Does economic growth and energy consumption drive environmental degradation in China’s 31 provinces? New evidence from a spatial econometric perspective

The panel data analysis points to economic and social factors contributing to NO_x, PM_2.5, PM₁₀, SO₂, and VOCs in China’s 31 provinces. The spatial correlation analysis using Global and Local Moran’s I values indicates the existence of a significant and positive spatial autocorrelation with respect to environment, economy and energy, and the high spatial correlation is evident in the eastern region, covering the northern part of Yangtze River Delta, Huaihai Economic Zone, and the lower reaches of the Yellow River Economic Belt. The empirical estimation is performed through spatial lag and spatial Durbin models. All emitted air pollutants in 31 provinces have significant spatial dependence and strong spillover effects. There is an inverted U-shaped relationship between emitted air pollutants (NO_x, PM₁₀, VOCs, and PM_2.5) and per capita GDP, which follows the EKC hypothesis. The relationship between SO₂ and per capita GDP does not follow the EKC hypothesis. There is a positive relationship between pollutant emissions and coal consumption, which is consistent with current studies for various countries like Canada, Denmark, UK and US and regions like New York State. However, the effects of science and technology investment on air pollutants are mostly positive, which is not as policy expected.     

论反向旅游

旅游目的地选择是旅游需求与旅游供给双方互动的过程，必须从旅游目的地属性与旅游者属性两个方面予以分析。已有的旅游需求模型用来激发或改变消费者旅行行为策略不敏感，不能满意解释旅游流的时空特性。为此提出“反向旅游”概念，并就其内涵、现实意义及产品开发和营销中应注意的问题进行了深入的讨论。反向旅游的表面是追求景观差异的极大化，实质是追求利益极大化，也是一种跨文化旅蝣行为。和一般旅蝣相比，反向旅蝣的求知求奇效益更大。但“反向旅游”广泛而不普遍，有时只停留在表面。可以从时间、空间、文化等多方面开发反向旅游产品，锁定消费群体开展有针对性的营销。     

破解国企利润上缴的十个难题

国企上缴利润是马克思主义所有制理论的体现，也是深化国企改革的需要。由于这是一项涉及再分配的改革，有“十大难点”需要研解，即国企多年养成的既得利益态势如何改变、现有国资的家底如何理清、国资经营预算应由谁编制、国企按什么原则上缴利润、国企应建立什么样的运作体制、国企要不要都成为“四自”企业、国企上缴利润谁是收支主体、国资委要不要再设资产经营公司、国资委怎样处理上缴利润、国企创造的利润如何合理分配。

Optimal detection strategies for an established invasive pest

We model optimal detection of sub-populations of invasive species that establish ahead of an advancing front. For many invaders, eradication of the main population is an untenable goal, yet it may be possible to treat and eradicate emerging sub-populations once these sub-populations are detected. We embed a dynamically optimal post-detection management plan of sub-populations into a model of optimal detection effort determination and find that optimal detection effort depends, in part, on the distance from the main front: locations closer to the front with shorter management horizons enjoy lower reductions in overall cost from intervention. The uninfested landscape is divided into two zones, characterized by different dynamically optimal management plans: a suppression zone and an eradication zone. In the suppression zone, optimal detection effort increases with distance from the front. At the distance where the suppression zone yields to the eradication zone, optimal detection effort plateaus at its maximum level.

房地产抵押价值评估中被动高估风险的成因分析

2010年以来,中国人民银行和银监会多次提示各家商业银行关注资产泡沫上涨等原因造成的贷款系统性风险,一再收紧银根并加强对存量贷款的风险管理。本文剖析了房地产抵押贷款评估中三个关键概念的混淆,指出这是造成被动高估风险的主要成因。建议重新审视现有抵押评估技术准则,以非公开市场基准下的抵押价值代替市场价值,并更多地考虑成本法和收益法的应用,以防止上述风险在新增房地产抵押贷款中的产生和扩散。     

浙江嘉兴市“两分两换”农村土地整治模式探讨

研究目的：总结浙江省嘉兴市农村土地整治的“两分两换”模式的经验,分析问题,完善改革措施,为中国东部沿海发达地区开展农村土地整治工作提供借鉴。研究方法：用制度分析方法并结合问卷调查、咨询访谈等实证方法对“两分两换”模式的利益关系、协调机制和政策实施过程进行分析。研究结果：“两分两换”模式是中国发达地区农村土地整治的有效模式之一,具有一定的借鉴意义;但也面临现有模式不完善、财政压力大、基本农田调整等问题。研究结论：作为促进城乡统筹发展的农村土地整治重要措施,“两分两换”模式需采取科学规划、加强招商引资力度、积极培育农业龙头企业等措施解决其面临的问题。
