Decent Work and Industrial Upgrading in Global Production Network: a Case of China Apparel Industry

China apparel industry, which is deeply embedded in the global production network (GPN), faces two urgent issues, social upgrading and economic upgrading. The study of GPN places great emphasis on the two issues. Based on the survey of Ningbo apparel industry, four key components of decent work in China apparel industry are discussed. The role of buyers in promoting decent work in suppliers can't be neglected. There are significant correlations between business type and some indicators of decent work. Though the majority of the apparel firms are engaging in processing, more and more firms are involved in marketing and branding. The upgrading trajectory of China apparel industry leads to the economic and social performances.

Territory-based and Ownershipbased Gains from Trade under the Global Production Network——An Empirical Study Based on China

Under global production network,export cannot represent a country's gains from trade,and territory-based gains from trade refer to the remainder of export after deducting the input of intermediate goods and re-export after value-added return.Ownership-based gains from trade refer to the remainder of territory-based gains from trade after further deducting the trade in value added(TVA) realized through the inflow of foreign factors.By creating a multicountry input and output model,this paper calculates the territory-based gains from trade,ownership-based gains from trade,and territory-based gains from trade for foreign countries realized through China's export,as well as valueadded return and territory-based gains from trade for foreign countries realized through China's import.This paper has arrived at the following conclusions:behind China's status as the largest goods exporting country in the world,most of Chinese exports contribute to the gains of foreign countries;value addition for foreign countries realized through China's export and value-added return realized through China's import mostly come from Taiwan region,Japan and South Korea in East Asia;a considerable part of gains from trade for the United States realized through China-US trade is achieved through indirect trade.

‘Partly'globalized networks and driving mechanism in resource-based state-owned enterprises:A case study of J Group

In the context of economic globalization,while multinational enterprises from developed countries occupy a high-end position in the global value chain,enterprises from developing countries are often marginalized in the world market.In China,resource-based state-owned enterprises(SOEs)are tasked with the mission of safeguarding resource security,and their internationalization development ideas and strategic deployment are significantly and fundamentally different from those of other non-state-owned enterprises and large multinational corporations.This study provides ideas for the globalization policies of enterprises in developing countries.We consider J Group in western China as a case and discuss its productive investment and global production network development from 2010 to 2019.We found that J Group was‘Partly'globalized,and there are multiple core nodes with the characteristics of centralized and decentralized coexistence in the production network;in addition,the overall layout centre shifted to Southeast Asia and China;however,its global production was restricted by the enterprise's investment security considerations,support and restrictions of the home country,political security risk of the host country,and sanctions from the West.These findings provide insights for future research:under the wave of anti-globalization and'internal circulation as the main body',resource SOEs should consider the potential risk of investment,especially keeping the middle and downstream industrial chain in China as much as possible.

Shock Propagation in Dual-Circulation Production Networks:Characteristics and Simulation

This article constructs a dual-circulation production network framework on the basis of integrating inter-country and China's multi-regional input-output tables,identifies the propagation and attenuation of sectoral shocks in dual-circulation production networks,and measures the effects of US-China trade frictions on the networks.The research finds that:(1)The asymmetry between domestic-and internationalcirculation production networks has increased,and with a few sectors becoming key sectors to dual-circulation production networks,sectoral shocks grow increasingly critical for aggregate volatility.(2)Based on the above analytical framework,the global extraction method(GEM)is adopted to simulate the GDP losses in scenarios of China-US industry-wide chain interruptions,certain sectoral frictions,and supplyside and demand-side chain interruptions.The simulation finds that increasing the domestic substitution rate will reduce the value losses caused by China-US chain interruptions,which is applied for both countries.However,even if full substitution can be achieved,the value losses cannot be avoided completely in the China-US decoupling.Whether it is the demand-side chain interruptions plus insufficient market substitution in China,or the supply-side chain interruptions plus insufficient supply substitution in the US,will cause great losses to their economy.

Global Production Network and the Upgrading of China's Integrated Circuit Industry

Using an analytical framework of the global production network （GPN）, the present paper examines the external environment and the internal dynamics of China＇s integrated circuit （IC） industry. We analyze the transition of China＇s IC industry from a state-led integrated device manufacturers＇ model to deeper integration into the GPN. We also explore the technological sources, the upgrading dynamics as well as the positioning of different nodes of China＇s IC industry in the GPN. We conclude that the ＂East Asia model＇＂ of gradual industrial upgrading might not apply anymore in the new era of GPN. High-technology industries can now be upgraded based on a parallel evolution model. Policy implications for China＇s high-technology industrial upgrading strategies are drawn from our analysis.

Impact of the US Economic Crisis on East Asian Economies:Production Networks and Triangular Trade through Chinese Mainland

This paper investigates the impact of the 2008 economic crisis on industries in East Asia. It attempts to identify the transmission mechanism and the magnitude of the impact of the crisis on industries in East Asia using the updated Asian international input-output table for 2008. The analyses reveal that the crisis significantly affected industrial output of the nine East Asian economies included in the present study. The economies that are deeply involved in production networks were affected most seriously. Our analyses also show that the impact was transmitted to East Asian industries through triangular trade, in which Chinese mainland imports parts and components from neighboring East Asian economies and then exports final products to the US and EU markets. Although such intricate production networks have improved the competitiveness of East Asian economies, they have also increased vulnerability to external shocks.

BOTTLENECKS IN PRODUCTION NETWORKS: AN OVERVIEW

Bottlenecks, the key ingredients for improving the performances of the production networks, have been profoundly studied during the last decade. Yet, because of the complexity of the research results, there is still a significant gap between theory and practice. In this paper, we review various bottleneck definitions, detection methods and the asymptotic results and provide a practical guidance for recognizing and utilizing the bottlenecks in production networks. Queueing theory works as the mathematical foundation in our study. Various definitions of the bottlenecks are classified as either Performance in Processing （PIP） based or sensitivity based definitions, which reflect the preferences of the managers. Detection methods are surveyed closely based on the definitions. These methods are used to recognize the bottlenecks and to provide diagnosis results to managers. Comparisons show that different detection methods may lead to vastly different conclusions. The recognition of the bottlenecks has another advantage： the ultimate phenomena of the bottlenecks can greatly reduce the computation complexity in calculating the system performances. Bottlenecks based approximation and asymptotic results are studied to exhibit the contribution of bottlenecks in performance estimation and theoretical analysis.

Production network flexibility:case study of Norwegian diary production network

By increasing advances in the production net- works planning, understanding of relations and dynamics of production networks is gaining more attention in order to use all network capabilities. To achieve this under- standing, it is not only important to have a good under- standing of individual firm＇s manufacturing flexibility next to supply chain flexibility, but also to consider the internal （among production network＇s facilities） and external （other tiers of supply chain） relationships in a production network. Studying the production network＇s flexibility dimensions facilitates the effective use of the synergy of cooperation in the network. On other words, the potential in the network structure cannot be exploited unless the planning and control of network consider the available flexibility of network and operationalize the opportunities which arise. This paper identifies different dimensions of flexibility in a production network and describes how they can support firms in responding to customers＇ needs. This research employs exploratory and descriptive approaches and uses a single case study of Norwegian diary to capture the dynamics of production networks. Three product categories with different network characteristics are selected, and the identified network flexibility dimensions are investigated for these products. The status of case company under each flexibility dimension is presented and discussed.

A Study of Optimum Switching Problem for Production Systems Considering Efficiency, Delivery Time and Green Evaluation

This paper aims to derive the optimal switching strategy for production system considering efficiency, delivery time and green evaluation. Nowadays more and more manufacturing and logistics systems not only pursue better work efficiency, but also focus on green energy evaluation issues. Cost reduction and shortening of delivery time are always important management issues in pursuit of efficiency and optimization of the entire production system because of global production competition. In a market situation where customer needs change in various ways, in particular, due to inadequate quality, changes in the local environment, natural disasters and so on. Therefore, prompt planning of management measures such as switching work processes and changing production methods has become an important issue. On the other hand, since the Paris Agreement came into effect, the construction of an environment-friendly production system has been required as an approach to environmental problems such as global warming. In this paper, we propose an optimum switching model of production systems considering efficiency, delivery time and green evaluation using a green evaluation index (GEC: Green Energy Coefficient). We also discuss the optimal switching strategy by numerical observation.

Coal mine safety production forewarning based on improved BP neural network

Firstly, the early warning index system of coal mine safety production was given from four aspects as per- sonnel, environment, equipment and management. Then, improvement measures which are additional momentum method, adaptive learning rate, particle swarm optimization algorithm, variable weight method and asynchronous learning factor, are used to optimize BP neural network models. Further, the models are applied to a comparative study on coal mine safety warning instance. Results show that the identification precision of MPSO-BP network model is higher than GBP and PSO-BP model, and MPSO- BP model can not only effectively reduce the possibility of the network falling into a local minimum point, but also has fast convergence and high precision, which will provide the scientific basis for the forewarnin~ management of coal mine safetv production.

Modelling the impact of climate change on rangeland forage production using a generalized regression neural network:a case study in Isfahan Province,Central Iran

Monitoring of rangeland forage production at specified spatial and temporal scales is necessary for grazing management and also for implementation of rehabilitation projects in rangelands. This study focused on the capability of a generalized regression neural network（GRNN） model combined with GIS techniques to explore the impact of climate change on rangeland forage production. Specifically, a dataset of 115 monitored records of forage production were collected from 16 rangeland sites during the period 1998–2007 in Isfahan Province, Central Iran. Neural network models were designed using the monitored forage production values and available environmental data（including climate and topography data）, and the performance of each network model was assessed using the mean estimation error（MEE）, model efficiency factor（MEF）, and correlation coefficient（r）. The best neural network model was then selected and further applied to predict the forage production of rangelands in the future（in 2030 and 2080） under A1 B climate change scenario using Hadley Centre coupled model. The present and future forage production maps were also produced. Rangeland forage production exhibited strong correlations with environmental factors, such as slope, elevation, aspect and annual temperature. The present forage production in the study area varied from 25.6 to 574.1 kg/hm^2. Under climate change scenario, the annual temperature was predicted to increase and the annual precipitation was predicted to decrease. The prediction maps of forage production in the future indicated that the area with low level of forage production（0–100 kg/hm^2） will increase while the areas with moderate, moderately high and high levels of forage production（≥100 kg/hm^2） will decrease both in 2030 and in 2080, which may be attributable to the increasing annual temperature and decreasing annual precipitation. It was predicted that forage production of rangelands will decrease in the next couple of decades, especially in the western and southern parts of Isfahan Province. These changes are more pronounced in elevations between 2200 and 2900 m. Therefore, rangeland managers have to cope with these changes by holistic management approaches through mitigation and human adaptations.

Robust digital receiver for EPC sensor network

A robust digital receiver based on a matched filter （MF） is proposed for the radio frequency identification （RFID） reader system to enhance the reliability of signal processing in the electronic product code （EPC） sensor network （ESN）. The performance of the proposed receiver is investigated by examining the anti-collision algorithm in the EPC global Class1 Generation2 protocol. The validity and usefulness are demonstrated by both computer simulations and experiments. Based on the verification results, comparing with the conventional zero crossing detector （ZCD） based receiver, the proposed receiver is very robust against strong amplitude distortions and considerable frequency deviations happening on the backscattered signal from a passive tag.

Image Rain Removal Using Conditional Generative Networks Incorporating

The research of removing rain from pictures or videos has always been an important topic in the field of computer vision and image processing. Most noise reduction methods more or less remove texture details in rain-free areas, resulting in an over-smoothing effect in the restored background. The research on image noise removal is very meaningful. We exploit the powerful generative power of a modified generative adversarial network (CGAN) by enforcing an additional condition that makes the derained image indistinguishable from its corresponding ground-truth clean image. An efficient and lightweight attention machine mechanism NAM is introduced in the generator, and an IDN-CGAN model is proposed to capture image salient features through attention operations. Taking advantage of the mutual information in different dimensions of the features to further suppress insignificant channels or pixels to ensure better visual quality, we also introduce a new fine-grained loss function in the generator-discriminator pair, predicting and real data degree of disparity to achieve improved results.

China’s Changing Economic Structure and Implications for Regional Patterns of Trade,Production and Integration

Without intending to do so, China has in recent years played a major role in East Asia＇s economic integration. It has done so mainly through the production and supply chain networks it has spun across the region. This paper argues that given the developmental trends in the Chinese economy, the Chinese government should pursue a more active strategy towards a broader and more balanced economic integration with the region. The emergence of a multi-track production structure, increased importance of domestic consumption and the services sector, together with faster integration of the domestic economy, will fundamentally change China＇s trade and investment relationships with the rest of East Asia and necessitate a review of China＇s economic integration strategy. The paper also argues that ASEAN can play a useful role in facilitating the region-wide integration process.

Which sectors should be covered by the EU Carbon Border Adjustment Mechanism?

The European Union(EU)is developing the Carbon Border Adjustment Mechanism(CBAM)to address carbon leakage in international trade.However,the EU has paid inadequate attention to input-output linkages,specifically those in the steel,aluminum,and fertiliser industries.This study aims to identify priority sectors eligible for initial regulation within the emissions-intensive trade-exposed(EITE)industries based on input-output linkages and compare its impacts with the current CBAM sector coverage.This study constructs a Global Production Network(GPN)and Carbon Flow Network(CFN)to present the input trade and embodied carbon flows for the EITE industries.This study highlights the role of the EITE industries as influential nodes in the production network and how the EITE industries in the EU contribute to carbon emissions.To improve the economy and political acceptability,CABM should cover four priority sectors with low economic impacts but a crucial role in reducing emissions,such as plastics,phosphorus fertiliser,aluminum,and copper industry.
