以政府职能转变推动收入分配改革

收入和财富分配的不平等一直是中国改革发展中的重要问题。针对中国经济的特点,可以从政府改革的角度来研究如何更好地进行收入分配改革。地方政府主导推动地方经济的做法对收入不平等的扩大起了重要作用,加快政府职能转换,是使收入分配改革真正落到实处的破局之处,也是实现收入分配合理化可行的第一步。要改变地方政府的经济职能,降低它直接参与基础设施的程度,改革地方土地财政,建立垂直管理机构,以分散它的一部分经济管理职能,为收入分配改革打开空间。

多层微波集成电路中微带线层间互连仿真

针对多层微波集成电路设计的微带线层间互连问题，介绍了垂直通孔互连、垂直带条互连和层耦合过渡互连三种高性能的互连方法，并且采用三维电磁仿真软件HFSS对这三种互连结构进行了建模和仿真。仿真结果表明，垂直通孔互连和垂直带条互连在0.1～25 GHz的频宽范围内，回波损耗S11<-20 dB，插入损耗S21>-1 dB，互连性能优良，而层耦合过渡互连在20～68 GHz内回波损耗S11 <-20 dB，插入损耗S21>-1 dB，具有在毫米波频段实现互连的潜力。     

Probabilistic assessment of fleet-level noise impacts of projected technology improvements

Demand projections for civil aviation have forecast increases in operations in future decades. Increases in demand are beneficial to the growth and advancement of the aviation industry, but also come with the threat of significant increase in environmental impacts. In response, the industry is focusing on programs to develop technologies for reductions in fuel burn, NO_x emissions, and noise. While aircraft-level impacts are an obvious metric of success, it is difficult to make informed robust technology investment decisions with respect to noise without understanding the fleet-level impacts. Fleet-level predictions of noise for technology explorations are especially complicated because it is computationally expensive, highly combinatorial, and airport-specific. Recently, rapid automated airport noise models have been developed, which can be simulated using Design of Experiments (DOE). The results of these simulations are used to generate surrogate models for airport noise contour area, which can be summed to yield a fleet-level impact. These models make use of simplifying assumptions to provide estimates of airport-level noise that are substantially cheaper to compute. They can be used to perform parametric trade-off analyses in conjunction with the equivalency assumption. Equivalency asserts that environmental impacts of a technology infused aircraft can be represented by scaled operations of the baseline aircraft in the same class. This simple assumption allows for the modeling of technology and market penetration factors under the same units: operations. This research uses surrogate models in conjunction with the equivalency assumption to examine two potential technology scenarios in a target forecast year, simulating technology and market performance factors to identify vehicle classes that could have the greatest impact in reducing contour area. Results show that technology and market performance of future notional Small Single Aisle and Large Single Aisle vehicle aircraft have the highest positive correlations with potential reductions in contour area.     

Flight-to-quality and correlation between currency and stock returns

We document that capital flows in and out of emerging or developed markets are sensitive to global equity market conditions. Capital tends to move out of emerging into developed countries in global down markets, leading to depreciation (appreciation) of emerging (developed) currencies. This generates a positive (negative) correlation between currency and equity in emerging (developed) markets which is amplified by the magnitude of the capital movement. We also verify that hedging currency risks may undo the natural hedge and increase the total return volatility under negative correlation.

闽台旅游合作研究进展

海峡两岸闽台之间的＂五缘＂优势关系,使得闽台旅游合作已经成为两岸旅游业发展的重要议题。尤其是自2008年两岸直航启动后,大陆居民赴台旅游人数激增,这无疑给台湾旅游业带来了巨大的经济效益。随着两岸关系的不断发展,闽台旅游合作在旅游资源开发与整合、旅游产品的开发、旅游共同市场等多方面也有较多的合作与研究。本文在近十年来（1999—2010）闽台旅游合作研究的基础上,分析其研究的主要内容和领域,研究目前闽台旅游合作存在的问题与不足,并对其发展前景进行展望。     

社会收入对西部城乡收入差距的影响——基于11省市2000户居民的调查数据

对城乡收入差距的研究最终将关注于真实收入的差异,本文依据对西部地区11个省市的2000个镇(村)2000户居民的调查数据的统计分析,发现西部地区社会收入的差距比经济收入的差距大得多;社会收入会对城乡收入差距产生直接影响,使西部地区城乡收入比扩大10.4%。因此,建议重视缩小西部地区城乡社会收入差距的政策设计、增加西部地区农村居民的社会收入、推行城乡一体化的社会保障体系、改革收入统计。
