中国旅游业碳生产率区域差异及其格局演变:1995—2014

利用"自下而上"法核算1995—2014年中国大陆30个省(市、区)旅游业碳生产率,采用标准差、变异系数等指标衡量旅游业碳生产率区域差异,并通过空间自相关分析探讨中国旅游业碳生产率区域差异格局演变特征。结果表明:1995—2014年中国旅游业碳生产率总体呈增长趋势,但增长幅度不大,其年均增长率为2.07%,旅游业碳生产率具体数值由1995年的1.120 1万元/t增长至2014年的1.653 0万元/t;旅游业碳生产率区域差异明显,但区域绝对差异和区域相对差异均逐步缩小;旅游业碳生产率空间分布不均,总体呈东高西低的空间格局;旅游业碳生产率的空间分布存在显著正空间自相关性,以及局部的不连续性;旅游业高碳生产率集聚区域主要分布在华北地区,以北京、天津、河北为主要代表;旅游业低碳生产率集聚区域主要分布在西北地区,以新疆、青海和陕西为主要代表;中国旅游业碳生产率整体水平较低,多数省区位于旅游业低碳生产率行列,研究期内旅游业低碳生产率的区域重心逐渐由西部向中部转移。基于上述结论,本文提出针对性建议:政府应制定低碳旅游相关的系列标准规范、行动方案以及保障性政策等,同时应加大对先进低碳技术和低碳设备的引进与推广;各省区应秉持低碳发展理念并将其融入目的地开发与管理之中;旅游企业应积极利用新能源、新材料和新技术,研发低碳旅游系列产品与服务;加大宣传生态环保理念,引导旅游者树立低碳旅游意识,优先选择低碳旅游景区和低碳出行方式,自觉抵制高碳排旅游活动。     

Temporal-spatial Characteristics of the Urbanization of Rural Land in Xinjiang

Relying on remote sensor technology, GIS and Land-sat TM digital images, the authors use spatial and statistical analysis to examine the temporal-spatial characteristics of the change caused by urban Construction in Xinjiang＇s rural areas from the end of the 1980s to the end of the 1990s. The primary findings show the following： 1） The urban construction in rural areas has increased drastically. The expansion speed of urban land use has accelerated over the past decade. The sub-land use changes caused by the urbanization of rural are characterized by salient regional differentiation among the three main regions and among the 85 counties of Xinjiang. 2） The shift of land use is mostly characterized by cultivated land and grassland being used for urban and industrial projects. Moreover, this change of land use is characteristic of regional differences. 3） Factors of rural-urban construction land use changes in Xinjiang, are undoubtedly affected by natural environment, social, economic conditions, and to a larger degree by population growth, GDP development and industrial development.     

International mechanism for loss and damage from climate change: recommendations for related work in China

Loss and damage (L&D) from climate change has threatened the sustainable development of humankind, while the progress of mitigative and adaptive measures carried out under the international multilateral framework has been slow. The scientific community and policymakers have placed increasing emphasis on the international L&D response mechanism as a potential direct solution. This paper reviewed the origins of such a mechanism, with an in-depth analysis of the related connotations. A review of the existing situation in China on work related to L&D arising from climate change was conducted, followed by a summary of the findings. Finally, measures and recommendations to improve China’s efforts were proposed in this issue.     

The impact of climate change on tourism in Germany,the UK and Ireland: a simulation study

We downscale the results of a global tourism simulation model at a national resolution to a regional resolution. We use this to investigate the impact of climate change on the regions of Germany, Ireland and the UK. Because of climate change, tourists from all three countries would spend more holidays in the home country. In all three countries, climate change would first reduce the number of international arrivals—as Western European international tourist demand falls—but later increase numbers—as tourism demand from increasingly rich tropical countries grows. In Ireland and the UK, the regional pattern of demand shifts is similar to the international one: tourism shifts north. In Germany, the opposite pattern is observed as the continental interior warms faster than the coast: tourism shifts south.

电力发展对中国经济增长的影响及其区域差异

1990年以来,随着中国电力体制改革的深入,电力基础设施与经济同步发展。由于电力生产与电力消费存在着显著的空间差异,电力发展对经济增长的影响可能存在空间差异。本文利用1990—2011年省级面板数据,基于增长回归模型,采用动态面板分析方法,以电力投资率和发电装机容量作为衡量电力发展的指标,检验电力发展对经济增长的影响以及这种影响的区域间差异。实证研究的主要发现如下:首先,电力发展对经济增长有显著的正面影响,而且其长期影响明显高于短期影响。其中,电力投资率每增加1个百分点,短期经济增长率提高0.076个百分点,长期经济增长率提高0.493个百分点;发电装机容量每增加1个百分点,短期经济增长率提高0.381个百分点,长期经济增长率提高1.905个百分点。其次,电力发展对经济增长的影响具有显著的地区差异,对东部地区的经济增长影响显著高于西部地区。其中,电力投资率增加1个百分点对东部地区的经济增长率影响高于西部地区达0.913个百分点;电力装机容量增加1个百分点对东部地区的经济增长率影响高于西部地区达0.959个百分点。实证结果表明,电力发展对各地区经济增长影响是不平衡的,这种影响对区域经济协调发展起到了负面作用。基于实证研究,给出如下政策建议:首先,考虑到中国经济在未来20年中仍将保持较高增速,中国应继续促进电力发展投资,以促进经济增长。其次,从政策导向来看,电力发展政策应当充分加强电力发展对区域协调发展的作用,使得西部地区能从电力输出中获得更高收益,提高电力发展对区域经济增长影响的公平性。     

Analysis of the efficiency of regional tourism based on DEA window technology

In this study, data envelopment analysis is used to measure the tourism efficiency of 31 regions in China according to the panel data from the year 2000 to 2010. The conclusion shows that the efficiency of tourism industry is on the rise as a whole, while the diversity of every region becomes more and more apparent. High efficiency appears in east regions like Beijing, Tianjin and Shanghai where the economy is developed, and regions like Jilin, Sichuan and Gansu in the midland and west show low efficiency.     

城市建设用地扩张的区域差异及其驱动因素

中国城市建设用地规模随着工业化、城镇化的不断发展而日益剧增。受经济、社会等诸多驱动因素影响,各地建设用地扩张在时间维度、空间维度都存在明显的区域差异,对上述问题进行全面考察,有助于理清建设用地扩张的机理,促进土地集约、节约利用。将城市建设用地扩张的影响因素分为政府推动和市场拉动两个方面,采用基尼系数及基于半对数回归方程的Shapley值分解方法,考察了2006—2015年中国大陆31个省(市、自治区)城市建设用地扩张的区域差异及其驱动因素的贡献程度。结果表明:(1)2006—2015年,中国城市建设用地扩张的区域差异比较明显,衡量差异程度的基尼系数先升后降,最后稳定于0.3左右;(2)财政赤字率、经济政策执行力、经济增长、人口城镇化等因素对建设用地扩张具有正向驱动作用,产业结构调整、建设用地利用效率等因素对建设用地扩张具有负向驱动作用;(3)经济增长、财政赤字率、经济政策执行力等三个因素对建设用地扩张区域差异的贡献最大;(4)影响我国东、中、西三个区域建设用地扩张的主导因素不尽相同。为此,应从促进区域经济平衡发展、拓宽政府融资渠道、加快产业结构调整、提高建设用地利用效率等多方面入手,破解城市建设用地过度扩张的困局。     

Empirical research on construction of a measurement framework for tourism carbon emission in China

According to the logic process of carbon reduction in China which arises from the measurement to reduction, from reduction to offsetting, the measurement of carbon emission in the tourism industry was the first and key step. Based on the life cycle assessment theory and input–output analysis, this article used economic and environmental measurement technologies, The System of National Accounting (SNA), Tourism Satellite Account (TSA), System of Integrated Environment and Economic Accounting (SEEA), and so on, and built up a top-down carbon emission analysis framework for the tourism industry and estimated carbon emission of the tourism industry in China in 2007. The finding showed that the total carbon emission of the tourism industry in China in 2007 was 169.78 million tons, covering 2.71% of carbon emission of all industries in China in 2007, and 2.44% of the total carbon emission in China in 2007. The direct carbon emission of the tourism industry in China in 2007 was 73.56 million tons, including transportation (50.14 million tons), sightseeing (1.33 million tons), lodging (4.19 million tons), accommodation (4.73 million tons), shopping (8.14 million tons), entertainment (0.67 million tons), communication (0.45 million tons), and others (3.90 million tons). The indirect carbon emission of the tourism industry in China in 2007 was 96.23 million tons, mostly contributed by coking, gas, and petroleum processing industries, transportation and warehousing industry, machinery and equipment manufacturing industry, and food manufacturing and tobacco processing industry, which covered 57%.

Then, the paper gets the evaluation scores of every province by applying the principal components analysis and statistical package for the social sciences processing. Second, the paper builds the tourism development-tourism HR matrix and divides the matrix into four quadrants. Finally, the paper points out the problems of tourism HR that exist in the 31 provinces and puts forward development strategy.     

Global progress in climate change adaptation policies and its implication for China

This paper reviews the progress in climate change adaptation (CCA) policies both under the United Nations Framework Convention on Climate Change (UNFCCC) and in major regions and countries, including the EU and its major member countries, the influential developed countries in the Asia-Pacific region, the emerging economies and the least developed countries (LDCs). The progress made in China in CCA policies is also reviewed and compared with that in other countries. Finally, good international practices are proposed for China’s policy development. It is found that adaptation has been given the same priority as mitigation since the twenty-first century with regard to climate change-related actions. The topics related to adaptation in the international climate change negotiations under the UNFCCC have evolved from mechanisms for finance and technology development and transfer exclusively in the early stages to implementation of practical adaptation programs and actions. Since 2006, major developed and developing countries have frequently set forward specific CCA policies or general climate change policies involving adaptation in the form of laws, frameworks, strategies, and plans. The LDCs have also been working on National Adaptation Programmes of Action and subsequent National Adaptation Plans with the support from the financial mechanisms under the UNFCCC. Therefore, globally, it has become a common practice to develop national or regional policies to plan and guide CCA actions. China has established climate change policies involving adaptation at the national, regional, and sectorial levels since 2007. However, these policies have strong limitations in their knowledge base, strategic positioning, contents, and implementation mechanisms, e.g. lack of a sound knowledge base, an international perspective, clear responsibilities for policy implementation, and appropriate monitoring and evaluation mechanisms. It is recommended that China should further strengthen its technical capabilities in climate change projections as well as impact, vulnerability, and risk assessment, and develop methodologies and techniques for the preparation, impact assessment and implementation of CCA policies. Furthermore, future CCA strategies or plans should be developed with an emphasis on China’s vision and strategic position on the world stage.     

生态脆弱区自然资本可持续利用及驱动机制--以宁夏为例

自然资本的分类测度和分区管理是可持续发展领域的核心议题。文章基于改进后的三维生态足迹模型,分析了2008—2017年宁夏及其各地级市自然资本利用的时空演变特征,并运用偏最小二乘法揭示了自然资本利用演变的驱动机制,旨在为生态脆弱区自然资本的可持续利用、社会经济的协调发展和生态文明建设提供参考。结果显示:①10年来宁夏人均生态足迹以年均5.01%的速率从3.146 hm²增至4.564 hm²,人均生态承载力相对稳定,人均生态赤字由2.462 hm²扩大至3.839 hm²,自然资本的供需矛盾愈加尖锐;市域尺度上,除固原市外其他各市生态赤字明显,总体上呈由南向北递增趋势。②足迹深度和足迹广度表明流量资本已无法满足需求,对存量资本的消耗成为社会经济发展的常态;市域尺度上,足迹深度呈“北高南低”的分布特征,而足迹广度的空间分布与其相反,二者存在显著的地域互补性。③从地类组分构成来看,林地、草地和水域是全区存量资本消耗的主要方式,耕地尚处于流量资本占用状态,建筑用地已过渡为存量资本;市域尺度上,自然资本利用的可持续性呈“南强北弱”格局,各地类间自然资本利用差异显著。④偏最小二乘回归模型揭示能源消耗、社会消费、经济发展和资源禀赋条件是影响宁夏自然资本利用的显著因素,而人口规模、对外贸易、生态建设、科技进步和产业结构演化对自然资本利用的影响程度较轻;市域尺度上自然资本利用的驱动力差异显著。最后,基于自然资本利用空间分异特征,从供需视角提出了自然资本可持续利用的对策建议和优化路径。

Pros and cons of climate change in China

Climate change strongly affected the structure and functions of natural ecosystems, e.g. the vegetation productivity decreased in the Northeast permafrost region due to the higher temperature and less precipitation, whereas in the Tibetan Plateau, the vegetation productivity increased, owing to the improved thermal resource. Climate change led to reduced precipitation in North and Northeast China and thus the reduced surface runoff. The public needs for energy were changed because of climate change, e.g. the shorter heating period in winter. Climate change profoundly influenced human health, pathophoresis and major projects by increasing extreme events, including frequency and magnitude, and causing more serious water shortage. Under the background of climate change, although the improved thermal resources can be helpful for extending the crop growth period, more extreme events may resulted in more instability in agricultural productivity. Not only did climate change indirectly affect the secondary and tertiary industries through the impacts on agriculture and natural resources, but also climate change mitigation measures, such as carbon tax, tariff and trading, had extensive and profound influences on the socioeconomic system. Further analysis indicated that the impact of climate change presented significant regional differences. The impact had its pros and cons, while the advantages outweighed the disadvantages. Based on the above analysis on the impacts of climate change, we put forward suggestions on coping with climate change. First, scientifically dealing with climate change will need to seek advantages while avoiding the disadvantages of climate change in order to achieve the orderly adaptation to climate change, which is characterized with “Overall best, long-term benefit.” Second, quantitative adaptation should be given more attention, e.g. proposing operational schemes and predictable goals and using uncertainty analysis on adaptation measures. Third, more active coping strategy should be adopted to enhance China’s future comprehensive competitiveness. The strategies include but are not limited to gradually adjusting the industrial structure, intensifying the research and development (R&D) of emission reduction technology and actively responding to the influence of carbon tax, tariff and trading on socioeconomic development in China.

Loss and damage related to climate change: connotations and response mechanism

Global mitigative and adaptive efforts have not been able to effectively address the adverse impacts caused by climate change. Therefore, a direct solution is needed to address the significant resulting loss and damage (L&D). During the United Nations Framework Convention on Climate Change held in Doha in 2012, the issue of responding to L&D arising from climate change gained sudden traction and became one of the key issues that affected the outcome of the convention. In this paper, a study on the definition and connotations of L&D arising from climate change was conducted, together with an analysis of its relationship with related concepts, namely impacts, vulnerability, and risks. This led to the proposal of an L&D conceptual model that is more comprehensive, with the recognition of the need to address the issue through effective supplementation of existing mitigative and adaptive efforts. A systematic elaboration of an L&D response mechanism was made based on politics, law, and the market, leading to a preliminary presentation of a possible format for an L&D mechanism. Potential academic research directions for L&D were also proposed that could serve as references for the establishment of international and national L&D response mechanisms and related research.     

A Methodology Framework for Regional Land-use Change Studies based on Landsat TM images: A Case Study in Northeast China

Land-use change is an important aspect of global environment change. It is, in a sense, the direct result of human activities influencing our physical environment. This paper analyzed the land-use change in Northeast China during 1985-2000 based on Landsat TM images. It divides Northeast China into five land-use zones based on the dynamic degree model of land-use: woodland/grassland-arable land conversion zone, dry land-paddy field conversion zone; urban expansion zone, interlocked zone of farming and pasturing and reclamation and abandon zone. The findings include the obvious increase of cropland area, paddy field and dry land increased by 75 and 276 thousand hm2 respectively; urban areas expanded rapidly, areas of town and rural residence increased by 76.8 thousand hm2; areas of forests and grassland decreased sharply with the amounts of 1399 and 1521 thousand hm2 respectively; areas of water body and unused land increased by 148 and 514 thousand hm2 respectively.

A Methodology Framework for Regional Land-use Change Studies based on Landsat TM images: A Case Study in Northeast China

Abstract

Land-use change is an important aspect of global environment change. It is, in a sense, the direct result of human activities influencing our physical environment. This paper analyzed the land- use change in Northeast China during 1985–2000 based on Landsat TM images. It divides Northeast China into five land-use zones based on the dynamic degree model of land-use: woodland/grassland-arable land conversion zone, dry land-paddy field conversion zone; urban expansion zone, interlocked zone of farming and pasturing and reclamation and abandon zone. The findings include the obvious increase of cropland area, paddy field and dry land increased by 75 and 276 thousand hm² respectively; urban areas expanded rapidly, areas of town and rural residence increased by 76.8 thousand hm²; areas of forests and grassland decreased sharply with the amounts of 1399 and 1521 thousand hm² respectively; areas of water body and unused land increased by 148 and 514 thousand hm² respectively. This paper also discusses the driving forces in each land-use dynamic zone and finds that some key biophysical factors affect conspicuously the conversion of different land-use types. The relation between land-use conversion and DEM, accumulated temperature (≤10°C) and precipitation was analyzed and represented. The land-use changes In Northeast China resulted from the changing macro social and economic factors and local physical elements. Rapid population growth and management changes can explain the shaping of woodland/grassland-cropland conversion zone. The conversion from dry land to paddy field in the dry land-paddy field conversion zone, apart from the change of physical elements promoting the expansion of paddy field, results from two reasons: one is that the implementation of market economy in China has given farmers the right to decide what and how they plant their crops, the other factor is originated partially from the change of the dietary habit along with the social and economic development. The conversion from paddy field to dry land is caused primarily by the shortfall of irrigation water, which in turn is caused by poor water allocation managed by local governments. The shaping of the reclamation and abandon zone is partially due to the lack of environment protection consciousness among pioneer settlers. The reason for the conversion from grassland to cropland is the relatively higher profits of farming than that of pasturing in the interlocked zone of farming and pasturing. In Northeast China, the rapid expansion of built-up areas results from two factors: the existence of a small number of towns and the huge potential for expansion of the existing towns and cities. The urban land expanded mainly in areas with a gentle topographic relief and low population density.
