This paper employs the concepts of global commodity chain and global city network, trying to link both of them to create a suitable framework that makes possible a productive chain analysis with spatial aspects. From this, the objective of this paper is to perform an initial analysis on the role of the city of Rio de Janeiro within the oil and gas production chain of South America. To accomplish it, three main aspects will be analyzed: the productive network of oil and gas in South America, the location and activities of the key agents and the flows of green and brownfield investments in oil and gas sector. This analysis will be developed applying the networks methodology, an analytical approach based on the relationships between the different agents. In order to design the networks, the A barrel full database will be used. The database A barrel full consists of data related to the different oil and gas fields in the world. They are presented in regional groups, and there is information on the operating companies of each well and contracted service providers. Then, some information about the location of the companies and their acting will be collected in other sources, e.g., their websites. Thus, due to the nature of the available data, the analysis of the productive chain employed here will focus on the upstream stage. Another aspect analyzed will be the investment flows. For this purpose, data will be collected from the FDI Markets and Zephyr database, from 2007 to 2015. This data will be summarized in tables. With both approaches (networks and tables), it will be possible to have an initial idea about how important is Rio de Janeiro in the South American oil and gas chain and what is the influence of the city in the region. The results obtained so far suggest that the city is an important center for services and a FDI attractor. However, its influence appears to be small in the region and more concentrated in the national sphere.

This paper explores the strengths of intersectoral and interregional linkages of the optical sector in the frame of European strategy for smart specialization. The European Optician2020 project seeks the creation of a production model based on the creation of personalized spectacles through local manufacturing, meeting all the criteria for the smart specialization strategy: smart, sustainable and inclusive growth, thus providing a reference for a case study. In order to ascertain to what extend the promotion of the sector can benefit economic growth, an economic model is constructed using an interregional input-output database for the Spanish economy, and the quantification of linkages is made with input-output techniques to highlight the different role that the industry plays in different regions and to examiner the nature and strength of its sectoral interdependencies. Complementary analysis examines the degree of clustering in this sector. Finally an overall assessment of the sector’s role will be provided focusing on indicators such as employment, income and production.

Port wine is one of the most emblematic Portuguese products. It is mainly destined to external markets, exports representing 82% of total sales. The specific production of Port wine must include grapes exclusively harvested in vineyards located in the interior North of Portugal – a region that broadly corresponds to the NUTS III “Douro”. In the 18th century, when its internationalization begun, a significant part of the productive process was allocated to near the Oporto city – NUTS III “Greater Oporto” – where the wine was stored and aged in barrels located in cellars. Recent legislation, combined with the increasing incorporation of services inputs and modern technologies, has increased the complexity of this product value chain.

This work aims to detail the Port wine production value chain in the context of the Portuguese economy. A Multi Regional Input-Output model, considering three regions - Douro, Greater Oporto and the Rest of the Country - is used in the estimation process. Moreover, this model benefits from the independent disaggregation of six different wine products, as well as other relevant inputs used in the production of Port wine. The model also distinguishes the production technologies of “Ordinary and Sparkling Wine” and “Liquor Wine” industries. The derived framework is based on a ‘rectangular’ Supply and Use table for 2010.

The preliminary results show that in spite of being mainly an exported product, Port wine also has a high incorporation of imported inputs (25.1% of the total national value; 9.7% are imports of the Port wine industry itself, including glass bottles, distilled alcoholic products, barrels and others). In regional terms, this work concludes by an important concentration of the value chain in the region where the product is stored, aged and then sold, thought the contribution of the Rest of the Country region is also important.
