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.

Study of Urban and Rural Construction Land Change Based on Small Scale in Dafang

This paper is to examine the urban and rural construction land data of Dafang between basic year and final year based on country scale and spatial econometrics,and analyze its spatial pattern and change feature. According to the results,the construction lands in all the villages of Dafang County showed strong spatial autocorrelation and significant spatial cluster. After the analysis of local Moran's I,the construction lands in 381 villages of 36 counties presented strong activity. The original small-scale villages were gradually enlarging,which will not only gradually benefit local development,but also be in accordance with the strategy of " one city,one district,eight parks".

Discussion on Mode of Key Link in Increase and Decrease Connection of Urban and Rural Construction Land

With the methods of qualitative analysis, induction and deduction, modes of key links in increase and decrease connection of urban and rural construction land are proposed in view of the involved three key links, namely reclamation of rural construction land, fund raising and management of connection turnover index, based on the comprehensive analysis of political connotation in increase and decrease of urban and rural construction land. The modes include "village relocation and combination", "hollow village" reconstruction, high-rise stereo, village relocation in the mountain and related capital raising and turnover index management and the applicable regions of various modes are analyzed and studied. The research result provides reference for the reasonable operation of increase and decrease link of urban and rural construction land.

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.

Study on the Construction of China's Unified Urban-rural Construction Land Market

State-owned urban construction land market in China has evolved and been improved gradually, but use system of rural collective construction land has lagged far behind, so the urban-rural construction land market in China has been split with a result that use effi ciency of land resources is poor and collective land property rights of peasants are damaged. On the basis of analyzing problems of the current construction land market and also the causes, modern land property theory and institutional change of neoinstitutional economics are applied to study dynamical mechanism and development path of the construction land market, to construct the unifi ed construction land market system of China, and to propose corresponding guarantee policies, so as to achieve the effective allocation of construction land and maximization of social welfare.

Model and Strategy of Urban and Rural Construction Land Market Integration

At present,one of the important contents of China s rural land system reform is to build a unified construction land market in urban and rural areas.The unified construction land market in urban and rural areas will produce higher economic and social benefits.It is imperative to promote the integration of urban and rural construction land market to improve the income of farmers,invigorate the stock of rural collective construction land and improve the efficiency of land use.This paper analyzes the current situation of urban and rural construction land market,the two models and typical cases of urban and rural construction land market integration,the restrictive factors and practical difficulties of urban and rural construction land market integration,and puts forward some suggestions and measures.This provides a theoretical basis for accelerating the integration of urban and rural construction land market,and hopes to provide a certain reference for the integration of urban and rural construction land market.

Spatio-temporal analysis of land-use conversion in the eastern coastal China during 1996-2005

Based on the acquaintance of the regional background of urban-rural transformational development and investigations on the spot,this paper discusses the holistic situation, dominant factors and mechanism of arable land loss and land for construction occupation in the coastal area of China over the last decade,with the aid of GIS technology.Conclusions of the research are summarized as follows：（1）the arable land had been continuously decreasing from 1996 to 2005,with a loss of 1,708,700 hm^2 and an average decrement of 170,900 hm^2 per year;（2）land for construction increased 1,373,700 hm^2 ,with an average increment of 153,200 hm^2 per year;（3）total area of encroachment on arable land for construction between 1996 and 2005 was 1,053,100 hm^2 ,accounting for 34.03%of the arable land loss in the same period,the percentages of which used for industrial land（INL）,transportation land（TRL）,rural construction land（RUL）and town construction land（TOL）are 45.03%,15.8%,15.47%and 11.5%,respectively;and（4）the fluctuation of the increase of construction land and encroachment on arable land in the area were deeply influenced by the nation＇s macroscopic land-use policies and development level of regional economy.The growth of population and advancement of technology promoted the rapid industrialization, construction of transportation infrastructures,rural urbanization and expansion of rural settlements in the eastern coastal area,and therefore were the primary driving forces of land-use conversion.

The Decoupling Relationship between the Expansion of Urban Construction Land and Economic Growth in Jilin Province

In order to explore the relationship between urban construction land and economic development, this paper uses a decoupling model to analyze the decoupling relationship between expansion of urban construction land and economic growth in Jilin Province. The results show that from 2000 to 2015, the decoupling of urban construction land expansion and economic growth in Jilin province tended to be reasonable. The paper divides urban decoupling into three categories. The first type consists of ideal cities, including Liaoyuan and Baishan. The second type includes basic ideal cities like Changchun, Tonghua, Songyuan, Baicheng, and Yanbian. The third type consists of non-ideal cities, including Jilin and Siping. This paper puts forward relevant measures to promote the further decoupling of construction land expansion and economic growth in order to realize the sustainable use of land resources.

Reflections and Explorations on the Decremented Regulation of Construction Land in the New Beijing City Master Planning

Construction land use has always been a key point for the planning department to practice national transformation strategy. In the new round of compilation of Beijing City Master Plan, the management of construction land use is under the rigid restriction of the bearing capacity of resources and the environment. Setting the upper-limit of the population size, a general strategy of decremented development of urban-rural construction land has been put forward, in order to realize a transition from quantitative expansion planning to qualitative upgrading planning. By "decremented development," "decremented" means a more rigid bottom-line restriction, and "development" means a more scientific allocation of resources. From the master planning level, the new Beijing City Master Plan establishes a comprehensive control framework and restrictive index system from perspectives including land use scale, construction scale, space boundary, urban and rural structure, land use structure, and cross-boundary collaboration; and in practice, it promotes strict management methods by setting up a dismantle-construction land ratio, dismantle-construction building area ratio, employment and residence land ratio, and "two lines and three districts," which is an exploration on the planning management method of construction land use that is stock-based and decremented master planning. Considering that decremented development is a major reform and a special challenge to planning implementation, the Beijing City Master Plan carries out explorations in terms of the planning management method, land policy, jurisdiction division, assessment and supervision, etc.

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。

论集体公益性建设用地使用权的法律构造

集体公益性建设用地使用权的法律供给严重不足,学者观点又存在较大分歧。在“房地一体”登记下,集体土地所有权的代表行使主体享有独立的集体公益性建设用地使用权,并应平等、补充适用《土地管理法》与《民法典》。界分村级组织集体公益性建设用地使用权的登记主体是村民委员会还是农村集体经济组织,应尽量登记给村民委员会。集体公益性建设用地使用权的设立宜采取拨用而非划拨的方式,并经登记生效;其不能抵押,但可以在不降低公益效用的前提下,经政府机关批准和集体成员民主议定,采取转让、互换等方式处分。集体公益性建设用地使用权因集体公益收回应当符合比例原则,因经营性转化应当明确转化的条件、程序、方式和收益分配。

集体经营性建设用地入市制度的实施与司法应对

落实和实施集体经营性建设用地入市制度对于构建城乡统一的建设用地市场意义重大。现行法虽然为集体经营性建设用地入市提供了许多实体、程序规则,但存在规范不衔接乃至规范冲突等问题,为此,须从司法裁判视角确定各类相关规则的规范功能和规范要求。具言之,在司法审查过程中,集体经营性建设用地应采用“集体土地所有权依法登记且入市地块符合现行有效的国土空间规划”标准进行认定,集体经营性建设用地入市的决策应遵循“全体具有完全民事行为能力的成员三分之二以上参加并同意”规则,集体经营性建设用地入市合同应认定为民事合同,集体经营性建设用地入市监管协议的法律性质应认定为行政协议。围绕集体经营性建设用地入市合同和监管协议产生的纠纷应当分别通过民事诉讼和行政诉讼程序加以解决。

宁夏城市建设用地节约集约利用与高质量发展耦合协调研究

当前中国进入高质量发展阶段,缓解城市快速扩张伴随的土地利用粗放问题对城市可持续发展具有重要意义。现有研究多单方面关注城市建设用地节约集约水平或高质量发展状态,较少讨论两系统间的耦合协调关系。通过构建多维指标体系,测度2018年宁夏22个区县城市建设用地节约集约利用水平和高质量发展状态,并采用耦合协调度、相对发展度和影响协调力分析两系统间的耦合协调关系。结果表明:(1)2018年宁夏城市建设用地节约集约水平呈现出“中部低、南北高”的分布态势,而高质量发展水平呈现出“西北高、东南低”的空间分布格局。(2)两系统耦合协调度空间上呈现出“中部低、南北高”的分布格局,宁夏大部分区县处于基本协调状态且两系统关系呈良性循环。(3)创新和安全子系统对两系统的耦合协调度普遍起反向阻滞作用;绿色和协调子系统对两系统的耦合协调度普遍起正向推动作用。研究结果可为黄河流域高质量发展情境下促进建设用地节约集约利用提供实证依据。

生产要素下乡的障碍性因素及破解之策——基于S县J农业项目的调查研究

城乡要素的双向有序流动是在我国实施乡村振兴的战略背景之下,实现城乡融合发展的关键支撑,而城乡融合则是建立在生产要素双向自由流动的基础之上的,但是当前我国的城乡要素却只呈现出由乡村向城市的单向流动,从城市向乡村的流动还存在着障碍。为了深入研究生产要素下乡的障碍性因素,本文采取案例分析法,通过对S县J农业项目落地过程的考察和分析,研究发现阻碍生产要素下乡的主要障碍性因素为:由于在我国现行的农村土地制度、政策、运行机制之中均存在着与现代农业及乡村旅游业发展不相适应的成分,因而由此引发的农用地供地障碍和农村集体经营性建设用地供地障碍。为了破解生产要素下乡的障碍性因素,本文提出如下建议:1)我国应以土地确权为基础,积极开展对农用地经营权的股份化改革,从而可以将农用地经营权“化零为整”集中管理,最终以达到解决农用地规模化流转困难的目的。2)我国应通过重新研究制定乡镇的行政区划标准,来进行相应的调整改革,从而以打破土地流转的行政壁垒。3)我国应对农村集体经营性建设用地的空间置换机制进行深入改革,并完善相应的土地入市机制,从而可以将农村分散、闲置的集体经营性建设用地整合利用,并可以为生产要素下乡提供足够的空间载体。4)我国应优化农村集体建设用地的空间布局,促使其可以充分发挥出集聚产业要素、保障社会服务、促进文化发展等诸多功能,进而以形成主城区与区域中心镇相结合的空间格局,并可以为生产要素下乡提供畅通的渠道。

数字乡村建设、城乡融合发展与县域经济增长

数字乡村建设能够有效盘活农业资源,促进城乡要素双向流动,以城乡融合发展的方式为县域经济增长注入新动能。基于北京大学新农村发展研究院发布的2018—2020年数字乡村指数与县域数据的匹配数据,考察数字乡村建设对县域经济增长的影响及其作用机制。研究结果表明:数字乡村建设能够促进本地与毗邻地区的县域经济增长;数字乡村建设通过促进城乡劳动力双向流动、城乡市场有效对接与城乡产业融合发展赋能县域经济增长;乡村经济数字化对县域经济增长的促进作用最大,数字乡村建设赋能县域经济增长的影响效应从东部地区向西部地区呈现逐渐递减的态势,在县域经济发展水平较高地区的促进作用更大;数字乡村建设赋能县域经济增长具有边际效应递增的非线性特征。

集体经营性建设用地出让制度的现状、问题及完善对策

长期以来,我国建设用地市场的供应以政府为主,农村土地难以直接进入用地市场,因而农村集体可获得的土地收益较为有限。在实施乡村振兴战略的背景下,完善集体经营性建设用地的出让制度,需要立足于集体经营性建设用地出让的法律规定、国家政策安排以及实际出让情况。当前,集体经营性建设用地面临出让主体制度不完善、增量范围不清晰、出让收益分配制度不明确、处分权能不健全、统一交易市场未形成等方面的制约。为推动农村集体产权和土地管理制度改革,应当从完善出让主体制度、增量机制、出让收益分配制度,以及保障处分权能、构建统一用地市场等方面对集体经营性建设用地出让制度加以完善,以集体经营性建设用地出让助力乡村振兴。

基于遥感影像数据和POI数据的城市建设用地提取

城市建设用地能够反映城市在地域空间上的分布形态,是衡量城市发展的重要指标。针对城市建设用地的提取,本文提出一种结合遥感影像数据和兴趣点(point of information,POI)数据的城市建设用地提取方法。首先根据珞珈一号夜间灯光数据和归一化植被指数(normalized difference vegetation index,NDVI)的亮度、纹理等信息进行多尺度面向对象检测,得到一个城市建设用地;然后使用地理探测器对POI数据进行筛选,利用筛选后的POI数据进行核密度分析提取得到另一个城市建设用地;最后通过对两种提取结果进行融合,得到精确的城市建设用地。结果表明,本方法提取的城市建设用地完整性好,与实际的城市建设用地较为吻合。该方法可为使用多源数据在市级尺度上提取城市建设用地提供参考。
