In this paper, we analyze the compettve and innovatve trajectories followed by the canned fsh industry in recent tmes. We base our study on four case studies from the Galician industry in Spain, which comprises the largest share of the European canned fsh sector. At least four different innovaton paterns are found in the industry. The frst patern is a conservatve one where innovaton is seen as a risk and therefore maintaining current routnes is the chosen opton. The second patern has been defned as “large retailer-dominated” and is followed by companies that have signed exclusive agreements with large retailers, which increasingly determine most of their innovaton actvites. The third strategy we have defned as “territory-orientated,” since product innovaton and incorporaton of quality distnctons based on the territory are the main innovaton drivers. Finally, we have an “ecological or natureorientated” innovaton strategy where meetng ecological normatve requirements is the main innovaton driver.
本文分析了近年来鱼罐头行业的竞争和创新轨迹。我们的研究基于西班牙加利西亚工业的四个案例研究,该行业占欧洲罐头鱼行业的最大份额。该行业至少有四种不同的创新模式。第一种模式是保守的,创新被视为一种风险,因此保持当前的路线是选择。第二种模式被定义为“大型零售商主导”,其次是与大型零售商签署排他性协议的公司,这些公司越来越多地决定了它们的大多数创新活动。第三个战略我们定义为“地域导向”,因为基于地域的产品创新和质量差异是主要的创新驱动因素。最后,我们有一个“生态或自然导向”的创新战略,满足生态规范要求是主要的创新驱动力。

Tuna Fisheries and Trade within COMESA 东南非共同市场内的金枪鱼渔业和贸易

Tuna is an important marine resource caught in most oceans. Certain tuna species in some of the existing stocks are already overfished, while others are fully exploited. Various mechanisms such as those stemming from the UNCLOS are in place and efforts to streamline management of the tuna fishery are ongoing. Within the Western Indian Ocean (WIO) where the tuna stock is reported as moderately exploited, fishing fleets of Distant Water Fishing Nations (DWFN) are active. Here, they have deployed better technology, catching and trading more tuna than countries operating a less technical operation. Many of the COMESA members operating in this fishery can be described as having a less technical operation. As a consequence, some COMESA countries operating within the same fishery have little or no exports reported in their trading books. This is despite tuna being among the leading tradable marine fish, representing 8% of the value of internationally traded fish products. This paper first reviews relevant literature relating to the tuna fishery within the WIO region. Next, the paper employs an augmented gravity model in an attempt to determine whether membership in COMESA is likely to imply more internal tuna trade. Data on the export of unprocessed tuna (fresh, chilled and frozen) from various data portals is used for this purpose. The study period considered stretches from 2001 to 2012 and examines exports from 19 countries operating in the WIO. Like the bulk of gravity models in trade literature, our approach employs a number of estimation approaches including the Poisson Pseudo-Maximum Likelihood Estimator as well as the usual OLS. Results show no evidence that COMESA membership means improvements in tuna exports. The analysis suggests several areas that COMESA may take to improve trade among members operating in the WIO tuna fishery. Among them include suggestions for increased investment from locals in the fishery. In addition, suggestions are provided on agreements between fisheries authorities and trade partners, recommendations which may strengthen the bargaining position of COMESA countries and introduce economically viable management decisions and consequently, better trade outcomes.
金枪鱼是大多数海洋捕捞的重要海洋资源。一些现有种群中的某些金枪鱼品种已经被过度捕捞,而另一些品种则被充分利用。《联合国海洋法公约》等各种机制已经到位,精简金枪鱼渔业管理的努力正在进行中。在金枪鱼资源被报告为适度开发的西印度洋(WIO)内,远洋捕鱼国(DWFN)的捕鱼船队十分活跃。在这里,他们采用了更好的技术,比那些技术含量较低的国家捕捞和交易了更多的金枪鱼。从事这一渔业的东南非共同市场的许多成员可以说是技术水平较低。因此,在同一渔业内经营的一些东南非共同市场国家的贸易账簿上很少或根本没有出口报告。尽管金枪鱼是主要的可贸易海鱼之一,占国际贸易鱼类产品价值的8%。本文首先回顾了有关世界渔业组织区域内金枪鱼渔业的相关文献。接下来,本文采用了一个增强的重力模型,试图确定东南非共同市场的成员资格是否可能意味着更多的内部金枪鱼贸易。为此目的使用了来自各种数据门户的关于未加工金枪鱼(新鲜、冷藏和冷冻)出口的数据。研究期间从2001年到2012年,调查了在世界贸易组织开展业务的19个国家的出口情况。与贸易文献中的大部分重力模型一样,我们的方法采用了许多估计方法,包括泊松伪极大似然估计器以及通常的OLS。结果显示,没有证据表明东南非共同市场的成员资格意味着金枪鱼出口的改善。分析提出了东南非共同市场可以采取的几个领域,以改善从事世界渔业组织金枪鱼渔业的成员之间的贸易。其中包括增加当地人对渔业投资的建议。此外,还就渔业当局与贸易伙伴之间的协定提出了建议,这些建议可以加强东南非共同市场国家的谈判地位,提出经济上可行的管理决定,从而取得更好的贸易成果。
