所有制结构变迁影响城乡收入差距的实证检验——基于面板协整的方法

所有制结构变迁是居民收入差距的根本原因,利用1995-2008年30个地区的数据进行面板协整检验表明：国有经济、集体经济与城乡收入差距存在协整关系,公有制经济和非公有制经济分别与城乡收入差距也存在协整关系;国有经济、公有制经济能缩小城乡收入的差距,而集体经济和非公有制经济则扩大城乡收入的差距。     

中国旅游业发展的省区差异及变化

科学审视省区旅游业发展的差异,是实现中国旅游业科学发展的基本前提.文章通过选取国内旅游人数、入境旅游人数、国内旅游收入、旅游外汇收入、旅游总收入相当于GDP百分比、旅游业就业人数占社会总就业人数的百分比等表征旅游业发展水平的6大统计指标,运用多元统计分析方法,评估了中国2000年与2010年旅游化指数的省区差异,发现近10年来中国旅游业发展仍然呈现出显著的区域非均衡性,一些中西部后发优势的省区旅游化程度在明显上升.其中,区位与资源禀赋、经济发展水平、政府政策、基础设施、节庆事件等是导致各地旅游化程度差异及其变化的主导因素.     

再论加快我国行政区划体制的改革与创新

新时期,我国的政府职能转变、交通通讯技术以及城市化加速发展使行政区划管理的基础条件发生了变化,同时提供了改革创新的新动力。因此,我们必须思考加快我国行政区划体制的改革与创新。     

基于GIS和RS的流转耕地用途变化研究——以重庆市忠县为例

基于GIS和RS技术,以重庆市忠县为例,对区域2002～2007年农地流转中耕地的用途变化的数量特点、空间差异进行了研究。研究表明：流转耕地的用途变化趋势主要是耕地变为建设用地、耕地变为园地等其他农地、种粮田变为非种粮田,流转耕地总的用途变化率达69．13％。流转耕地在空间分布上存在着差异,初步了解农业比较效益低和农地流转机制不健全是推动流转耕地用途变化的主要原因。     

旅游发展下客家妇女的地位变迁研究--成都龙泉洛带古镇的个案调查

关注旅游发展下客家妇女地位变迁状况,有益于深化旅游对东道主女性影响研究和客家文化变迁研究。以四川龙泉洛带古镇为例,采取问卷调查与个案访谈法,综合采用定量和定性分析,探究旅游发展下洛带古镇客家妇女家庭地位和社会地位的变迁状态、变迁特点和变迁原因。研究表明,旅游发展影响洛带客家妇女地位变迁;旅游对洛带客家妇女家庭地位变迁影响强度大于社会地位变迁,且更易于被感知;旅游参与方式对洛带客家妇女地位变迁程度无明显影响;旅游影响洛带客家妇女地位变迁的原因集中表现在生计、自由空间和家庭分工的改变。     

浙江省不同性质企业科技创新效率的动态变化与比较研究

基于企业的技术异质性,利用DEA和全局前沿M almquist指数方法对2006—2018年浙江省不同性质企业的科技创新效率和动态变化进行了比较研究.结果表明:①2006—2018年,浙江省不同性质企业的科技创新效率均值较低,差距显著,总体呈波动上升的趋势.2013年以前外商投资企业的科技创新效率处于领先地位,2015年以后内资企业开始长期处于领先地位.考察期间内资企业一直呈追赶势头,特别是国有企业,追赶势头最为显著.②不同性质企业近13年科技创新效率的平均增幅基本一致,大部分年份均处于增长态势.内资企业体现出较强的增长效应,且增长势头比其他两种类型企业平稳.③内资企业全要素生产率上升主要源于组内技术进步.港澳台商投资企业和外商投资企业全要素生产率的变化源于技术效率变化和组内技术变化.3种类型企业的技术领先变化程度均较小.     

How can the EU climate targets be met? A combined analysis of technological and demand-side changes in food and agriculture

To meet the 2 °C climate target, deep cuts in greenhouse gas (GHG) emissions will be required for carbon dioxide from fossil fuels but, most likely, also for methane and nitrous oxide from agriculture and other sources. However, relatively little is known about the GHG mitigation potential in agriculture, in particular with respect to the combined effects of technological advancements and dietary changes. Here, we estimate the extent to which changes in technology and demand can reduce Swedish food-related GHG emissions necessary for meeting EU climate targets. This analysis is based on a detailed representation of the food and agriculture system, using 30 different food items.We find that food-related methane and nitrous oxide emissions can be reduced enough to meet the EU 2050 climate targets. Technologically, agriculture can improve in productivity and through implementation of specific mitigation measures. Under optimistic assumptions, these developments could cut current food-related methane and nitrous oxide emissions by nearly 50%. However, also dietary changes will almost certainly be necessary. Large reductions, by 50% or more, in ruminant meat (beef and mutton) consumption are, most likely, unavoidable if the EU targets are to be met. In contrast, continued high per-capita consumption of pork and poultry meat or dairy products might be accommodated within the climate targets. High dairy consumption, however, is only compatible with the targets if there are substantial advances in technology. Reducing food waste plays a minor role for meeting the climate targets, lowering emissions only by an additional 1–3%.     

Operating small tourism firms in rural destinations: A social representations approach to examining how small tourism firms cope with non-tourism induced changes

This study explores the representation that owners and managers of small tourism firms ascribe to their rural destination and how non-tourism induced changes interfere with this representation and motivate coping as guided by social representations theory. Semi-structured interviews were conducted with twenty-four owners and/or managers of at least one small accommodation property in Gloucester, New South Wales, Australia. The informants became involved in the area's accommodation sector primarily driven by the lifestyle goals embedded in their representation of Gloucester. The perception that mining-induced changes might transform Gloucester into a mining town as opposed to its current representation as a town with a mine has motivated many informants to cope. However, coping is impeded by feelings of powerlessness, perceived uncertainties, and distrust in both government and industry. The findings provide preliminary insight into why and how small tourism firm owners/managers cope when faced with change from the perspective of social representations.     

Progression,Stability, or Decline? Sociological Mechanisms Underlying Change in Specialization Among Birdwatchers

Using a panel of American birdwatchers collected in 1997 and 2002, we tested the extent to which birdwatchers progressed over a five-year period. The impact different career contingencies and life course events had on predicting change in birdwatchers' behavior, skill, and commitment was also examined. Findings indicated that although progression characterized some birdwatchers' participation, involvement by others was better characterized by stability or decline, which was true for each of the indicators used to measure specialization. Career contingencies and life course changes had only a moderate influence on predicting change in the specialization indicators over time. Support from family members and retirement were the best predictors of change in specialization.     

Livestock intensification as a climate policy: Lessons from the Brazilian case

Brazil is trying to identify ways to ally economic growth with climate change mitigation. Productivity gains in livestock have been pointed out as a promising alternative to achieve that goal. Thus, this paper analyses the economic impacts of a policy of productivity gains in the Brazilian livestock. Besides, we evaluate if the policy may conciliate agricultural growth and deforestation control, bearing in mind the reduction of greenhouse gas (GHG) emissions from land-use changes. The analysis was carried out through a computable general equilibrium (CGE) model, tailored to represent land-use changes, GHG emissions and removals. Besides, it made progress modeling the heterogeneity of climate, soils, and emissions in inter-regional models with many regions. The results show that productivity gains can effectively “save” land and thus avoid deforestation, especially in the Amazon and Cerrado (savannah) biomes. The policy also may boost the economic growth, spreading it to other regions of Brazil, like Centre-West and North, and increasing income and consumption in those places. However, as a climate policy, focused on the reduction of GHG emissions, the results may be counterproductive. The net amount issued may increase, as a result of the positive stimulus of the policy on the economy, and GHG emissions are directly related to the economic growth.
