渤海古国旅游文化开发的基点与难点分析

黑龙江省牡丹江市宁安渤海镇有一处遗址——上京龙泉府遗址。它是我国唐朝时靺鞨人大祚荣建立的渤海国的都城,历经200多年的兴旺与繁荣,后被契丹人耶律阿保机所灭。契丹人不仅焚毁了当时仅次于唐都长安位列第二的大都市,连文字也没有留下。渤海国象海市蜃楼般突然出现又突然消失,一些史学家称之为"迷踪王国"。     

科技金融投入、高新技术产业发展与产业结构优化——基于省际面板数据PVAR 模型的实证研究

高新技术产业发展是推进地区产业结构优化调整的中坚力量,而高新技术产业的发展也离不开科技金融的有力支撑。本文基于科技金融投入、高新技术产业发展,以及地区产业结构优化三者间的作用机理和传导路径,利用我国30 省2007~2015 年均衡面板数据建立向量自回归模型,实证分析它们之间的动态关系。研究发现,整体来看,变量之间存在单向作用关系,即科技金融投入的增加有助于高新技术产业的发展,进而使产业结构得以优化。但分地区来看,各种原因导致上述作用路径均未能切实到达顶端。基于此,文章最后提出若干对策建议以最大限度地调动三者的动态关联作用。

Organizing a precarious black box: An actor‐network account of the Atlantic Schools of Business, 1980–2006

There is a growing use of actor‐network theory (ANT) throughout management and organization studies. While earlier ANT research used ethnography to “follow the actors” in the production of organization/knowledge, more recent studies use archival sources to examine developments over time. We extend the latter approach using qualitative social network analysis (SNA) and apply this to a case study of the Atlantic Schools of Business (ASB). Our contribution is two‐fold: first, through an examination of actors in the ASB networking processes over 26 years, we demonstrate how the seemingly stable surface of an organization can hide the precariousness of organizing; second, we reveal the potential fusion of ANT with SNA as a method for dealing with large qualitative datasets over long periods of time.

Tourism's regional development impacts : A comparative analysis of the Greek islands

This paper explores the conditions that determine tourism development and theorizes how these conditions lead to a variety of impacts on host communities. Thirty-eight Greek islands were statistically analyzed using secondary data and a smaller sample was studied in greater detail through a comparative case-study approach. While the quantity of tourism development was found to be subject to demand, its quality and integration with other sectors were associated with the size of the community. Tourism impacts were found to be beneficial in larger islands. In smaller islands with high tourist activity, while a reverse in declining demographic patterns has been observed, tourism was found to create unstable, short-term, and dualistic development. The paper concludes that factors such as the local institutional capacity to absorb development and the potential interaction of locals and tourists should be considered in the making of tourism policy.     

Tourism and economic diversification in Hong Kong

Input-output techniques are used to assess the role of tourism in the economic diversification in Hong Kong. It is found that, in comparison with domestic manufacturing, the value-added content and labor productivity of tourism are relatively high, and tourism requires very little energy, not many laborers, moderate amounts of capital and appreciable amounts of skills, all of which are ideal in an environment of rocketing energy costs, rising wages, and fast growth with rapid accumulation of capital and skills. Moreover, the shares of tourism in GDP and total employment have been increasing due to decreasing leakage. On the demand side, the growth of tourist exports is more stable than many major commodity exports partly because tourism is less subject to import protectionism. Tourism is thus considered a prime choice in the current economic diversification of Hong Kong.
