灾害的逻辑

近期,联合国针对全球儿童的生存状况发表了一份报告,报告中详细阐述了在气候变化不断对人类产生影响的情况下,儿童,特别是贫困儿童的艰难处境。报告称,目前,全球已有数百万最为贫困的儿童成为了气候变化的主要受害者。因此,联合国呼吁国际社会立即对此采取紧急行动。     

好消息：科学家在南极附近发现近300种新物种

科学家在南极附近海域水面下2000米处发现7274种新物种，包括珊瑚、海星、海绵、虾、蟹。澳大利亚联邦科学与工业研究组织（CSIRO）的首席科学家尼克·巴克斯说：“对于深海，我们仍知之甚少。在水下发现如此多的珊瑚，以及如此庞大的生物群落，是一件让人非常振奋的事。”     

Shift-share Analysis on International Tourism Competitiveness - A Case of Jiangsu Province

Shift-share analysis has been confirmed a useful approach in the study of regional economics and many kinds of extended shift-share models have been advanced and put into practice in economic studies, but few have hitherto been introduced and applied to the tourism research in China. Moreover understanding the spatially competitive relationship is of paramount importance for marketers, developers, and planners involved in tourism strategy development. Based on international tourism receipts from 1995 to 2004, this study aims at probing into the spatial competitiveness of interna- tional tourism in Jiangsu Province in comparison with its neighbors by applying a spatially extended shift-share model and a modified dynamic shift-share model. The empirical results illustrate that exceptional years may exist in the ap- plication of dynamic shift-share models. To solve this issue, modifications to dynamic shift-share model are put forward. The analytical results are not only presented but also explained by the comparison of background conditions of tourism development between Jiangsu and its key competitors. The conclusions can be drawn that the growth of international tourism receipts in Jiangsu mainly attributes to the national component and the competitive component and Zhejiang is the most important rival to Jiangsu during the period of 1995-2004. In order to upgrade the tourism competitiveness, it is indispensable for Jiangsu to take proper positioning, promoting and marketing strategies and to cooperate and integrate with its main rivals.     

国际极地年中的IGBP项目
