粤港澳大湾区旅游竞争力与城市化的耦合协调度及其对地方经济的影响

研究旅游竞争力与城市化的耦合协调效应对地方经济的影响具有重要意义。以粤港澳大湾区为例,利用2007—2019年的时间序列数据,构建旅游竞争力—城市化的耦合协调度评价模型,通过固定效应模型检验耦合协调度与地方经济之间的因果关系,最后利用VAR模型作进一步分析。研究发现：（1）粤港澳大湾区旅游竞争力和城市化的耦合协调度在波动中上升,不同地区波动时点和波幅存在差异;（2）地方经济增长和耦合协调度间呈现正相关,在时间序列上存在长期稳定关系;（3）广州、东莞、江门和澳门的耦合协调度对地方经济产生显著的冲击效应与方差贡献,其中广州和澳门的响应积极迅速,东莞存在滞后性,江门波动较大。研究结果对建成“宜居宜业宜游”湾区具有一定参考价值。     

国际河流管理合作模式的分类及演进规律探讨

论文对国际河流管理合作模式的概念、分类及演进规律进行了探讨。在从合作主体、目标、途径、制度等方面对合作模式进行单维度分类的基础上,借鉴霍尔三维结构图系统分析方法,构建了合作模式三维度分类模型,较全面、准确地概括了当前国际河流管理合作实践的模式类型。最后,综合世界各种典型国际河流管理合作模式的形成和发展过程,从模式要素的发展演变及模式演进的动力机制两个方面入手,详细阐述了国际河流管理合作模式的演进规律。     

Fish as an indicator of aquatic environment: Multielemental neutron activation analysis of nutrient and pollutant elements in fish from Indian coastal areas

Fish is the main food in coastal areas and its analysis for toxic metals has been used as an indicator of the pollution status of the aquatic environment. Several different fish species from the three Indian coasts, Visakhapatnam in the east, Mumbai in the west and Mangalore in the south west and also inland freshwater fish from Nagpur in the central region for comparison were analyzed for up to 20 elements (As, Au, Ba, Br, Cl, Co, Cr, Cu, Fe, Hg, K, Mn, Na, P, Rb, Sb, Sc, Se, Sr, Zn) by instrumental neutron activation analysis (INAA). Dried fish samples in powdered form were irradiated with thermal neutrons in a nuclear reactor followed by high resolution gamma ray spectrometry at different intervals. Several Reference Materials (RMs) of biological origin were analyzed for quality assurance and data validation. Elemental contents in different fish species vary in a wide range depending on the species, its size, location, and aquatic environment. Fish from Mangalore showed highest mean contents of Cr (14.8?±?29.9?µg?g^?1), Cu (1005?±?643?µg?g^?1) and Sb (849?±?888?ng?g^?1) whereas those from Mumbai exhibited highest Hg (2066?±?2146?ng?g^?1) and P (20.3?±?4.63?µg?g^?1) but lowest Cu (6.30?±?3.10?µg?g^?1) contents. Fish from all the regions showed significant amounts of nutrient elements such as Na, K, P, Mn, Fe, Se and Zn as well as some pollutant elements (Br, Cr, Sb, Hg). No regularity in variation of elemental contents with the size was observed. Prawn (Panaeus latisulcatus), a popular fish species from four different regions showed wide variation in elemental contents of Cr, Mn, Fe, Zn, Se, P including toxic pollutants, Sb and Hg. An attempt has been made to calculate daily dietary intake (DDI) for some nutrient elements from Indian fish. Elemental data for Cr, Cu, Fe, Hg, Se, and Zn have been compared with those from other fish exporting countries.     

The greener,the more cost efficient? An empirical study of international tourist hotels in Taiwan

Going ‘green’ is more than a mere fad in the hotel industry, and environment-friendly green hotels are becoming popular. The purpose of this study was to conduct an investigation into the link between ‘green’ and cost efficiency in the hotel industry. Empirical evidence supporting this investigation was gathered from the Taiwan hotel industry. Data were gathered from 68 international tourist hotels in Taiwan. Moreover, our finding differs from most of the earlier studies and indicates that ‘green’ is negatively and significantly associated with the cost efficiency of a hotel. In other words, ‘green’ renders a hotel ineffective. The implications of the findings have been discussed, and the limitations of the study as well as future research directions have been addressed.     

国际河流管理和内河流域管理比较研究

传统来看,国际河流和内河在管理模式、政策、法规上从来都是各自为政的。然而,利益主体的多元性,河流自身生态系统的统一性都说明了这两种河流的管理,包括合理利用和有效保护,具有共通之处,因此,成功的国际河流管理经验可以内河的利用保护所借鉴。在将国际河流保护制度和内河管理制度惊醒比较之后,本文试图从对比中思考我国内河流域管理立法模式、流域管理机构的地位和如何协调流域内部利益。流域管理不应单独立法,流域管理机构的地位在新《水法》中有所明确,但其职责还需进一步向统一宏观规划调度的方向定位,由流域管理机构根据公平合理地原则进行流域内部利益协调。只有将流域管理机构和协调流域内部利益紧密结合起来,才是流域可持续发展的关键。

西南国际河流水资源状态及开发中的问题

西南国际河流流域地形复杂、海拔高、人口稀少,人均水资源量丰富,出境水量大,水质好,目前开发利用程度低,具有广阔的开发利用前景。但随着我国加入WTO,经济和社会发展融入国际的步伐加快,对国际河流的开发和利用也必然要按照国际法或国际惯例。首先对西南国际河流水资源的自然状态,我国在各自流域中的地位、开发利用状态以及存在的问题进行了论述;然后讨论国际河流开发中应注意的问题和准则;最后,根据可持续发展的原则和各个河流的特点,提出建议：应该充分认识到我国西南国际河流地区生态环境脆弱和社会经济发展水平较低的状态,今后应以水资源保护为主,优先发展航运和旅游业,合理开发水能资源。同时应积极参与国际合作与交流,与相关国家共同开发流域水资源,促进流域经济社会的可持续发展。     

The livelihoods gap: responding to the economic dynamics of vulnerability in Somalia

A 'livelihoods gap' has become evident in international aid delivery to Somalia. Existing aid interventions do not address the economic dynamics of vulnerability resulting from Somalia's long history of predatory development and asset stripping. To prevent poor households' regular return to sub-subsistence income levels after a brief period of plenty, this paper argues that aid agencies should reorient and expand existing interventions to assist poor households to capitalise on temporary improvements in environmental and security conditions. As a corollary to emergency relief and efforts to construct state institutions, it is necessary to devise country-wide interventions that will rebuild household asset bases by protecting savings during times of stress and ensuring that markets benefit poor producers.
