在全球化背景下,以地方产业网络为发展模式的区域经济,其竞争力的提升需要在全球价值链中与区域外的经济行为主体积极互动,并实现升级。在这种研究视角下,本文首先界定了价值链治理的概念,然后从理论上阐述了全球价值链治理的主要类型,以及价值链治理对地方产业网络升级的影响。并在调研的基础上,以嵌入生产者驱动型价值链的浦东集成电路(以下简称IC)地方产业网络作为研究的对象,分析了全球IDM公司的治理行为对浦东IC地方产业网络升级的影响。在此基础上笔者提出,价值链治理者——全球领先公司,对地方产业网络升级的推动或阻挡,决定于地方产业网络的升级行为是否侵犯了其核心竞争力,而不是决定于地方产业网络升级的“类型”。这一结论是对国际研究的补充和修正。  相似文献

Certification is an increasingly pervasive form of market governance through which retailers and NGOs are able to exert control over producers of primary products in order to secure their commercial and institutional interests. This paper assesses the likely outcomes of emerging certification standards intended to govern production of a new global commodity, Pangasius catfish. This evaluation focuses on Pangasius producers in Vietnam and Bangladesh, and one of the key areas which standards seek to regulate; the environment. We conclude that certification is likely to result in greater differentiation and polarisation between larger and smaller farm operators and will increasingly act to exclude of the latter from access to Western European and North American markets, and that any local environmental gains produced may be of relatively minor significance.  相似文献

The interest in supply chain networks and their analysis as complex systems is rapidly growing. The physical approach to the topic draws on the concept of heterogenous interacting agents. The interaction among agents is considered as a repeated process of orders and production. The dynamics of production in the supply chain network which we observe is nonlinear due to the random failures in processes of orders and production. We introduce an agent-based model of a supply chain network which represents in more detail the real economic environment in which firms operate. We focus on the influence of local processes on the global economic behavior of the system and study how the proposed modifications change the general properties of the model. We observe collective bankruptcies of firms, which lead to self-emerging network structures. Our results give insight into the dynamics of default processes in supply chain networks, which have important implications both for risk managers and policy makers. Based on the simulations we show that agent-based modeling is a powerful tool for optimization of supply chain networks.  相似文献

Expectations about the unfulfilled potential of aquaculture as a source of animal protein for the poor of Bangladesh are currently running high. Evidence suggests that social and economic constraints to intensification are as yet poorly understood and may constitute an important barrier to improving resource utilisation. Both public sector agencies and NGOs are currently engaged in a range of aquaculture initiatives. This paper critically surveys a selection of ongoing aquaculture research and extension programmes. It is suggested that current approaches are unlikely to benefit those with low incomes in Bangladesh, since there are problems with both the conceptualisation of the `problem of aquaculture' and the types of institutional arrangements being deployed to tackle it. The paper ends with several recommendations about future priorities in terms of the nature and style of aquaculture research.  相似文献

Agricultural productivity and farmer welfare in developing countries is constrained by a multitude of market imperfections. Value chain development (VCD) is receiving much attention as a market-based policy instrument that can potentially address multiple of these constraints simultaneously. This paper provides a conceptualization of VCD and discusses how VCD can be used as a policy instrument. As an illustration, the paper describes the VCD project “SAFAL,” which uses an integrated approach to directly intervene in aquaculture, horticulture, and dairy value chains in South-West Bangladesh. The strategy is to first identify a demand downstream in the value chain and then to identify and reduce the constraints experienced by value chain actors upstream to meet this demand. Using a matched difference-in-difference methodology, this paper estimates farm household participation in SAFAL increases farm income and shortens the hungry season.  相似文献

Bangladesh has made considerable progress against human development indicators in recent years, but malnutrition resulting from poor dietary diversity and low micronutrient intakes remains entrenched. Fish is central to the Bangladeshi diet and small fish species are an important micronutrient source. Although fish consumption per capita has increased in recent years as a result of rapid expansion of aquaculture, it is likely that consumption of fish from capture fisheries (including small indigenous species particularly rich in micronutrients), has declined. This paper evaluates data on fish consumption collected in Bangladesh by the International Food Policy Research Institute in 1996/7 and 2006/7 to assess changing patterns of fish consumption and their implications for food and nutrition security. This analysis indicates that growth of aquaculture has been positive, mitigating a sharp reduction in the quantity of fish consumed from capture fisheries and smoothing out seasonal variability in consumption. However, increased availability of fish from aquaculture may not have fully compensated for the loss of fish from capture fisheries in terms of dietary diversity, micronutrient intakes and food and nutrition security, particularly for the poorest consumers. A range of approaches are recommended to sustain and enhance the contributions capture fisheries and aquaculture make to food and nutrition security in Bangladesh  相似文献

The Sustainable Development Goals (SDGs) agenda makes achieving food security and ending malnutrition a global priority. Within this framework, the importance of fisheries in local and global food systems and its contribution to nutrition and health, particularly for the poor are overlooked and undervalued. This paper reviews current fish production and consumption from capture fisheries and aquaculture, highlights opportunities for enhancing healthy diets and outlines key multi-sectoral policy solutions. Mirroring the call for a diversification of agricultural research and investment beyond a few staple grains, it is anticipated that productivity gains for a few farmed aquatic species will not suffice. Capture fisheries and aquaculture have a complementary role to play in increasing fish availability and access, and must be promoted in ways that support measurable nutrition and health gains. This paper argues that the lack of a nutrition-sensitive policy focus on capture fisheries and aquaculture represents an untapped opportunity that must be realised for ensuring sustainable healthy diets for all.  相似文献

How are Asia's business networks responding to the growing integration of the region into the global economy? To address the question the paper identifies two distinct types of Asian business network originating in two different institutional contexts. It is argued that these original contexts have imprinted upon dominant firms' governance structures and influence their preferred networking mode. Consequently, the renewal of business networks reflects the pressures of globalization and the governance structures of the dominant organizational forms in the networks. Two types of network (global commodity chains and family business groups) are described and the global pressures for change bearing upon them outlined.  相似文献

全球价值链下地方产业集群升级模式研究   总被引:72,自引:0,他引:72  
地方产业集群沿着全球价值链往上升级,并不是一个自然而然的过程,而是在“不进则退”的激烈竞争中进行的。全球价值链片断化后.各个价值环节之间是有着严格的价值等级体系的。价值等级体系的形成一般有跳跃式和蔓延式两种空间布局模式。占据不同价值环节的地方产业集群,也由此在全球形成了严格的空间等级体系。在该等级体系中.既紧密合作又相互激烈竞争的各个层级的地方产业集群时刻演绎着升级和反升级的较量。既然各个地方产业集群之间攀登和反攀登都是在全球价值链中展开.那么就应该遵循链条本身所包含的各种竞争关系。不同的竞争和升级关系又会带来不同的经济影响。  相似文献

Efforts to unlock the genetic potential of both rice and fish, when combined with improvements in the management of rice–fish systems, can potentially increase agricultural productivity and food security in some of the poorest and most populous countries in Asia. In Bangladesh, estimates suggest that the country’s potential rice–fish production system encompasses 2–3 million hectares of land. But despite three decades of research on biophysical and technical aspects of rice–fish systems, this potential has not been fully realized due to insufficient attention given to the social, economic, and policy dimensions of rice–fish system improvement. This paper provides a characterization of the diverse and changing nature of rice–fish systems in Bangladesh to shed new light on the economic viability of different rice–fish systems and recommend policy and investment options to accelerate the development of appropriate rice–fish technologies. Data are drawn from a novel subdistrict-level survey of fishery officers, a household/enterprise survey, focus group discussions, and a meta-review of the literature on aquaculture in the country, all of which were conducted in 2010–2011. Findings indicate that concurrent rice–fish systems, alternating rice–fish systems, and collectively managed systems offer considerable potential for increasing productivity and farm incomes in Bangladesh. Findings also suggest that while innovation in these rice–fish systems is being driven by households and communities, there is need for more supportive government policies and investments to enable further innovation. Policymakers need to develop effective regulations to promote feed and fish quality and quantity, for example. More rigorous analysis of the intended and unintended impacts of these policies and investments is also necessary.  相似文献

Aquaculture continues to diversify and develop rapidly in Bangladesh. A major change has taken place in parts of Bangladesh due to the growth of floodplain aquaculture (FPA) projects. FPA involves the enclosure by the landholders of parts of the floodplain through the creation of embankments and sluice gates. The enclosed water body is stocked with fish seed and the benefits are distributed amongst those who own land in the impounded area. This study has found that FPA tends to exclude a large number of poor households and adversely affects them through the attenuation of their common property rights over the floodplains, besides skewing the distribution of benefits amongst those who directly benefit from it. They have been further marginalised in project institutions that are captured by rural elites. This paper suggests a more precautionary approach to the growth of the FPA and compensation to, or inclusion of the losers.  相似文献

Fisheries are an important source of animal protein, foreign exchange earnings and employment generation in Bangladesh. This paper examines the current status of fisheries in Bangladesh, for each of the major sub-sectors — inland open waters, inland closed waters (aquaculture), and marine fisheries. Production has been on the increase for all types of fisheries, but the productivity of rivers and estuaries is variable, there are many constraints on expansion, and it is difficult to identify significant achievements from government policy efforts. A host of factors are responsible for the under-utilisation of fishing areas, including resource limitations, poor implementation of fisheries laws, the limited spread of fish farming technology, low financial capacities and ineffective extension practices. These constraints are discussed for the three sub-sectors, and some possibilities for future improvements are suggested.  相似文献

The governance of smart city networks emerges as a new research area intersecting smart governance and public networks studies. This work aims to contribute to the literature on smart cities governance by studying councillor's governance in complex networks and on network performance. To carry out this analysis, the Spanish Network of Smart Cities (RECI), one of the first of its kind and an international reference for city networks, is reviewed as a case study, with the main objective of establishing a theory on its global innovation capacity and operations, together with the local level spurring influenced on its members. A PEST (Political, Economic, Social and Technological) analysis was carried out in order to assess the impact of the smart city network both at local, national and international level. This research was completed with a consultation carried out among some of RECI's municipalities. The analysis of the results shows how RECI can be considered an example of a well organised network with quantifiable savings for its members, capable of configuring future policies in local administration, necessarily related to efficiency, digitalization and citizen-centricity and with key topics to build the future. The study also suggests recommendations oriented to potential improvements that smart city networks could undertake.  相似文献

This study assesses the level of sophistication of livestock products in Africa by evaluating technology intensity and economic complexity of each product. Using trade data from 1995 to 2012, livestock commodity exports are classified based on technology intensity. Employing a method of reflection in computing the economic complexity of export products, we find that one fifth of African livestock commodity exports are manufactured with low technology while the rest is composed of raw materials. The results also show that the ten most complex livestock commodities represent about a third of African livestock total exports while the world level is almost double this figure. Yet African countries spend a huge share of their wealth on importing complex products. The results imply that by exporting non-complex products Africa loses nearly a third of the total value of its livestock exports. To boost the value of livestock products, African countries should exploit their untapped potential while securing the domestic market to achieve import substitution. This can be done by integrating with global value chains or developing niche markets at the regional or international markets and improving productive capabilities.  相似文献

This paper provides an overview of the implications of integrating marketing and purchasing offered by traceability. The research offers some evidence of the adoption of different traceability approaches by actors along the supply chain, illustrating the relevance of the traceability issue and how traceability can be exploited. The paper presents findings from a case analysis process of five actors in the fashion industry. This industry has experienced strong integration between industrial and retail functions and relevant changes in the organisation of production networks (global shift of production to new industrialized countries and emerging markets) which place emphasis on the traceability topic. Traceability emerges as a complex concept that concerns the sharing of information about the product and production processes along the supply chain in BTB networks up to the consumers in the final market. The issue analysed focuses on organising, with a discussion of two different uses of traceability: traceability as a tool for inter-organisational control and traceability as a tool for market power. The two approaches give rise to different implications at the individual company and business network levels. The traceability process has intraorganisational consequences in terms of contents, technologies and actors involved in its implementation. These consequences are different according to the role played by the process.  相似文献

This article focuses on the complex network of control and consent through the articulation of technology and local culture in the workplace. The dynamics of this network are embedded in the interplay of global and local markets. The article explores these dynamics by focusing on the distinctive characteristics of a Central Anatolian city, Çorum, based on a case study conducted in Turkey. We observe how globalised patterns of control and consent are reproduced through the articulation of new technologies and the conservative culture specific to this locality. During the negotiations between employers and employees, this interplay plays a significant role in the construction of work realities. The consensual control produced within the framework of conservative values leads to a consensual hegemony in the organisation of labour process.  相似文献
