旅游投资增长质量对旅游业高速发展和产业转型升级至关重要。利用1999-2014年中国旅游投资省际面板数据,从产出效率与运行过程两方面,系统分析了旅游投资增长质量的时序动态变化与地区差异。结果表明:①考察期内旅游投资增长产出效率提升明显,并处于中高水平。但东中西区域差异明显,中西部旅游投资增长效率低于东部地区,具有一定阶梯性。②旅游投资增长时序波动性较明显,呈现出时冷时热的变化态势,体现出总体稳定性欠佳。东中西区域的稳定性也较差,但自2011年后有所改善。③旅游投资增长协调性不好,表现为旅游投资增长滞后于旅游发展需求。旅游产品(项目)开发与相关基础设施建设,还无法满足快速增长的旅游新需求。这为提升旅游投资质量提供了新的参考与依据。  相似文献

Our study shows that high‐speed railroads (HSR) can either polarize or diffuse economic geography based on the sector and distance between cities. Economic activities could agglomerate from distant to core areas, while disperse from core toward its periphery at the same time. Empirical evidence from the 1982 introduction of two major HSRs in Japan, which halved intercity transit time, support this. Noncore areas lost 3–6 percent population; service employment declined 7 percent, whereas manufacturing employment increased by 21 percent. Municipalities within approximately 150 km of Tokyo expanded, while the distant ones contracted. The net result is that the Tokyo metropolitan area agglomerates because of HSR.  相似文献

The paper examines the significance of state territoriality and the related multi‐scalar practices of the state in the light of the symptoms of post‐politics exemplified in global environmental governance. The focus rests on the South Korean government's Green Growth (GG) strategy and the efforts to export this strategy as a role model to emerging economies worldwide through the establishment of the Global Green Growth Institute. We begin with the question why the Korean government is going global with a political program that is heavily disputed at home. We then study the practices by which the state manages to maintain its territoriality under the conditions of global climate change. Lastly, we discuss how multi‐scalar practices of environmental governance in the GG strategy are applied by state and non‐state actors both in Korea and abroad.  相似文献

三国西晋的越窑青瓷,品质、器类、装饰皆臻于顶峰。同时,生产工艺也达到极高的水准。文章以尼姑婆山窑址为例,从龙窑与窑具、装饰、成型、修坯、上釉、烧成等多个方面,论述了越窑青瓷的生产工艺,认为装饰、模制成型工艺最能代表当时的水平。这些复杂工艺在东晋以后失传,与北人南迁破坏了当地的制瓷传统,从而导致窑业萎缩的历史背景密切相关。  相似文献

Abstract: The development economist Dani Rodrik recently declared that “the globalization consensus is dead”. The claim has momentus implications, because this consensus has steered economic policy around the world for the past quarter century. It emanates from the heartland of neoclassical economics, and defines the central tasks of the Washington‐based organizations which claim to speak for the world. This essay answers two main questions. First, is Rodrik's claim true, and by what measures of “consensus”? Second, to the extent that the consensus has substantially weakened, is the state returning to the heart of economic life, as Karl Polanyi might have predicted? The answers? First, the globalization consensus about desirable economic policy has weakened, though it is far from “dead”. Second, the western state is returning to the heart of economic life in response to the current global economic crisis, but will retreat soon after national economies recover—because unless the crisis becomes a second Great Depression, the norms of more free markets and more global economic integration will be politically challenged only at the margins. New rules of finance may be introduced, but with enough loopholes that by 2015 Wall Street and the City will operate in much the same way as in the recent pre‐crisis past.  相似文献

乾卦六龙态的天文含义研究--《左传》"龙纪"历法钩沉   总被引:2,自引:0,他引:2  
《左传》昭公四年的“龙纪”,是上古以苍龙星为历象的太阳历的记载。这个苍龙星星象在《易经》乾卦六爻爻辞中有形象的描述,根据寅月“见龙”、午月“跃龙”等记载,可知其观测年代当在夏代以前。这种借龙“以喻天之阳气”的龙纪历法流传至先秦秦汉,或称“易历”、“气历”;或称“律历”、“甲历”。它以天干记日,十日为旬,六旬为甲,六甲为岁,一岁360日;并通过不记在日序之内的56日的过年日使历年长度略等于回归年长度,从而形成了原始社会晚期一部较实用的历法。  相似文献

City officials are continuously working to attract airlines willing to fly to new destinations. The inherent expectation is that a more extensive aviation network stimulates economic growth. This paper investigates empirically the causal implication of this hypothesis. Using data on nonstop flights by origin and destination over the period 1984–2013, we propose a new measure for a metropolitan area's connectivity to the national aviation network. We then use this measure to investigate its contribution to local economic development, as captured by the growth in population, in total employment, in per-capita income, and new firm entry. To ensure causality, we use instrumental variable methods that exploit geography and destination airports growth as a way to capture the exogenous variation in the likelihood to add new travel routes. Our results suggest that a metropolitan area's air connectivity, resulting from an expansive local aviation network, has a positive effect on population, on employment and on the number of businesses established in that location.  相似文献

三种含Cu、As绿色颜料的拉曼光谱研究   总被引:1,自引:0,他引:1  
分析和确认古代颜料的成分是文物研究中的一项重要工作。为对四个来自不同地区的含Cu、As元素的绿色颜料进行鉴别,应用拉曼光谱仪并辅助以扫描电镜能谱分析仪(SEMEDX)和X射线衍射仪(XRD)进行研究。结果表明其分别为墨绿砷铜矿、氯砷钠铜石以及巴黎绿。对其来源分别进行了讨论,因巴黎绿在国内青铜修复和古建彩画当中的大量应用,过去对于含有Cu、As的绿色颜料通常鉴定为巴黎绿。墨绿砷铜矿和氯砷钠铜石为在文物彩绘中新发现的两种矿物颜料,为绿色颜料的鉴定提供了新的思路。  相似文献

Daily growth increments in fish otoliths have been demonstrated for the first time on Quaternary sagittae from a late palaeolithic site in Egypt and they have allowed us to establish the season of fishing. Transverse sections of tilapia sagittae studied under light-microscope demonstrate that recrystallization during diagenesis renders the majority of the margins unreadable. The well-preserved otoliths, however, all have widely spaced outer growth lines, indicating that the fish died during a period of fast growth which coincides with the flood season. Moreover, counting the daily increments showed that late palaeolithic man captured the animals on the floodplain of the Nile after the maximum of the flood, when residual pools were present.  相似文献

Reactive new bone on the endocranial surface of the skull in non‐adults has recently received a lot of attention in the palaeopathological literature. These features appear as layers of new bone on the original cortical surface, expanding around meningeal vessels, as isolated plaques, ‘hair‐on‐end’ extensions of the diploë or, as ‘capillary’ impressions extending into the inner lamina of the cranium. These lesions are commonly found on the occipital bone, outlining the cruciate eminence, but have also been recorded on the parietal and frontal bones, and appear to follow the areas of venous drainage. Although recognized as resulting from haemorrhage or inflammation, their precise aetiology is still a matter of controversy. This paper outlines their possible causes and examines their nature and distribution in a group of non‐adults from four archaeological sites in England. It is recommended that, when recording these lesions in the future, additional skeletal pathologies, the age of the child, and nature and distribution of the lesions also be taken into account.
