改革与完善中国促进节能的税收政策

通过对中国能源税收政策的分析，阐述了中国现行税收政策在促进节能方面存的不足。根据国家节约能源法的原则要求，提出了运用税收政策调整能源价格、完善现有能源税收优惠政策、增强现有税种的能源保护功能以及开征有利于节约能源的限制性税种等一系列的政策建议。     

中国能源教育发展的现状、问题与对策

从20世纪70年代以来,国际能源教育发展方兴未艾。随着经济的迅速发展和社会消费转型,中国的能源问题日益突出。建设节约型社会需要加强能源节约,需要借鉴国际社会应对能源问题的经验,大力加强能源教育。中国的能源教育发展起步较晚,虽然取得了一些成绩,但能源教育深入发展既缺乏立法保障,又缺乏平台支撑。中国能源教育发展的现状、问题需要加强能源教育的国际比较研究,尽快构建中国能源教育发展的支撑体系。     

Food Prices,Government Subsidies and Fiscal Balances in South Mediterranean Countries

Soaring food and energy prices sparked the revolts in Northern African countries at the end of 2010. This article investigates empirically the impact of world food prices on inflation and government subsidies for Algeria, Egypt, Israel, Jordan, Lebanon, Morocco, the occupied Palestinian territories and Tunisia during the ten‐year period 2002–11. Its findings reveal an asymmetry in the response of consumer‐price inflation to shocks in world food prices that made inflation rise fast while nominal rigidities prevented it from falling. Moreover, it shows that government balances deteriorated to 2% of GDP in 2008 and 2011 owing to the incremental government food subsidies, while they hardly improved in value terms when world prices fell sharply in 2009.     

基于因子分析法的节能减排对策分析

节能减排作为我国“十一五”规划的一项重要任务和国策,越来越受到国家的重视。根据多元统计分析方法,运用社会经济统计软件SPSS 17.0,以辽宁省为例对12个城市2010年的各项指标进行因子分析,并根据各城市的综合得分对其节能减排现状进行评估分析。在此基础上,根据分析结果提出设立专项资金、加强领导、发展循环经济、建立创新循环模式等具有针对性的节能减排对策与建议。     

The Moran coefficient for non-normal data

This paper summarizes findings that extend statistical distribution properties of the Moran coefficient index measuring spatial autocorrelation to non-normal random variables. Pitman–Koopmans theorem results are extended for the mean and the variance of this index. This summary includes a corollary to this theorem, as well as a new theorem (with its proof) and two conjectures implied by it. The first of these statements is supported by asymptotic heuristics; the second is supported by simulation experiment results. Mixture random variables that include heteroscedasticity or overdispersion also are explored. In addition, a simple asymptotic variance for the Moran coefficient is presented, assessed, and found to be very precise for sample sizes as small as 25–100. The principal conclusion is that independence and sample size are the most relevant properties for Pitman–Koopmans theorem results to be extended to non-normal random variables. The independent and identically distributed property reduces the necessary sample size for this extension, as do the properties of symmetry and normal approximation.     

中国能源统计工作面临的问题及发展方向

能源统计工作虽然经过几次变革,但在有效反映能源经济现象实质、为国家宏观调控和制定能源政策等提供依据方面仍相对滞后.中国的能源统计在统计方法、统计范围、评价指标体系、统计报表和统计力量、统计数据等方面都不能适应现行低碳环保型可持续发展经济模式.中国可以从能源量、能源效率、能源结构的统计以及能源清洁生产和消耗的相关统计等方面加强能源统计的研究和管理.     

农村生物质能源产业发展机遇与合理开发利用

生物质能源产业是以农林废弃物和利用边际性土地种植的生物质为原料，进行生物质能和生物基产品生产的一门新兴产业，是一种从原料到产品均非传统的农产品生产与加工。生物质能源产业的出现，为农民开辟了一个新的增收渠道，为我国新农村建设提供了一个良好的发展机遇。近年来全球生物质能源产业的快速发展和不合理开发利用造成了2008年粮食价格的暴涨，这已引起各国政府的高度关注。因此，在保障粮食安全的前提下，应当重新审视合理开发和利用生物质能源的问题。     

Fluid flow pattern analysis in a trough region: a nonparametric approach

This paper aims at identifying statistically different circulation patterns characterising fluid flow in the trough region between two adjacent asymmetric waveforms, using the velocity data collected by 3D acoustic Doppler velocimeter. Statistical clustering has been performed using ideas originating from information theory and scale space theory in computer vision for splitting the trough region into different spatially connected segments (identifying the circulation bubble in the process) on the basis of circulation patterns. The paper attempts to visualise the fluid fluctuations in the trough region, with emphasis on the circulation region, by simulating the directional fluctuations of fluid particles from the kernel density estimates learned from the experimental data. The image representation of the estimate of the spatial turbulent kinetic energy (TKE) function reveals interesting features corresponding to the regions of high TKE, suggesting the possibilities for further research in this area along the lines of feature extraction and image analysis.

中国在阿联酋的投资机会与风险分析

为促进中国对阿联酋投资、共建“一带一路”和推进中阿友好关系的持续加强，详细分析中国与阿联酋在投资领域的发展现状，从中阿两国产业合作的角度，发掘中阿未来可能存在的投资合作机会，并探析中国企业在阿联酋投资中存在的政治风险、经济风险和安全风险。研究认为，中国企业在阿联酋的能源产业、通讯产业、服装纺织产业、汽车产业、建材产业等领域存在较大投资机会，应该紧跟阿联酋国家发展战略，增加对非油气产业的投资合作，积极进行品牌营销，提升企业市场竞争力，同时注重团结协作。在投资风险方面，阿联酋政权稳固，社会稳定，政治风险较低；但在经济风险方面，阿联酋经济外向特征明显，对外依赖性强，易受外来风险影响；且阿联酋国内安全风险较低，面临巨大的地区安全压力和恐怖主义威胁，这些风险需要中国企业重视。
