Influence of Transportation Accessibility on Urban-rural Income Disparity and Its Spatial Heterogeneity

Transportation accessibility has been treated as an important means of reducing the urban-rural income disparity.However,only a few studies have examined the effects of different types of transportation accessibility on urban-rural income disparity and their spatial heterogeneity.Based on data from 285 prefecture-level(and above)Chinese cities in 2000,2005,2010,2015,and 2020,this study uses spatial econometric models to examine how highway accessibility and railway accessibility influence the urban-rural income disparity and to identify their spatial heterogeneity.The result reveals that highway accessibility and railway accessibility have‘coreperiphery’ring-like circle structures.The urban-rural income disparity exhibits strong spatial clustering effects.Both highway accessibility and railway accessibility are negatively associated with urban-rural income disparity,and the former having a greater effect size.Moreover,there is a substitution effect between highway accessibility and railway accessibility in the whole sample.Furthermore,these associations differ in geographic regions.In the central region,highway accessibility is more important in reducing the urban-rural income disparity,but its effect is weakened with the increase of railway accessibility.In the western region,railway accessibility has a larger effect on narrowing the urban-rural income disparity,and this effect is strengthened by the increase of highway accessibility.We conclude that improving transportation accessibility is conducive to reducing the urban-rural income disparity but its effect is spatial heterogenetic.Highways and railways should be developed in a coordinated manner to promote an integrated transport network system.

The Evolution of Urban and Rural Construction Land Based on Spatial Econometrics:A Case Study of Bijie City

Based on the theory of spatial econometrics,we test and process the urban and rural construction land data during the base period of planning and late period of planning in Bijie City.And we conduct comparative analysis of the spatial pattern and evolution characteristics of urban and rural construction land in 41 towns of Bijie City before and after the planning.According to Getis-ord G i coefficient test results,the cold spot area of urban and rural construction land in northeast of Bijie City will gradually disappear,and the key point of hot spot area will be gradually transferred from the central region to the central and eastern regions.The results show that under the guidance of the overall land use planning in Bijie City,the urban and rural construction land will show strong spatial autocorrelation;agglomeration benefits and scale merit will appear clearly,in line with the actual situation of current development of Bijie City.

A new approach towards the sustainability of urban-rural integration:The development strategy for central villages in the Abbasiya District of Iraq using GIS techniques

The development of rural areas usually has a positive impact on the urban-rural integration. This study explores an innovative approach to stimulate rural development by proposing qualified villages as central villages that can provide basic urban services for their residents and residents of neighboring villages. This approach can contribute to overcoming the various problems that rural areas faced at the social, economic, and environmental levels. It seeks to achieve spatial sustainability of rural areas, representing a new approach by integrating urban development methods to revitalize rural villages. The study analyzed 15 villages belonging to Abbasiya District of AL Kufa City in the Najaf Governorate of Iraq. Based on the GIS techniques and the analysis of urban service indicators(village population, percentage of urban building materials used in villages, distance between village and health centers, distance between village and main roads, nature of economic activity, distance between village and educational institutions, distance between village and drinking water sources, number of communication towers, and distance between village and urban administrative center), this study proposed that Abu Gharb and Albu Ghraib can served as central villages in Abbasiya District in the future. This study establishes a new rural spatial structure to achieve rural sustainable development, improves the development status of rural areas, and provides a theoretical basis for the government and relevant institutions to use urban service indicators, achieving rural sustainable development and formulating relevant development policies in Abbasiya District.

Influencing Factors for Formation of Urban and Rural Spatial Structure in Metropolis Fringe Area——Taking Shuangliu County of Chengdu in China as a Case

With rapid urbanization process, the pace of urban sprawl has been quickened and most metropolises have ex-perienced expansions in leaps and bounds in suburbanization, which has greatly changed the urban and rural spatial struc-ture of the metropolis fringe area. In this paper, Shuangliu County is taken as a case, since it is a typical fringe area of Chengdu Metropolis. Based on Landsat TM images of Chengdu City and Shuangliu County obtained in 1985, 2000 and 2004, characteristics of urban and rural spatial structure in Shuangliu County were analyzed, such as core-periphery spa-tial structure and some obvious integration trends. Then the influencing factors for the formation of urban and rural spatial structure were identified, including some natural, social, economic and political factors. According to the discussion of this paper, Shuangliu County is undergoing a key transition and reform period. Its formation of urban and rural spatial structure was affected not only by such common factors as the location, natural background, industrial transition, migra-tion, etc., but also by some unique factors such as city planning and policy guidance, which played an important role in accelerating its uneven spatial structure. The understanding of the role of the influencing factors would be useful for car-rying out spatial management and development planning of metropolis fringe area.

Fiscal Expenditure and Income Gap between Urban and Rural Residents: An Empirical Study Based on Malmquist Index and Spatial Econometrics

Based on the analysis methods of non-parametric Malmquist index and spatial econometrics as well as the provincial panel data in 2007-2010, this paper estimates the efficiency of fiscal expenditure from local governments in china in terms of reducing the income gap between urban and rural residents for the first time and evaluates the spatial correlation and heterogeneity of this efficiency. The results have shown that the fiscal expenditure of most provinces is of low efficiency in reducing the income gap between urban and rural residents, and the expenditure efficiency of local governments is not relevant to their levels of economic development. Besides, the efficiency on reducing the urban-rural income gap between different regions of China has a tendency of convergence. But this is mainly reflected inside the regional economic belt. There is significant difference between the efficiency of each economic belt. The central region has the highest efficiency in a rising trend, the western region has the lowest efficiency in a downward trend, while the eastern region is relatively stable.

Study on Spatial Structure of Rural Tourism in Wuhan Urban Agglomerations

Spatial structure of rural tourism in the urban agglomerations of Wuhan was analyzed by comprehensively studying relevant documents about rural tourism,and reviewing previous researches on the concept and spatial structure of rural tourism.Through investigating rural tourist resources in the study area,resource advantages and characteristics of 9 cities were introduced,and the Gini Coefficient was taken to quantitatively analyze spatial patterns of its rural tourist villages,the obviously imbalanced concentration of these villages was pointed out.By measuring connectivity and accessibility of regional spaces in the study area,its traffic connectivity was proved moderate,and accessibility of each tourist village and town was fine.Then an optimized spatial structure was proposed for the rural tourism development in Wuhan Urban Agglomerations,that is,"one core,one belt and three districts".

SOME EMPIRICAL EXAMPLES OF CENTRAL PLACE MODEL IN CHINA'S RURAL AND URBAN STUDIES

At the beginning of the 1980s, the Central Place Theory(CPT) was introduced into China from the West. The authors of this article are the initiators of applying this model to China's urban and regional planning as well as to the allocation of commercial activities. Since the commodity economy has been developing in China for thousands of years,most of the areas in eastern plains and inland basins of the country show the spatial structure of typical central places scene. During some six years, the authors participatd in a lot of rural, urban and regional planning projects in which the spatial phenomena and relevant internal mechanism proved this medel and its deformation. This paper gives only a few examples of the application of CPT in China. 1. The distribution of rural markets: the empirical study is based mainly on the situation in Shengfang Town and its vicinal area, 2. The spatial combination of urban Systems; problems about city allocation in North China are emphasized, 3. Commercial centres in city and the networks: a crucial study on commercial distribution of the metropolis Beijing is done by using the central place model.

GIS- and RS-based Analysis of Suburban Landscape Layout in Haikou City

A Spatial Supply-Demand Imbalance Between Rural Primary and Secondary Schools in Shaanxi Province Based on Road Network Analysis

It is of great significance to optimize the spatial matching of basic education facilities in rural areas and promote the equalization of urban and rural basic public services and the overall revitalization of rural areas.Based on the theory of spatial accessibility and spatial balance of supply and demand,this paper constructs the evaluation system of rural basic education facilities and layout rationality.In this study,we took 42 primary and secondary schools and 2089 rural areas with concentrated population in six township areas of Hancheng City as the research subjects.We used ArcGIS network analysis,population coupling model,and other methods,from the administrative scale and rural population concentration area scale for evaluation.The accessibility of basic education facilities and its coupling relationship with the spatial distribution of student population describe the spatial and geographical pattern of basic education facilities in rural areas.The results show that the accessibility of rural administrative scale and the spatial balance of supply and demand of population concentration area scale are associated with great problems,the differences between towns are obvious,and the overall level of the best performing towns is still low.On the scale of population concentration area,the overall coupling degree is too low,the"dislocation"distribution of educational facilities and student population is obvious,and the matching degree of the student population and school in different towns is significantly different,showing a more obvious"core-periphery"spatial structure characteristics centered on the eastern and southeast regions.The terrain characteristics of rural areas in Shaanxi province are prominent,and the accessibility of the road network is particularly significant.Therefore,optimizing the construction of rural roads and optimizing school layout according to local conditions will become an important solution to promote the balanced allocation of basic education resources in Shaanxi province.

Urban Development Boundary Simulation Based on“Double Evaluation”and FLUS Model

The delimitation of urban development boundaries plays an important role in optimizing the nation land space.“Double evaluation”is one of the important means to study and predict the scale of new construction land in the future and to determine the spatial distribution of urban construction land.This study combines the“double evaluation”with the FLUS(Future Land-Use Simulation)model to study the delimitation of the urban development boundary of Yichang.The results show that:(1)the“double evaluation”method comprehensively considers the carrying capacity of the resource environmental bear and the suitability of urban development;(2)the FLUS model can better couple the“double evaluation”method for Land Use/Land Cover(LULC)suitability evaluation,Land Use/land Cover Change(LUCC)simulation and urban development boundary delineation,and the overall accuracy of the simulation reaches 96%;(3)according to the requirements of relevant national policies,this study divides the urban development boundary of the study area into concentrated construction areas,elastic development areas and special purpose areas.This function-based division can meet the requirements of urban flexible development,ecological protection and urban safety.This research combines the FLUS model,which is widely used in the simulation of LUCC,with the double evaluation method used in China’s new round of land and space planning to obtain the result of the urban development boundary.This result is consistent with the existing plan of the study area.

Research of Spatial Construction Strategy in Chinese New Rural Community

Through the field survey of traditional rural settlement,it has found that the typical spatial construction model shows the duality of matrix and landmark and they are in a relation of reciprocal causality.However,under the impact of urbanization and modernization,this spatial construction model is disappearing,and those natural villages are integrated and reconstructed at a high speed and in a large scale during the construction of new rural communities,leading to a lack of geographical construction system and a damage of ecological living environment.In the perspective of prototype theory,the duality feature should be combined with spatial construction model to guide the inheritance and application of spatial construction model of traditional rural settlements and seek for new spatial development approach for new rural communities based on the sustainable,alternative and transformation strategies.

Low Carbon Urban Design Concept Planning of Handan Eastern New District

Currently urban issues show a dramatically increasing rely on auto use,which seriously affects the sustainable development of the city and makes how to build low-carbon cities become one of the urgent problems to be solved in the process of urban development.Therefore,low-carbon cities have become principles for China’s next generation of growth and the research hot spot of urban traffic planning.By taking a look at the concepts such as Compact City,transit-oriented development(TOD)city and‘small block’zoning,the article combined the relationship between urban spatial layout patterns and traffic development mode to build a green,low-carbon and sustainable urban development model.Finally,taking the urban design of the new district in the east of Handan City as an example,this research applied the concepts and approaches to planning practice,hoping to provide reference for building low carbon cities.

Types, Distribution Characteristics, and Development Strategies of Rural Characteristic Industry in Xi’an Metropolitan Area

China’s urbanization development has entered the“second half”,which is at a critical stage of transition from the middle stages to the mature stage.The metropolitan area formed by the mega-city radiating the development of surrounding cities and counties is an important spatial carrier of urbanization.The rural characteristic industry is the main path to promote regional economic development and urban-rural integration in the metropolitan area.Exploring the development characteristics of rural characteristic industries in the metropolitan area has important theoretical and practical significance for promoting the effective connection between urban-rural integration and rural revitalization of the metropolitan area and improving the development quality of the metropolitan area.Take the Xi’an metropolitan area as an example and adopt kernel density analysis and other methods to reveal the spatial differentiation rules of rural characteristic industries.On this basis,the three-dimensional development strategy of“industry-spatial-institutional”for the development of the rural characteristic industry is proposed,to provide theoretical reference for the development of rural characteristic industry in metropolitan areas.

要素流动对城乡融合发展的影响机理与空间分异研究

城乡要素双向自由流动有利于提高要素配置效率和优化城乡关系,促进城乡融合发展。现有关于要素流动对城乡融合发展的研究主要围绕传统生产要素对城乡融合发展的研究展开讨论,鲜有文献将数据这一新型生产要素纳入城乡要素流动范围并探索其对城乡融合发展的影响机理。基于2010—2021年中国31个省份的面板数据,在测算要素流动、城乡融合发展水平的基础上,构建双向固定效应模型、地理加权回归模型和中介效应模型实证检验要素流动对城乡融合发展的影响效应及作用机制。研究发现:第一,全国要素流动总指数呈现出小幅度增长的态势,位于均值之上的地区中64%是城乡融合发展试验区,说明城乡融合发展政策实施具有重要的引导作用;第二,要素流动显著促进城乡融合发展,这一结论在引入城乡之间距离作为工具变量进行内生性检验、采用删除4个直辖市和缩短时间窗口的方法进行稳健性检验之后仍然成立;第三,空间异质性分析中,劳动力、土地和数据要素始终表现出促进城乡融合发展的作用,随着时间的推移,土地要素对不同地区城乡融合发展影响程度逐渐增强、影响范围逐步扩大,技术要素对城乡融合发展的促进逐渐凸现,由华东和华南地区向东北和西南地区转移;第四,在要素流动影响城乡融合发展的过程中,电商销售是要素流动影响城乡融合发展的重要途径,农业机械化和产业结构变迁并未发挥出中介变量的作用,不同于已有的研究结果。因此,今后持续深化城乡融合发展的内涵与外延、拓展深度与广度;始终以习近平新时代中国特色社会主义思想为指导,运用科学的世界观和方法论,坚持整体推进与试点示范相统一的指导原则,推广实践中形成的典型经验。研究结论为城乡要素双向合理流动的机制建立、城乡融合发展体制机制的健全提供了理论和经验上的参考。

如何优化乡村小规模学校布局

乡村小规模学校布局优化是城乡教育一体化发展的重点和难点,更是确保乡村儿童接受公平优质教育的重要基础。但现实中,小规模学校布局仍存在诸多问题:布局分散程度高;决策中缺少科学的程序和技术;布局规划中学校教育资源不足、弱势学生入学机会不均等;校际空间隔离,跨校资源共享难以稳定持续等。因此,应进一步明确小规模学校布局优化的逻辑理路:以教育规划理论引领布局优化的教育功能发挥;以“公平、效率、质量”框架重构布局规划目标;以“集中+分散”布局结构为乡村振兴奠定教育服务基础;以“入学可达性提升”促进乡村儿童入学机会均等;以资源均衡配置促进城乡学校一体化发展。同时,围绕“空间可达、服务范围、学校规模、校际发展优质均衡程度、能否促进学校传承乡土文化”等维度因地制宜设置学校布局标准,并提供支持性策略,主要包括:综合区位因素,构建小规模学校布局与乡村振兴规划融合系统;以参与式GIS技术为基础,优化学校布局规划程序;强化各级政府责任,妥善处理好布局规划中的伴生问题;共享教育资源,促进小规模学校与县镇学校一体化发展。

城乡建设用地增减挂钩政策与城乡收入差距

在空间均衡视角下,建立理论模型分析城乡建设用地增减挂钩政策对城乡收入差距的影响,并通过实证分析进行政策评估的结果表明:增减挂钩政策能够提高城乡居民人均收入,但是对城市居民人均收入提高幅度更多,从而加大城乡收入差距。如果配套实施农村生产率提升的增减挂钩政策,在提高城乡居民人均收入的同时,这种综合性改革能够促使农村人均收入提高幅度更大,进而缩小城乡收入差距。随后,基于2000—2016年省级面板数据,采用逐期双重差分法与合成控制法分别评估城乡建设用地增减挂钩政策与配套实施农村生产率提升的增减挂钩政策对城乡收入差距影响的实证结果发现:自2006年实施增减挂钩政策后,增减挂钩试点省份的城乡收入差距均值提升0.125,达到2.820;自2008年实施配套农村生产率提升的增减挂钩政策后,重庆市的城乡收入差距均值下降0.261,达到3.043。基于此,在城乡融合背景下,我们应建立健全城乡统一建设用地市场制度。

基于中国省级面板数据对数字乡村建设促进城乡共同富裕的研究

数字乡村建设是实现城乡共同富裕的重要实践路径。本研究基于2011—2020年我国31个省份的面板数据,构建数字乡村评价指标体系,实证探究了数字乡村建设对城乡共同富裕的影响。研究表明:(1)数字乡村建设有利于收敛城乡收入差距,进而促进共同富裕。(2)异质性结果表明数字乡村建设对东部地区的促进作用更强。(3)机制分析表明非农就业是数字乡村建设促进共同富裕的重要路径。(4)数字乡村建设水平对共同富裕的作用存在空间溢出效应。

城市外围地区农村物流设施空间分布演变及影响因素--以广州市为例

城市外围地区农村物流设施是保障城乡物资双向流通和农村产业发展的重要支撑。以广东省广州市为例,综合使用多源空间数据和空间回归模型等分析方法,探索城市外围地区农村物流设施空间分布演变特征及影响因素。在空间分布演变方面,城市外围地区农村物流设施从单核转向多核,具有圈层化、等级化特征,与广州市空间发展方向和空间格局相一致,最外围地区物流设施建设短板突出;受村级设施分布变化影响,物流设施集聚性呈现“增强—减弱—增强”的波动。影响因素方面,人口因素、交通因素和工业因素对物流设施分布有显著正向影响,农业因素对其有显著负向影响,区位因素对其无明显影响。研究结果能够丰富对农村物流设施分布演变规律的认识,为城市尺度的农村物流设施的布局优化和支撑要素的建设等提供参考。
