Areal differentiation of virtual water for agricultural products and its effect on regional agricultural structure adjustment in China： 1995-2007

With a vast territory, the space-time distribution of water resources is uneven in China. There is a great dif ference in natural conditions and farmland management of agricuttural production in different regions. The areal differentiation of agricultural products virtual water is obvious. Comparison with the agricultural products virtual water from 1995 to 2007 in China shows an increase in the first ten vears and a little decrease in recent years. There has been a tendency of increase all the time in Northeast and Northwest. but a decrease after an increase firstly in other regions. The virtual water offood crops is the maximum which accounts for more than 70% in China. and that of vegetables is in a fast growth. The proportion of agricultural products virtual water to the total water resources in each region has a large difference, showing the imbalance of agricultural water in different regions, which accounts for 50%-90% in Northeast, and 125%-185% in North China. Under the guidance of virtual water strategy, based on the differences of resource endowment, each region should adjust agricultural structure, decide production by water, and select water suitable crops. In water-rich region, agricultural produets of high water consumption should be planted appropriately, which will make full use of the abundant local water resources. In water-shortage region the crop production of high water consumption and low efficiency should be depressed, and that of low water consumption and high efficiency should be supported and increased. It will achieve reasonable disposition of water resources, promote ecological restoration and environmental protection, as welt as ensure food security.     

加入WTO后我国民族自治地方发展边境贸易的政策及其机制探析

边境贸易长期以来一直是民族自治地方经济发展的主要推动力之一。然而,我国民族自治地方的边境贸易总量规模小、出口商品档次低、与有关周边国家的边境贸易不平衡、贸易政策不对等。民族自治地方边境贸易发展还存在一些深层次的制约因素。目前,我国边境贸易政策与WTO有关协议存在一些不一致的地方。今后,加快发展我国民族自治地方的边境贸易,应该从边境地区实际情况出发,按照WTO规则和鼓励我国民族自治地方经济发展的要求,调整和完善现行民族自治地方边境贸易的政策与管理,进一步提高边境贸易的档次,规范贸易行为,以促进边境贸易的健康发展。     

"诗"与"生活"之间--论中国现代散文的语言个性

现代散文作为一种抒情言志的文体，总是以情动人，通过情感、情绪的感染和冲击，发挥怡情功能和审美功能，所以它的语言既有浓厚的生活气息，又有作家鲜明的个性风格和饱满的感情色彩。现代散文致力于用更准确、更形象、更优美的文字，去表现作者的思想、情感。现代散文务求语言的简练含蓄，但有时作者依据传情达意的特殊需要而有意构成语言的反复与重叠。

“单位制”城市空间的社会生产研究

作为计划经济时代政治、经济和社会体制的基石,单位制度对我国当前的社会体制转轨和社会经济转型产生了极为广泛和深刻的影响。而"单位制"城市空间生产方式构成了我国当前城市空间转型的基底,有别于理论形态的"社会主义空间生产"的规则。对"单位制"城市空间生产的研究,既是对既有城市发展路径的反思,又是对城市未来发展模式的探索,是我国城市空间转型研究的重要内容。从"空间生产"理论出发,从政治经济空间组织、计划经济资源配置方式、公有制的土地制度和重工业导向的城市经济发展路径等方面概括了"单位制"空间生产的政治经济基础,揭示出"单位制"城市空间生产方式在组织单元、政治经济功能、生产主体和功能单元、生产内容和职能、空间生产的价值倾向以及相应的空间分化形态等方面的基本特点,同时指出新的政治经济背景下,"单位制"空间生产方式的效率相对低下、城市企业主义治理下空间商品化属性凸显、空间的"使用价值"与"交换价值"悖离而导致空间冲突锐化、"空间公平"的追求的愈加重要等问题,并进而指出城市空间生产方式由封闭式的"单位制"向开放式的"社区制"转型的趋向。     

新疆新型工业化背景下外向型主导产业选择研究

新时期供给与需求的双重约束,使得新疆进入了新型工业化时期。同时随着我国对外开放程度的不断深化,新疆在中国实施向西开放战略中的地位也日益凸显出来。为了寻找外向型经济新的增长空间,促进产业结构调整与升级,加快区域新型工业化进程,必须要构筑外向型主导产业。构建了增长潜力、关联效应、对外开放度、技术进步、就业功能、可持续发展、区域比较优势七个外向型主导产业选择基准和13个量化指标。以此为基础,实证选择分析得到了新疆新型工业化背景下外向型主导产业。它们是电气机械及器材制造业,食品制造业,石油加工炼焦加工业,化学纤维制造业,纺织服装、鞋、帽制造业,化学原料及化学制品业,非金属矿物制品业七大产业。     

从澳大利亚科学国际化评估结果看科技国际化的重要性

近年,澳大利亚等许多西方国家纷纷开展科教国际化评估和研究。研究表明：世界科技重心正在向东和南转移,亚洲和南美国家的科技产出占世界的比重快速提高;澳大利亚和OECD其他国家国际合作论文的比重快速增加,国际合作论文成为论文增长的主要来源;合作发表论文的引用率明显高于本国发表论文的引用率,国际合作论文成为论文引用率提高的重要原因。由此表明：科技国际化已成为全球科技创新的重要趋势,是提高科技创新效率、增强科技竞争力和国际影响力的重要途径。     

NAIRU Estimates for Germany: New Evidence on the Inflation–Unemployment Tradeoff

Meaningful estimates of the non‐accelerating inflation rate of unemployment (NAIRU) within a Phillips curve framework require an identified tradeoff between inflation and unemployment. However, observations of inflation and unemployment are equilibrium points giving rise to a simultaneity problem. We assess conventional identifying assumptions in the literature on the German NAIRU in a general bi‐variate equations system of inflation and unemplyoment. We use a data‐driven method for identification based on shifts in the relative volatility of shocks to unemployment and inflation to identify the tradeoff for Germany. Our results support models which estimate a contemporaneous effect of unemployment on inflation and those which model inflation and unemployment jointly.     

Assessing the Degree of Spot Market Integration for U.S. Natural Gas: Evidence from Daily Price Data

This paper assesses the degree of market integration in the U.S. natural gas market following the FERC’s ‘open access’ reforms. Daily spot prices at 76 market locations from 1993 to 1997 are used to examine the geographic extent of the market and the speed with which market forces move prices toward equilibrium in the face of ongoing price shocks. The empirical results suggest that the East and Central regions form a highly integrated market, but that this market is quite segmented from the more loosely integrated Western market.
