摘要:
为探究中国海外耕地投资活动的发展规律,论文基于GRAIN和Land Matrix的案例统计数据,采用文献资料法、空间计量法,从投资规模的空间格局演变及其发展的影响因素两个方面进行了分析。结果表明:①2004年以后中国海外耕地投资的总体空间集聚效应开始显现,目前在局部已形成明显的空间分化,局部空间集聚效应的高-高集聚区是俄罗斯和东南亚地区;②中国海外耕地投资活动的空间变异影响范围和影响程度经历了一个波动增强的过程,在西北至东南方向的空间变异最为显著,东道国的内部因素已成为影响中国海外耕地投资发展的重要因素;③中国海外耕地投资的发展受地缘政治、地缘经济和地缘文化因素的共同影响,其中东道国农用地比例,谷物单产水平,同中国的声明、宣言和公报总数,对华免签证件数量和驻华领事机构数量5个指标在统计上显著性较高。在中国海外耕地投资发展规模已呈现空间分异趋于稳定发展的情况下,相关机构应当重视对东南亚地区和俄罗斯的投资保护与规划。

摘要:
China's rapid urbanization and urban development has consumed a lot of land resources, which has attracted a great deal of both scholarly and social attention. However, the influence mechanism of urbanization on urban land consumption has not been yet fully investigated. This paper address this gap by proposing the term urban land consumption intensity (ULCI) and exploring the influence of urbanization on ULCI, based on the provincial panel data from 2000 to 2017 in China and the Panel-data Vector Autoregressive (PVAR) Model. The findings reveal that China's urbanization prompts the ULCI. However, this positive influence of urbanization on ULCI is not decisive. The change in the ULCI in China is mainly affected by its own impulse. This paper further analysis the decomposition results of urbanization, and finds that population urbanization (PU), economic urbanization (EU), spatial urbanization (SU) and social urbanization (SCU) can explain the change of ULCI in China to some extent. From the variance decomposition, EU has the largest contribution rate to the changes in ULCI, followed by SCU, SU, and PU. Policymakers should actively promote the coordinated development of different types of urbanization, and comprehensively evaluate the actual and optimal ULCI in different cities. © 2020 Elsevier Ltd

摘要:
Market-oriented allocation of land resources is one of the main economic reforms in China. However, the influence of land transfer marketization (LTM) on green total factor productivity (green TFP) and its mechanisms remain unknown. Based on panel data of 30 provincial administrative regions in China from 2004 to 2016, this study attempts to establish mechanism among LTM, industrial structure and green TFP, which is measured by the Slack Based Measure DEA (SBM-DEA) model containing undesirable output, and empirically estimates the impact of LTM, the rationalization and optimization of industrial structure and their interactions on green TFP further. The results show that: 1) LTM has a significant promoting effect on the improvement of green TFP in China, and the effect is also significant in the eastern, central and western regions as well, indicating that the application of land transfer policy to regulate regional economic development is widespread in China. 2) The rationalization of industrial structure has significantly promoted the development of green TFP in China, as well as at the regional levels, and the effect decreases from the western region to the central and eastern regions. The optimization of industrial structure also has a promoting effect on green TFP in China and all the regions, but the regional differences of the effect are contrary to that of the rationalization of industrial structure, with a decreasing trend from the eastern region to the central and western regions. 3) The interaction between LTM and the rationalization of industrial structure has significantly inhibited the improvement of green TFP in China, and the regional variations of the restraining effect are higher in the western region, followed by the central and eastern regions. The interaction between LTM and the optimization of industrial structure also has a negative effect on green TFP in China, and the regional variations of the effect showing the decreasing trend from the eastern region to the western and central regions. Therefore, China should continue to adhere to the market-oriented urban land transfer system reform, actively play the role of the government in the industrial upgrading and industrial transfer, and formulate a differentiated land transfer system and industrial development policies based on the economic development and industrial characteristics of various regions, so as to achieve the sustainable development of China’s economy and society.

摘要:
This paper focuses on the cyclicality of rural public expenditure in China. We employed two types of instrumental variables to estimate the effects of fluctuations in GDP on rural public expenditure based on China’s provincial/municipal panel data during 2000–2016. The results show that once the corresponding endogeneity is controlled, whether in the long or short term, China’s rural public expenditure is characterized by procyclical behaviors. However, when regional differences are taken into account, the procyclicality of China’s rural public expenditure is related to the degree of economic development in the region. Specifically, through grouping regression of population density, public service provision per capita and central transfer payment per capita, in the short term, lower economic development usually leads to more obvious procyclicality; in the long term, in the areas with economic development above the median, rural public expenditure is acyclical. This study provides empirical evidence for the procyclical rural public expenditure in developing countries. © 2020, Springer-Verlag GmbH Germany, part of Springer Nature.

摘要:
Overseas farmland investment is an “external program” contrary to the “internalization program” such as multiple planning integration and farmland protection, to solve the contradiction of food security and urbanization during the process of China's development. Though overseas farmland investment being a new investment tide for decades, research on overseas farmland investment is still in its infancy, with limited research dimensions and insufficient depth. How to establish a scientific and reasonable selection model of the host country for China as well as other countries has become an urgent academic and practical issue to decrease the investment risks. This paper analyzes the spatial distribution of China's overseas farmland investment with the investment samples from 2000 to 2017 and proposes its operational strategy. Here are the conclusions. (a) The obvious imbalance of the distribution of China's overseas farmland investment. Further research from a global perspective finds that the existent distribution pattern of China is not optimal. (b)The correlation analysis result shows the trends of overseas farmland investment with political stability and benefits seeking. (c) Host countries most suitable for overseas farmland investment are concentrated in Southeast Asia and along the equator in Africa and Latin America. (d) The existent distribution pattern for China's overseas farmland investment needs some proper adjustment. China should increase the scale of overseas farmland investment in non-traditional regions while strengthening the status of the core investment regions in Southeast Asia, especially in Sub-Saharan Africa and Latin America. © 2019 Elsevier Ltd

摘要:
The relationship between rural labour transfer and cultivated land use has always been a hot topic in academic field and government management. Here, by using the large-scale survey data of 1,868 farmers from 37 villages in Jianghan Plain and the low-hill areas in southeastern Hubei province, we investigated the relationship between rural labour force transfer and decision-making in cultivated land use from the perspective of terrain heterogeneity. The findings indicate that under different terrain conditions, there are significant differences in the decision-making of farmers concerning cultivated land use, leading to different land use efficiencies in different areas. Specifically, rural labour force transfer enhances land use efficiency in plain areas; however, it does not affect that in the low-hill areas. In addition, we found that in the plain areas, improving the quality of rural household labour can increase the cultivated land use efficiency, while in low-hill areas, enhancement of geographical accessibility is the key to improving land use efficiency. © 2019 The Author(s).

摘要:
不同的政策工具类型与结构将形成不同的耕地保护政策安排与行为约束,直接影响耕地保护政策目标实现程度和政策实施效果。本文将耕地保护涉及的政策工具划分为命令控制、经济激励和宣传引导三类,在设计出政策工具影响耕地保护效果的理论框架与研究假设后,以中国2001—2016年时序数据为基础,利用向量自回归模型实证揭示了不同类型政策工具对中国耕地保护效果的影响方向及贡献程度。结果表明:①命令控制工具、经济激励工具和宣传引导工具均与中国耕地保护效果之间存在长期稳定的均衡关系。②命令控制工具、宣传引导工具与中国耕地保护效果之间存在单向因果关系,它们是中国耕地保护效果变化的格兰杰原因,但是反过来均不成立,经济激励工具则与中国耕地保护效果之间存在双向因果关系。③中国耕地保护效果在很大程度上是受自身冲击的影响,表现出依赖自身惯性的变化特征,但是这种贡献率随着滞后期数的增加而逐渐降低,由第1期的100%变化至第10期的41. 30%。④命令控制工具、经济激励工具和宣传引导工具在整个分析期内均对中国耕地保护效果提升有积极作用,且从方差分解结果来看,三类政策工具对耕地保护效果的贡献率在滞后10期时都表现出不同幅度的上升趋势,其中经济激励工具的贡献率最高,其次是命令控制工具,宣传引导工具的贡献率最小。未来不仅要根据耕地保护面临的新形势进行政策工具创新,同时也要注重完善政策工具的内部结构,充分发挥不同类型政策工具的作用与功能,实现合力最大化。

摘要:
In a city, housing price varies with location. Thus, housing price plays an important role in detecting the spatial pattern of the city. Spatial interpolation methods have been widely used for simulating and predicting urban housing prices. In this paper, the Ordinary Kriging interpolation method is used for producing the digital elevation model (DEM) of urban housing prices. Based on the three-dimensional DEM of urban housing price, this paper develops a novel approach for geo-visual analytics of urban housing prices. To investigate and visualize the spatial morphology of housing price, we design the Water-flooding, Section-cutting and Belt-floating methods, and implement these methods with the 3D-analyst module in GIS environment. Then, we take Wuhan City as a case, apply this approach to analyze the complex spatial morphologic characteristics of the DEM for housing price and visualize the results from the multidimensional perspectives. The results show that the Water-flooding method effectively supports the investigation of the top areas of surface changes; Section-cutting method performs well in examining the profile or cross-section of the urban housing surface; and Belt-floating method is helpful for detecting the spatial variance of the urban housing surface through the routes of specific lines. The results demonstrate that the proposed approach works better than traditional methods in describing the complex spatial morphology of urban housing prices, and has an advantage in visualizing the analysis results.

摘要:
构建合适的量化分析模型是科学把握耕地利用状况及利用效率的基础性工作,可为制定合理有效的耕地资源管控政策,实现耕地利用与生态环境的协调发展提供决策依据。为了更准确地反映耕地利用系统的复杂性、动态性及差异性等特征,鉴于随机森林的基本思想,运用随机抽样Bootstrap法在合理构建分类树的基础上,构造了耕地利用效率测度的RF模型,进而以中国粮食主产区172个城市为例训练该模型并将其运用至2003-2015年的耕地利用效率测度中,同时将BP神经网络和熵权法作为对比验证其一致性、代表性和优越性。结果表明:(1)耕地利用效率测度的RF模型不受量纲限制,运行所需参数少,运算过程简化,能够较为精确地模拟各评价指标间的复杂联系,科学量化各评价指标对耕地利用效率的贡献。(2)对同一空间单元的效率值而言,RF>BPNN>EW,RF与BPNN所得效率值的总体分布格局相似,且均与EW的测度结果存在较大差异。(3)从评价结果与现实的匹配度和精度表征参数来看,RF的测度结果与自然和社会经济发展等客观事实更相符,具有较高的适用性与可靠性。同时,与其余两种常用模型相比,RF能够降低计算复杂度,提高训练效率,其测度结果的相关系数R为0.8685,M_(RPD)为2.3533,且具有最小M_(MSE)0.0174和M_(MAE)0.0211,更适用于复杂非线性特征的耕地利用效率研究。

摘要:
研究目的:考察土地出让市场化与产业结构优化对城市绿色全要素生产率的影响程度及其作用机制。研究方法: SBM-DEA模型,动态面板广义矩估计(GMM)。研究结果:(1)无论是系统GMM还是差分GMM,土地出让市场化对绿色全要素生产率的影响系数均显著为正,产业结构合理化和高度化的影响系数也均显著为正,但后者的作用程度要明显大于前者;(2)土地出让市场化与产业结构合理化的交互项对绿色全要素生产率的影响系数为负,土地出让市场化与产业结构高度化的交互项对绿色全要素生产率的影响系数为正,且均通过显著性检验。研究结论:土地出让市场化总体上促进了绿色全要素生产率的发展;从作用机制来看,土地出让市场化导致了产业结构合理化的反向发展,抑制了绿色全要素生产率的提升;同时,也促进了产业结构高度化的正向发展,进而对绿色全要素生产率有提升作用。鉴于此,提出:(1)地方政府应继续坚持以市场化为导向的城市土地制度改革;(2)政府应适时引导产业结构调整,促进产业结构转型和升级,更加重视经济增长与环境保护的协调发展。

摘要:
以长江经济带及其上、中、下游地区为研究对象,从理论上刻画了区域一体化影响土地财政依赖的内在机理,并在考虑空间滞后效应的基础上,采用空间动态面板模型考察区域一体化及其分解指标对土地财政依赖的影响。结果发现,区域一体化对土地财政的"依赖效应"具有地区异质性,具体表现为:(1)长江经济带整体及其中、下游地区的区域一体化与土地财政均存在显著倒"U"型曲线关系,当三个区域的区域一体化水平分别达到0.889 6、0.964 5和0.967 1,即约2049年、2057年和2031年左右,各区域土地财政依赖将会降低,而上游地区区域一体化每增加1%,土地财政依赖将增加0.603 9%。(2)从区域一体化各分解指标来看,经济一体化与土地财政依赖的倒"U"型关系最为显著,且长江经济带将在经济一体化达到0.963 2时进入全域范围的土地财政依赖下降阶段。而社会一体化每提高1%,土地财政依赖将增加0.011 7%~0.121 6%。此外,仅在长江经济带整体尺度下,空间一体化与土地财政依赖符合倒"U"型的理论假说,而制度一体化与土地财政依赖的倒"U"型关系则在上、中、下游分区域尺度下呈现。为了合理利用土地财政,推动和谐治理,从"优化区域空间联动环境""制定差异化发展策略"及"完善监督和预警体系"等方面提出对策与建议。

摘要:
Urban sprawl and its eco-environmental impacts are crucial components of global environmental change research, and a core issue for sustainable development. In this study we used a Pressure-State-Response (PSR) system to develop a theoretical framework, in which the total eco-environmental effects of urban sprawl (EEUS) were divided into pressure, state, and response. A corresponding index system was then constructed to evaluate the different kinds of EEUS in China's 30 provinces from 2003 to 2015, and temporal and spatial characteristics are explored through spatial autocorrelation analysis. We found that 1) pressure, state and response EEUS not only had differences but also strong connections. These three kinds of eco-environmental effects also had different causal mechanisms and their contributions to the total EEUS were different. 2) The pressure, state and response, as well as the total EEUS, increased from 2003 to 2015. However, there were clear disparities in EEUS across the eastern, central, western and northeast regions. EEUS results for the eastern and northeast regions were higher than in the central and western regions. 3) There was significant spatial dependence and heterogeneity in EEUS. Overall, the spatial difference in EEUS was mainly caused by “HH” and “LL” cluster types. These results have significant implications for theoretical guidance and policy efforts. We conclude that a better eco-environment in the process of urban sprawl can be achieved by improving the quality of urban development and enhancing government management. © 2019

摘要:
以中部地区80个地级以上城市为研究对象,采用核密度估计、探索性空间数据分析和空间计量模型,探究中部地区地级以上城市2000-2016年土地城镇化水平差异的时空特征及影响因素.结果 表明:①中部地区土地城镇化水平总体上呈上升态势,平均值从2000年的0.66%增长到2016年的1.36%,且城市间差距逐渐加剧.②中部地区土地城镇化水平表现出显著的全局空间正自相关性,并呈现由强集聚向弱集聚转化的演变特征;其空间集聚形态可分为“高—高”集聚型、“高—低”极化型、“低—高”塌陷型、“低—低”均质型4种类型,不同类型城市的分布特征存在差异.③中部地区土地城镇化水平冷热点区的空间分布具有相对稳定性,大致呈现出“东热西冷”的空间分布状态.④中部地区土地城镇化水平差异受到人口规模、经济发展、产业结构的共同影响.

摘要:
从理论层面揭示区域一体化影响城市土地利用效率(ULUE)的内在机理,构建区域一体化背景下"规模+结构+集聚"的ULUE测度体系,并综合利用小波神经网络、空间分异模型和空间回归分析探索2003-2015年长江中游城市群ULUE的空间关联特征及其影响因素。结果发现:①区域一体化背景下长江中游城市群ULUE从2003的0.561 4增长至2015年的0.811 1,且呈现出明显的区域差异。②ULUE并非随机分布,而是具有空间上的关联特征和集群趋势。且由于不同集聚区内扩散效应在空间上渗透不均衡,其关联性主要表现为空间依赖性和空间异质性。③区域一体化背景下长江中游城市群ULUE在空间关联上具有"近水楼台先得月"和"门当户对"的特征,地理位置的空间相邻、投资消费结构和产业结构的相似是其空间关联的主要成因。

摘要:
文章构建了实体经济、科技创新、现代金融与人力资源协同发展综合评价指标体系,通过因子分析和耦合协同度评价模型,对中国八大区域的实体经济、科技创新、现代金融与人力资源协同发展水平进行测度。结果表明:西南地区实体经济水平滞后于其科技创新、现代金融、人力资源水平;大西北地区和东北地区的科技创新、现代金融、人力资源水平滞后于实体经济水平,这种失调在进一步的恶化,相比之下,长江中游地区协同发展水平有了较大幅度的改善;三大沿海地区的协同发展水平相对较高,但在三大沿海地区内部存在异质性。
