deduces the conclusion that only cooperation of cities produces the maximum profits and realizes Pareto efficiency for cities and urban agglomerations. The paper states that cooperation is the cornerstone of economic sustainable development in urban agglomerations in profits produced by cooperation among cities. Some suggestions to accelerate cooperation among cities are proposed.

Empirical Study on the Relationship between Economic Development and Urban Construction Land in China: Based on the Panel Data of Provinces

The panel data of 31 provinces,cities and autonomous regions was used in order to test the relationship between economic development and urban land. The result showed that the sequences of economic development and urban land were in accordance with first order integration. Secondly,there was cointegration between economic development and urban land and the cointegration equation illustrated that 10% of increase in GDP per capita would drive 4. 94% of expansion in city construction land. Thirdly,according to error correction model,economic development is the Granger cause of urban land expansion in the long term while the reverse relationship was not proved. In short-term,economic development and urban land expansion were Granger causes of each other. The long-term equilibrium can only regulate the short-term imbalance of urban land,arriving at 33. 83%. Therefore,the government should formulate related policies to encourage real estate developers and enterprises to increase land utilization efficiency,strictly control the increase of urban land and regulate short-term imbalance.

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.

Research on Urban Agricultural Scientific Development Path of the Construction of Central Economic Region

The significance of developing characteristic agriculture in Central Economic Zone was elaborated from four aspects of three modernizations coordinated development,guaranteeing city supply of agricultural products,creating more jobs for farmers,making agriculture more significant. The existing problems in urban agriculture development were analyzed,such as understanding deviation,extensive development,market confusion,short industrial chain,low degree of specialization,harsh environment. Several corresponding countermeasures were put forward,including giving full play to the role of government's macro-control; perfecting compensation mechanism of urban agriculture,developing characteristic agriculture,promoting deep processing of agricultural products; advancing scientific innovation,improving production efficiency;operating sustainable ecological agricultural development road; relying on traffic advantage,promoting industrialization operation and urban agricultural logistics development.

高等教育规模、城镇化与区域经济增长机制研究——基于省级面板数据的证据

高等教育规模是经济持续增长的重要因素,城镇化是否在高等教育规模对区域经济增长的影响中发挥了重要中介效应,需要进一步研究。为此,可以基于2004一2020年国家统计局省级面板数据,分析高等教育规模与区域经济增长的关系,辨析城镇化在两者关系中的作用,进而探究高等教育规模、城镇化对区域经济增长的影响机理。研究结果表明:高等教育规模促进区域经济增长具有直接作用;城镇化对区域经济增长具有正向驱动作用;城镇化在高等教育规模促进区域经济增长过程中发挥了中介效应。这也证明了“高等教育规模一城镇化一区域经济增长”机制的存在。为有效利用该机制,建议适度扩大高等教育规模,加快培养高层次创新人才,因地制宜加快新型城镇化建设,推动城镇产业结构升级,建设现代化产业体系,促进区域经济快速健康发展。

中国城市群的发展测度:基于19个主要城市群

中国城市群研究主要基于地理学的局部视角,而对经济社会发展的整体性考量不足,对中国城市群整体发展规律的把握也有所欠缺。基于对中国19个主要城市群经济社会发展指标的分析,从要素集聚度、发展活跃度与可持续性三方面总结中国城市群的整体发展状况,并利用熵权TOPSIS、Dagum基尼系数对各城市群的综合发展状况进行评价与分解。从总体上看,主要城市群在国民经济发展中占有绝对主体地位,但经济带动作用有所下降;从城市群之间的差异看,主要城市群的发展差异始终凸显,优化提升类城市群的发展水平远高于发展壮大类与培育发展类城市群,发展壮大类与培育发展类城市群间的差距相对较小;从城市群内部的差异看,主要城市群内部的发展水平差异很大,且城市群内中心城市的极化作用有所增强。

省直管县改革能够促进共同富裕吗?——基于双重差分模型的实证分析

省直管县改革被视为发展县域经济、缩小城乡差距的重要举措,但已有研究对其能否实现缩小“三大”差距和推进公共服务均等化等共同富裕的主要政策目标仍存在争议。对此,以浙江省“省直管县”改革1997-2017年的面板数据为样本,运用双重差分法重新审视省直管县改革对实现共同富裕主要政策目标的整体效果。研究发现:省直管县试点和全面实施两个阶段对共同富裕均具有正向效应,且随着时间的推进呈现出逐年上升趋势。进一步分析发现,试点和全面实施阶段对共同富裕的正向效应存在区域差异,“省直管县试点”对共同富裕的影响具有“弱者变强、强者愈强”特征,而“省直管县全面实施”对共同富裕的影响则呈现出“抑强扶弱、协同发展”的特性。这些研究发现对优化省管县制度、探讨实现共同富裕的政策创新路径具有重要意义。
