Abstract Purpose With the availability and utilization of Inter-Country Input-Output (ICIO) tables, it is possible to construct quantitative indices to assess its impact on the Global Value Chain (GVC). For the sake of visualization, ICIO networks with tremendous low- weight edges are too dense to show the substantial structure. These redundant edges, inevitably make the network data full of noise and eventually exert negative effects on Social Network Analysis (SNA). In this case, we need a method to filter such edges and obtain a sparser network with only the meaningful connections. Design/methodology/approach In this paper, we propose two parameterless pruning algorithms from the global and local perspectives respectively, then the performance of them is examined using the ICIO table from different databases. Findings The Searching Paths (SP) method extracts the strongest association paths from the global perspective, while Filtering Edges (FE) method captures the key links according to the local weight ratio. The results show that the FE method can basically include the SP method and become the best solution for the ICIO networks. Research limitations There are still two limitations in this research. One is that the computational complexity may increase rapidly while processing the large-scale networks, so the proposed method should be further improved. The other is that much more empirical networks should be introduced to testify the scientificity and practicability of our methodology. Practical implications The network pruning methods we proposed will promote the analysis of the ICIO network, in terms of community detection, link prediction, and spatial econometrics, etc. Also, they can be applied to many other complex networks with similar characteristics. Originality/value This paper improves the existing research from two aspects, namely, considering the heterogeneity of weights and avoiding the interference of parameters. Therefore, it provides a new idea for the research of network backbone extraction.

This report uses the Global Value Chain (GVC) data framework to provide scoping review and analysis of Mexico's current position and potential for using and harvesting GVC data in the automotive and electronics sectors. By conducting the study on GVCs data, we hope to broaden the understanding of the importance of data transfers for GVCs, production, and trade, underlining that data are critical to all companies and not only to the so-called "high-tech companies." Data protection, sharing, and security are also central to manufacturers in the automotive and electronics sectors. This report will review how datafication, data protection, sharing, and security impact Mexico's automotive and electronics industry. This information is analyzed from a global perspective and the viewpoint of Mexico to provide a holistic picture of the situation when identifying trajectories for entry, growth, and upgrading along GVCs that rely on datafication and digital transformation. It will also offer recommendations for regulators and policymakers on how to facilitate successful GVCs' data functioning and guidance for businesses on how to harvest data for growth and digital transformation.

Global Value Chain (GVC) is a relatively new concept where the process to produce goods or services occurs across countries. Previous research has concluded that integrating in GVC is important for a region to promote its economic growth. One indicator of a region's involvement in GVC is its export value at which in the Province of East Java, the jewelry industry (HS code 71) is the largest export contributor. This study aims to identify new export destinations based on trade data and to analyze internal factors of strength and weakness as well as external factors of opportunity and threat to formulate strategy to improve the competitiveness of jewelry industry with small, medium and large scale in East Java. In this research, the trade balance of jewelry industry between Indonesia and East Java and global importers was analyzed. The results show that some countries in Asia and Oceania, Europe and America are potential markets for the gold industry in East Java to increase the current value of exports. The geographical location of East Java which is close enough to the current export destination countries of jewelry products (Taiwan, Japan and Singapore) as well as potential destinations (India and China) is a competitive advantage. This research also identifies several strategies that can be done by the stakeholders in developing the jewelry industry in East Java.

AbstractChina's accession to the WTO in 2001 is widely accepted as a landmark event for the multilateral trade system and for the country. The large-scale WTO-plus commitments have nevertheless received unceasing criticism and discussion. This article is concerned with the resulting policy implications for the Chinese initiative to become a global producer of large civil aircraft at the next stage of development. A real-life case study is expected to provide robust evidence for inquiring whether China and emerging economies alike can smoothly advance up the global value chain while honouring their WTO obligations in good faith. The article confirms the widespread opinion that there are vast legal uncertainties ahead for China throughout this journey, and for that reason, a rigorous market-orientation effort is needed to strengthen its ability to compete in the commercial aviation sector.

The study aimed to analyze the function mechanism for producer services to upgrade value chain based on spatial networks, with regional domestic Export Sophistication Index for measuring the position of China’s provinces in the global value chain. Using spatial econometrics model, the study set up a variety of spatial weight matrices, to empirically test the spatial networks’ effect as a result of the producer services with changes in the positions of China’s various provinces in the global value chain. Results indicate that: first, the producer services have an obvious spatial networks effect on upgrading of the various parts of China in the global value chain. Second, the estimated results of distance based spatial weights matrix model were contiguity based spatial weights matrix results, implying that space network effect is not limited to the neighboring provinces. Third, the spatial network effect of economic based weights matrix model was stronger than distance based spatial weights matrix model, which shows that today, the changing value chain of Chinese provinces is more inclined to “regional powerful combination”, rather than “regional strength complementary”.

Although North Korea is one of the most closed countries in the world, it has long been pursuing international cooperation with other countries in order to upgrade the quality of its film industry to international standards. Preceding studies on this topic have mainly focused on the political influences behind filmmaking in general and very few studies have exclusively dealt with North Korea’s international co-productions. In this respect, in order to develop a comprehensive understanding of the internalization strategy of North Korea’s film productions, this paper uses the global value chain as a framework for analysis. This approach helps understand the internationalization pattern of each value chain activity of film co-productions in terms of the film location and the methods for collaborating with foreign partners. By dividing the evolution of North Korea’s international co-productions into three periods since the 1980s, this paper finds that although North Korea has shown mixed results with different aspects of the film value chain, it has generally improved its internationalization over the three periods. This paper further provides strategic directions for North Korea by learning some of the successful Chinese experiences in the film sector regarding collaboration with foreign partners—to foster a win-win situation for all involved parties.

The article is devoted to the analysis of the structure, the peculiarities of functioning and the socio-economic and political effects of the «platform capitalism». The basis of this model is the network effects produced by the integrated information and communication infrastructure, which contribute to the monopolization and the constant expansion of platform companies into new areas. The principle of functioning of this infrastructure is the continuous collection and further monetization of data extracted from the interactions of individuals among themselves or with one of the elements of a digitalized economy or government structures. Such an infrastructure — forms a potential threat of strengthening state and corporate control over citizens. In addition, the activities of platform companies produce negative effects on the labor market, reinforcing the process of precarization of employment. The integrated information and communication infrastructure of platform companies form a system of a kind of «digital Taylorism», which deprives the employee of autonomy and privacy in the workplace. The influence of digitalization, subjected to the technocratic logic of the neoliberal model of governance in democratic countries, strengthens the de-politicization of relations between the citizen and the state and further changes the balance of power between labor and capital in favor of the latter. Large-scale protests of the last years against the companies of “capitalism of platforms” demonstrated the structural contradictions of this model and formed new forms of organization and actions of grassroots workers of the “digital economy”.
