<正>无人岛即无居民海岛。按照规定,国家重大建设、国防建设、海洋权益维护、公益事业、政府投资非经营性公用基础设施和民生保障等项目用岛,以申请审批方式出让无居民海岛使用权。旅游、交通、工业、渔业等经营性海岛,采取招标、拍卖、挂牌方式出让无居民海岛使用权。未来,招标、拍卖、挂牌将成为无居民海岛市场化最主要的方式,目前,广东海洋主管部门正加快推进无居民海岛管理办法的出台。 相似文献

<海域使用管理法>建立了海域使用权制度.本文对当前海域使用权制度的设计特点进行了分析,指出,海域使用权主要是通过行政许可的方式取得,其类型多样,种类各异.目前,我国海域使用权制度主要是由具有公法性质的海域使用管理法来规范的,海域使用权制度还需要进一步完善. 相似文献

海洋渔业资源资产的产权制度不仅是决定海洋渔业资源资产利用效率的最主要因素,其本身也存在着一个价值评判的问题,产权制度的安排或产权结构的改变,都影响着资源配置的效率。或者可以这样理解,产权也是一种生产要素,在其他生产要素既定的情况下,对产权的不同配置方式将导致整个资源配置效率的不同,一定的产权制度安排决定着一定的资源配置效率。因而研究其产权变动规律,产权的运行效率尤其重要。 相似文献

赤潮是影响海洋劳动者收入最经常、最直接的因素,赤潮直接或间接地影响海洋劳动者的就业和收入水平,涉及的数额很大,范围很广,主要表现在海洋赤潮通过赤潮水体和赤潮生物毒素经由海洋各产业影响海洋劳动者收入。文章基于海产品市场、海产品经营者市场和海产品消费者市场,将赤潮与海洋劳动者收入的关系通过经济学分析细节化、系统化和全面化地展现出来,为研究作好整体的铺垫。 相似文献

There is strong interest in culturing live marine baitfish for anglers. However, there is scant information about saltwater anglers’ perception of cultured baitfish. Thus, a survey was developed and administered to assess recreational saltwater angler’s preferences for baitfish, their attitudes towards cultured baitfish, supply and demand, and specific information about pinfish (Lagodon rhomboides) and pigfish (Orthopristis chrysoptera). An online survey invitation was e-mailed to 227,829 licensed marine recreational anglers in Florida. A total of 14,871 respondents completed some portion of the survey (6.5% response rate). Inshore destinations were the most common fishing trips taken. Live bait was caught by 57.8% of respondents, purchased by 32.1%, and 10.1% did not use live bait. Perceptions of aquaculture as a means of producing bait were 43.8% positive, 20.6% somewhat positive, and 31% unknown. Consistent availability and price were identified by anglers as the two most important characteristics for an aquaculture produced marine baitfish. 相似文献

水资源产权的不同制度安排意味着不同的水资源分配机制。对于不可交易的限量水权制度,水资源主要采取计划(行政)分配机制或基于使用者的分配机制;而可交易的水权制度,主要采取市场分配机制。本文从成本、可行性、适应性、成本与收益的分配及有效性五个方面对这些不同产权安排下的分配机制进行比较,认为每种分配机制在特定的水权制度安排下都有各自的优势与弱点,没有一种分配机制适合于任何情形。对特定分配机制的选择取决于不同的制度环境及水资源的分配目标。 相似文献

The market for marine ornamentals encompasses all live marine species (fish and invertebrates) destined for the aquarium trade. In 1998, U.S. imports and exports were valued at approximately US $1.5 billion at the border (all dollar values cited in this paper are $US). In Florida, cultured freshwater and collected saltwater species accounted for $70 million and $4 million, respectively, in annual dockside revenue. To help explain Florida's marine landings and provide suggestions for future resource management and market campaigns that reflect the perceptions of the industry, a survey of wholesalers was initiated in 1999. Preliminary results indicate that there are several intermediate wholesale markets. Florida firms are closer to the supply as many also collect. Wholesalers in other states handle more freshwater product, are larger, and tend to import a larger share of their inventory. Consolidation is expected to continue, but niche markets for eco-friendly firms are expected to grow. In Florida, marketing strategies should focus on the observed higher survival rates and increasing supply of the popular invertebrate species. Many wholesalers are concerned about additional regulations that could reduce the number of collectors and thereby increase supply variability, a noted weakness of the Florida industry. 相似文献

This paper presents the findings of a study aimed at identifying the determinants of price formation in the mussel industry in the Netherlands. The Netherlands is one of the major producers of mussels in Europe and the largest exporter. As such it is expected to have an important influence on price formation in Europe. The investigation of price formation attempted to identify the most important determinants of price at the wholesale market level and to test any interactions between the Dutch market and other markets in Europe. Estimation was by means of an econometric demand analysis using monthly data from the single auction market at Yerseke. The Dutch market was found to be highly competitive, with price highly responsive to supply, quality and seasonality. This short-term price elasticity is paired with price-inelastic short-term supply. Therefore there is potential for shifting the demand curve without inducing a shift in supply. The implications of these results are discussed and suggestions for marketing put forward. 相似文献

我国海洋产业市场绩效评价及改进研究——基于Rabah Amir模型、SCP范式的解释 总被引:1,自引:0,他引:1
文章在国内外学者研究的基础上,基于Rabah Amir模型、SCP范式,建立了由海洋市场结构以及规模经济决定的海洋产业市场绩效模型。并且认为海洋产业绩效评价准则应通过资源配置效率、技术效率以及企业的规模及状况等方面来分析,同时在海洋产业的发展总体状况、产业发展特点、产业结构以及技术进步贡献率方面作了一定的实证统计分析。最后提出了推进技术创新、进一步优化海洋产业结构、破除市场壁垒等提升海洋产业运行绩效的建议。 相似文献

根据室内流水实验法,定量研究了黄、渤海生态系统7种鱼类能量收支组分,并建立了相应的生物能量学模式。7种海洋鱼类的生物能量学模式豆著不同,并可分为3类:(1)较低代谢和较高生长,如黑鲳、矛尾鳃虎鱼;(2)较高代谢和较低生长,如欧氏六线鱼和黑鲷;(3)代谢和生长均处于中等水平,如真鲷、红鳍东方纯和鲐。其差异原因可能与这7种海洋鱼类的生态习性不同相关。与淡水肉食性鱼类比较,7种海洋鱼类的代谢能明显偏高,表明海洋鱼类属于高代谢消耗、低生长效率型鱼类。 相似文献
