Gap between Urban and Rural Economic Development in Less Developed Areas——A Case of Northern Jiangsu Area,China

Taking northern Jiangsu area as an example,economic disparity between urban and rural areas is described according to the data in 2000-2009 Jiangsu Statistical Yearbook.Result shows that there are significant differences in the rural and urban economic development in less developed areas,which are mainly reflected in the differences in per capita income,living standard,and Engel coefficient.Reasons for urban and rural economic disparity in less developed areas are analyzed.The asymmetry and immobility of rural and urban resources have objectively caused the income gap between urban and rural residents;urban industrial development,which is faster than agricultural development,has widened the income gap between urban and rural residents;and the differences in comparative labor productivity in rural and urban areas have enlarged their income gap.Countermeasures to minimize the urban and rural economic development gap are put forward,such as deepening the reform,realizing the free flow of economic resources between urban and rural areas,developing rural areas through urban development,exerting the function of urban areas in the coordinated development of urban and rural areas,paying attention to the agriculture and rural areas,and improving the comparative labor productivity of agriculture.

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.

Mutual Conversion of Land Use between Urban and Rural Area in the Process of Urbanization: A Case Study of Shandong Province

Urbanization is one of the driving forces for the land use change in type and structure, and its prominent effect is to convert rural land to urban land. This paper takes Shan-dong Province as an example to analyze the current situation of the mutual conversion between the urban and rural areas from the aspects of the structure of land use, the decreasing tendency of the cultivated land, the changes of land use in urban and rural residential areas. It points out that cultivated land is converted to residential area land, industrial and/or mining area land. The relationship between the urban area land and the cultivated land is more direct; meanwhile, the changes of rural residential area lag behind obviously. The decrease of the cultivated land and the decline of soil quality will be the two difficult problems in the process of urbanization.

Look from the empty nester problem of urban and rural dual structure of society

More and more empty nest has become a social problem that couldn＇t ignore. The problem of empty nester is the essence of urban and rural dual structure social changing. The emergence of empty-nesters is a serious problem in China＇s social development process, with the aging of the population increasing, urban-rural divide more and more obvious. The condition of the human society has gradually formed the rural and the division of labor and the dual structure of the city. This paper expounds the connotation, significance and characteristics of empty nest elderly, analyzes on the problems existing in current urban and rural society and the problem of empty nest elderly in the new situation puts forward the suggestions and countermeasures.

Suburbanization and Subcentering of Population in Beijing Metropolitan Area:A Nonparametric Analysis

This study focuses on the suburbanization and subcentering of population and examines the nature of spatial restructuring in terms of the population distribution in the Beijing metropolitan area.Instead of the classic density function approach,we employ the nonparametric analysis to characterize the spatial pattern of population densities in the Beijing metropolitan area and identify the suburban subcenters.Our findings suggest that the population has spread with rapid urban growth in the Beijing metropolitan area,and the compact urban form has been replaced by a more dispersed polycentric spatial distribution.However,compared with the decentralization of western cities,the spatial extent of the decentralization of population in the Beijing metropolitan area is quite limited.The rapid growth of population in the near suburbs has expedited the sprawl of the central city,with a larger central agglomeration of population dominating the metropolitan area.In this sense,the spatial pattern of the Beijing metropolitan area is still characterized by the continuous compactness.However,our findings do provide the evidence that the city has been turning to a polycentric structure.We find significant population subcenters have emerged in the suburbs of Beijing since the 1980s.But the polycentricity emerged in the Beijing metropolitan area is very different by nature from that observed in Western cities.The subcenters emerged are adherent to the development scheme planned for the city,so it can be referred to as the so called 'planned polycentricity'.

Empirical Study on Effects of Different Types of Urbanization on Consumption Structure of Rural Residents in China

In the process of urbanization,there are problems of decline in rural population,shrinkage of rural area,and constant increase in the per-capita net income of rural residents. These problems have brought about new characteristics and changes to the consumption structure of rural residents. This paper divided the urbanization into population urbanization,industrial urbanization and land urbanization. Using the panel data of 31 provinces in 2004-2013,it established the dynamic panel model and analyzed the effects of different types of urbanization on the consumption structure of rural residents. Results indicated that population urbanization exerts a negative effect on development-oriented consumption expenditure of rural residents,while it exerts a positive effect on enjoyment consumption expenditure; the industrial urbanization exerts a negative effect on the consumption expenditure of rural residents,while it exerts a positive effect on clothing and transportation communication consumption of rural residents; land urbanization exerts a negative effect on medical care expenditure in enjoyment consumption of rural residents. In view of these problems,it came up with recommendations,including stimulating the development of rural consumer market,liberating the consumption potentiality of rural areas,making clear emphasis points of different types of urbanization,avoiding promoting the urbanization in a blind manner,and adjusting the development of different types of urbanization on the basis of the consumption demands of rural residents.

The Influence of the Urban-Rural Income Disparity on the Industrial Structure—Taking the Yangtze River Delta Region as an Example

In this paper, the effect of the mediation effect is mainly used to test and analyze the regression model, and most scholars have studied the impact of the modernization of the industrial structure on the income gap. However, this paper is from another perspective, based on the social background of high-quality development, the main study is the impact mechanism of urban and rural income gap on the industrial structure, taking the Yangtze River Delta as the main research object, and specifically selecting 22 central cities in the Yangtze River Delta region, which is also one of the highlights of this study. The regression model is constructed by using the intermediary effect, and the four intermediary variables of fiscal expenditure (M1), fixed asset investment (M2), number of patent applications (M3), and total import and export (M4) are selected, which represent the role of the government, fixed asset investment, scientific and technological level and opening-up level, and study and analyze the inherent influence mechanism between each variable. Before doing specific research, I consulted the papers and literature of many other outstanding scholars, among which Cheng Yuhong and Cheng Chi’s “The Influence Mechanism of industrial structure of urban and rural income gap” [1] has great reference value for this paper. According to the research results, under the background of high-quality development in the Yangtze River Delta region, the expansion of the income gap between urban and rural areas will inhibit the upgrading of the industrial structure, so it is necessary to focus on building a new type of urbanization, accelerating the construction of an urban innovation system, optimizing the rural employment structure to narrow the income gap between urban and rural areas, and providing impetus for the continuous upgrading of the industrial structure.

再分配视域下河北省人口老龄化与城乡收入不平等的关系分析

再分配作为调节收入分配的重要工具,在实现共同富裕目标中发挥着重要作用。河北省作为人口大省,日益加重的人口老龄化对经济社会发展、城乡收入等产生了重要影响。研究发现:一方面,河北省人口老龄化拉大了城乡收入差距,加剧了城乡收入不平等,尤其是在二线城市和大规模城市中,人口老龄化引致的城乡收入不平等效应更加明显;另一方面,经济增长作为“做大蛋糕”和“分好蛋糕”的原动力,能够有效“对冲”人口老龄化对城乡收入分配不公的负面影响,而人口老龄化倒逼技术进步又在一定程度上加剧了城乡收入不平等。因此,河北省不仅要做大“财富蛋糕”,更要使全体社会成员共享“经济蛋糕”,以此加速推进共同富裕进程。

人口特征对中国经济社会需水影响及峰值预测

人口规模结构是决定水资源需求的关键因子,在人口总量负增长的重大变化背景下,中国经济社会需水如何演变直接关系到水资源管理宏观决策。本文通过分析中国人口城乡结构、年龄结构对经济社会需水的影响规律,构建了基于人口特征的需水变化曲线,并在此基础上预测了经济社会需水演变态势及峰值时点。研究结果表明:中国经济社会需水峰值可能出现在2042年,达峰规模约为7300亿m^(3);2050年之前,城镇地区需水总量将会持续增加,农村地区需水峰值将于2030年左右出现。经济社会需水规模是决定区域用水特征的边界条件,研究认为在中国经济社会需水还未到达拐点、国际贸易环境动荡加剧的背景下,未来中国供水保障还应该保持一定的弹性和韧性。

人口变化背景下我国城乡义务教育资源需求预测与规划

人口规模和结构的变化直接影响着教育资源供需形势的变化。准确把握学龄人口的变动状况,是合理规划城乡义务教育资源的重要前提。基于第七次人口普查数据源,运用CPPS人口预测工具系统,对2023—2035年我国城乡义务教育在校生数量进行预测发现,义务教育在校生数总体上呈现下降趋势,小学阶段在校生数的下降规模呈现出城市>县镇>农村的趋势,初中阶段在校生数下降规模则呈现县镇>城市>农村的趋势。在义务教育学龄人口变动影响下,2023—2035年义务教育资源需求变化主要集中在师资、教育经费以及校舍上。师资上,义务教育阶段师资需求总体呈下降的趋势,城市、县镇、农村小学阶段的师资需求将分别下降87.60、85.46、60.44万人,城市、县镇、农村初中阶段的师资需求将分别下降68.77、83.28、22.10万人;教育经费上,小学、初中阶段教育经费需求的涨幅分别为15.41%和5.96%;校舍上,城市、县镇小学仍有一定的缺口,农村小学、县镇和农村初中则将出现大量校舍闲置状况。基于此,可通过构建城乡义务教育资源跨周期调节机制、促进城乡教师队伍协调高质量发展、健全义务教育经费保障机制、分类科学合理规划利用闲置校舍等策略,应对人口变化给我国城乡义务教育带来的资源需求变动。

数字新质生产力对城乡高质量融合的影响与机制

数字新质生产力能够深刻改变城市与农村生产及生活方式,对城乡高质量融合具有重要意义。基于2009—2022年我国30个省份(未含香港地区、澳门地区、台湾地区及西藏地区)面板数据,利用固定效应模型、中介效应模型及门限效应模型,实证检验数字新质生产力对城乡高质量融合的影响和作用机制。研究发现,数字新质生产力能够显著促进城乡高质量融合、产业结构升级、公共服务均等化,特别是资源要素配置优化在数字新质生产力对城乡高质量融合的影响中起中介作用。数字新质生产力对城乡高质量融合的促进作用具有边际效应递增的非线性特征,产业结构升级、资源要素配置优化、公共服务均等化对这种非线性影响具有强化作用。数字新质生产力对城乡高质量融合的影响具有地区异质性,从线性影响看,在东部地区最强,在中部地区其次,在西部地区最弱;从非线性影响看,数字新质生产力的影响在东部和西部地区存在单一门限效应,在中部地区存在双重门限效应。为促进城乡高质量融合,应积极推动生产要素数字化转型,加快数字新质生产力形成;驱动产业结构升级,为城乡高质量融合提供动力;畅通资源要素流动渠道,优化资源要素配置;加强公共服务配套设施建设,助力公共服务均等化;结合地区特点,因地制宜培育数字新质生产力。

新冠疫情对城镇人口流网络结构韧性的影响——基于南京都市圈同城化片区的实证研究

新冠疫情(COVID-19)对城镇(乡)间人口的有序流动产生潜在冲击。文章以南京都市圈同城化片区的乡镇街道为对象,基于2019和2021年各半个月的手机信令大数据,运用复杂网络技术揭示疫情前后的人口流动网络格局;构建韧性评价指标,采用顺序性攻击高值节点、一次性攻击跨界节点2种方式,模拟测试网络结构韧性的变化。结果表明:1)伴随常住人口的增多,疫情后的人群跨城镇出行依然活跃,但疫情瓦解了大量远程、长程联系;2)疫情冲击增加了休闲流和就业流网络的波动程度和中转次数;3)高中心性的跨界地区是维持全局网络结构韧性的关键性节点地区。研究表明时空大数据在城镇(乡)网络结构韧性评价及风险全流程治理方面具有较好应用前景。

湘鄂渝黔革命老区县域数字电商物流协同城乡融合发展研究

革命老区作为特殊类型地区仍然是目前城乡区域协调发展中的短板地区,利用湘鄂渝黔革命老区人口、经济统计数据,结合地理空间分析工具,进行人口与经济分布不均衡分析,人口与经济地理集中度分析,人口与经济空间分布一致性分析,揭示湘鄂渝黔四省(市)交界、武陵山区地理特征、少数民族分散聚居和以传统农业及三产为主的经济结构,是城镇化水平较低、城乡二元的客观原因,而人口分布与经济格局亦存在发展不平衡不充分的突出问题,区域协调协同发展还有差距。为实现湘鄂渝黔革命老区高质量发展探索有效途径,论证数字经济下优先发展电商物流将有助于湘鄂渝黔革命老区乡村振兴及新型城镇化建设,利用合理的评价指标进行湘鄂渝黔革命老区县域对象各自及不同分类区域整体之间城镇化、物流供应链和农村电商相关指数比较,利用①耦合协调度模型进行县域城镇化、②物流供应链和③农村电商三元系统耦合协调关系分析,结合研究提出了推进区域高质量发展的相关建议。

乡城流动老年人能动适应的运作机制与发展型城乡结构的形塑

运用“结构—行动”二重性的分析框架,从主位角度分析了乡城流动老年人的社会适应性,结果显示:乡城流动老年人对城市社会适应问题的应对会通过对经济结构中的机会获取、关系结构中的规则调适与意义结构中的空间进退来予以能动调适,其能动适应的实现离不开多重结构的支撑;发展型城乡结构与城乡融合的实现也离不开个体家庭的能动实践,后者主要包含家庭经济的合作主义、家庭结构的弹性与家庭伦理的韧性调适几个层面。在结构与行动的能动互塑下,乡城流动老年人的社会适应与发展型城乡结构之间实现了有机的嵌合,因而为保障城乡融合发展的渐进式韧性实现,应在政策上尊重乡城流动老年人的自主意愿与为他们在城乡间有主体性的两栖穿梭提供保护。

丝绸之路经济带核心区城乡融合发展的影响因素研究

作为“一带一路”建设的核心区、枢纽地带,新疆在推动城乡融合与对外开放方面有着至关重要的意义,同时对于促进当地经济社会发展具有深远影响。城乡融合是新时代下中国发展的重要战略方向,旨在实现城乡资源要素的共享和优势互补,城乡产业结构也逐渐向现代化、国际化的方向发展,实现城乡产业的互通和融合。本文测度并对地区层面面板实证检验城乡融合结果显示,目前新疆城乡融合水平较低但正稳步提升,地区差异较大且趋于缩小。对外开放稳健促进新疆城乡融合协调发展。

破解农业转移人口市民化困境新思路——与就业人口挂钩的“兑地法”探索

加快农业转移人口市民化,是推进新型城镇化战略、促进区域协调发展的重要举措。研究发现,农地私有化或同地同权仅对大城市近郊农民有利,无助于解决广大农村问题,资本下乡则未能提高农业生产效率,反而出现利用城乡建设用地增减挂钩套利、挤占农民补贴、基层组织异化、农民失地的困境。基于此,可考虑以就业人口为主的兑地法破解农业转移人口市民化困境新思路:一个城市的发展如果能够吸纳较多的就业人口,那么该人口在农村相应的农地、宅基地等,即挂钩到就业城市指标中,就业城市以此指标按比例获得工商业、住宅等建设用地指标。由于就业城市能够获得较多的土地出让收入,从中抽取少许资金即可安置相应的就业人口,安置完成后,该就业人口对应的农村农地、宅基地等实物可在原户籍地流转给留在当地居住且有集体身份的专业农户,发展50亩以下的小型家庭农场。该方法可以优化劳动力和土地的资源配置,提升生产效率和增加消费,且在社会过渡上也会较为平稳,相比农地私有化或同地同权与资本下乡,更切合国家需要。
