In the context of climate change,the growing cost-efficiency of Arctic shipping routes is expected to enhance maritime activities between China and Arctic countries.As one of the world's leading trade powers,China has implemented a series of policies and guidelines aimed at Arctic resource development and engagement in Arctic governance.However,the industrial interdependencies between China and Arctic countries,as well as strategies for reshaping leadership and hub roles within global interdependence frameworks,remain underexplored.This study employs global input-output tables from 2013 to 2022,utilizing input-output(IO)model and the Hubness Measurement Index(HM)to examine the industrial trade value distribution and dependency relationships between China and the Arctic countries.Our analysis identifies several key industrial sectors with higher influence coefficients,including manufacturing(1.09),wholesale and retail trade(1.07),and finance(1.04),which play significant roles in driving regional economic development in both China and Arctic countries.Furthermore,the construction sector exhibits remarkably high sensitivity coefficients(4.93)in both China and Arctic nations,followed by public administration(3.03)and professional activities(2.58),indicating strong demand-driven economic effects.Between 2013 and 2022,China's economic dependence on Arctic nations,contrasted by increased dependence on China among most Arctic countries,particularly Russia.This growing reliance stemmed principally from the robust growth of China's core industries,notably manufacturing,mining,and construction.These sectors not only fueled China's domestic economic expansion but also reshaped the trade dependency patterns of Arctic economies.This study analyzes key industrial sectors that strengthen trade between China and Arctic countries,contributing to both economic restructuring and the evolution of bilateral trade patterns.It further aims to provide policy recommendations to promote the sustainability of trade relations. 展开更多

Trade induces spatial redistribution of carbon emissions.Previous attempts to investigate the impact of trade patterns on the spatial distribution of emissions across regions in China failed to consider the special export structure of each region,leading to inaccurate results.To reassess the emissions embodiment in interregional and international exports(EEX)and quantify the underlying determinants of the EEX growth in each region,we applied the structural decomposition analysis(SDA)within a new environmental bipartite inter-regional input-output(BIRIO)framework that distinguishes processing from ordinary production.Results show that EEX growth rates are significant and vary across regions.On the demand side,the change in total ordinary exports and non-local total final demand are the major contributors to the EEX growth before and after the financial crisis,respectively.On the production side,the production technology effect reversed from positive before 2007 to negative after 2007,showing that the production process changed from emission-intensive before 2007 to decreasing emissions after that year.Overall,the processing export effect is more dominant in coastal regions,which even surpasses the ordinary export effect in South Coast from 2007 to 2012.In contrast,non-local effects dominated the EEX change in inland regions,implying their growing participation in both interregional and international production fragmentation.The results from this study shed light on who is responsible for the increased emissions and support some relevant policy recommendations. 展开更多

The influence of Impedance Boundary Condition (IBC) on transonic compressors is investigated. A systematic input–output analytical framework is developed, which treats the nonlinearities as unknown forcing terms. The framework is validated through the experiments of rotating inlet distortion within a low-speed compressor. The input–output method is subsequently applied to transonic compressors, including NASA Rotor37 and Stage35, wherein impedance optimization is studied along with the exploration of its fundamental mechanisms. The IBC is employed to model the effect of Casing Treatment (CT). The optimal complex impedance values are determined through predicted results and tested across a range of circumferential modes and forcing frequencies. The IBC significantly reduces the energy and Reynolds stress gain, notably at the first-order circumferential mode and within the Rotor Rotating Frequency (RRF) range. Output modes reveal that transonic compressors with fine-tuned impedance values exhibit a more confined perturbation distribution and redistribute the perturbations compared to the uncontrolled case. Additionally, the roles of resistance and reactance are elucidated through input–output analysis, and resistance determines the energy transfer direction between flow and pressure waves and modulates the amplitude, whereas reactance modifies the phase relationships and attenuates the perturbations. 展开更多

Purpose:The study evaluates the relative roles of Domestic-Funded Enterprises(DFEs)and Foreign-Funded Enterprises(FFEs)across Chinese provinces.It further examines how industrial structures differ by ownership at both regional and national scales.Drawing on these findings,the analysis traces the geographic shift of FFEs and offers evidence-based guidance for shaping foreign investment policy.Design/methodology/approach:This study uses Inter-Country Input-Output(ICIO)and Inter-Region Input-Output(IRIO)tables to build two extended datasets:Ownership-Extended Inter-Country Input-Output(OE-ICIO)and Ownership-Extended Multi-Region Input-Output(OE-IRIO)tables.These are then combined to construct the Regionally-Ownership Dually-Extended Multi-Regional Input-Output(RODE-MRIO)table and Global Domestic and Foreign Enterprises Network(GDFEN)model to explore the industrial relocation trends of FFEs in China.Findings:The results indicate that:(1)From 2010 to 2019,FFEs in China showed an overall decline in influence,profitability,and network robustness.(2)Eastern and developed regions saw a clear retreat of FFEs,with a shift toward domestic control.Central regions and more developed regions played a transitional role.Moreover,western and less developed regions remained stable but still relied on low-end and resource-based activities.(3)FFEs’influence has been gradually shifting towards less-developed central and western provinces due to rising labor costs and stricter environmental regulations.Research limitations:First,only general policy recommendations are proposed,without exploring the design of specific policy instruments.Second,the significant impact of recent trade measures on the behavior of FFEs has not been considered.Third,further research is needed to deepen the analysis by comparing regional ownership dynamics in China with those in other major economies.Practical implications:This research provides valuable insights for policymakers aiming to enhance regional economic development and improve China’s position within Global Value Chains(GVCs).Originality/value:The originality of this paper lies in its development of a new model that combines geographic,sectoral,and ownership dimensions.This model allows for a clearer analysis of the roles of foreign and DFEs in China’s regional economy.It offers insights into industrial transfer trends within global value chains and provides a framework for analyzing and forecasting future shifts. 展开更多

Global production networks have become the most important organizational platforms for coordinating international production activities,and their evolution patterns profoundly affect value distribution across the world.In this study,we shall firstly carry out an in-depth quantitative research to analyze the patterns and evolution of global production networks,using a long time-sequenced multi-region input-output table and the network analysis approach.Then based on the method of value-added decomposition,we will develop an index system to measure the degree of participation of regions in global production networks.Finally,we will try to identify the factors affecting the degree of participation of countries in global production networks by constructing a regression model.The results show that from 1995 to 2015,the evolution of global production networks measured by input-output linkages experienced four stages:expansion,contraction,re-expansion,and re-contraction.In addition,the core communities of global production networks evolved from two major production communities(Europe and the Americas)to three pillars(Europe,Americas,and Asia)while more segmented communities are mainly affected by geographical proximity.The latter consists of European,North American,South American,African and Asian communities.The evolution of the global production network pattern primarily manifests as a process of cooperation strengthening or weakening among communities,based on changes in the external environment and the need for individual development strategies.Meanwhile,the United States,Germany,and the United Kingdom have consistently ranked among the top entities in global production networks,whereas China,Russia,and Southeast Asia have the fastest rises in ranking.In addition,government efficiency,resources endowment,infrastructure conditions and technology levels play important roles in the participation in global production networks. 展开更多

Based on input-output approach, the robust stability and stabilization problems for uncertain singular systems with time-varying delays are investigated. The parameter uncertainties are assumed to be norm-bounded and the time-varying delays include both discrete delay and distributed delay. By introducing a new input-output model, the time-delay system is embedded in a family of systems with a forward system without time delay and a dynamical feedback uncertainty. A sufficient and necessary condition, which guarantees the system regular, impulse-free and stable for all admissible uncertainties, is obtained. Based on the strict linear matrix inequality, the desired robust state feedback controller is also obtained. Finally, a numerical example is provided to demonstrate the application of the proposed method. 展开更多

Industrial wastewater discharge in China is increasing with the country′s economic development and it is worthy of concern. The discharge is primarily relevant to the direct discharge coefficient of each sector of the economy, its direct input coefficient and the final demand in input-output models. In this study, we calculated the sensitivity of the reduction in the Chinese industrial wastewater discharge using the direct input coefficients based on the theory of error-transmission in an input-output framework. Using input-output models, we calculated the direct and total industrial wastewater discharge coefficients. Analysis of 2007 input-output data of 30 sectors of the Chinese economy and of 30 provincial regions of China indicates that by lowering their direct input coefficients, the manufacturers of textiles, paper and paper products, chemical products, smelting and metal pressing, telecommunication equipment, computers and other electronic equipment will significantly reduce their amounts of industrial wastewater discharge. By lowering intra-provincial direct input coefficients to industrial sectors themselves of Jiangsu, Shandong and Zhejiang, there will be a significant reduction in industrial wastewater discharge for the country as a whole. Investment in production technology and improvement in organizational efficiency in these sectors and in these provinces can help lessen the direct input coefficients, thereby effectively achieving a reduction in industrial wastewater discharge in China via industrial restructuring. 展开更多

We propose a scheme to purify entanglement of two atoms from not-too-impure entangled states by checking the parity of the two atoms through the cavity input-output process. As the parity check is made by measurement on single-photon polarization, which would not affect the entanglement of the two atoms, our scheme has the successful probability double of that in a previous well-known scheme with linear optical elements [Nature （London） 410 （2001） 1067], and is insensitive to the photon loss and the detection inefficieney. Experimental feasibility of our scheme with current technology is discussed. 展开更多

This paper addresses the robust input-output energy decoupling problem for uncertain singular systems in which all parameter matrices except E exist as time-varying uncertainties. By means of linear matrix inequalities (LMIs), sufficient conditions are derived for the existence of linear state feedback and input transformation control laws, such that the resulting closed-loop uncertain singular system is generalized quadratically stable and the energy of every input controls mainly the energy of a corresponding output, and influences the energy of other outputs as weakly as possible.

To promote sustainability, it has become increasingly vital to properly account material and energy flows in industrial production processes. Therefore, a generic process-level input-output （IO） model was developed to provide an integrated energy （material） accounting and analysis approach for industrial production processes. By extending the existing processlevel IO models, the production, usage, export and loss of by-products were explicitly considered in the proposed IO model. Moreover, the by-products allocation procedures were incorporated into the proposed IO model to reflect individual contributions of products to energy consumption. Finally, the proposed model enabled calculating embodied energy of main products and total energy consumption under hierarchical accounting scope. Plant managers, energy management consultants, governmental officials and academic researchers could use this input-output model to account material and energy flows, thus calculating energy consumption indicators of a production process with their specific system boundary requirements. The accounting results could be further used for energy labeling, identifying bottlenecks of production activities, evaluating industrial symbiosis effects, improving materials and energy utilization efficiency, etc. The model could also be used as a planning tool to determine the effect that a particular change of technology and supply chains may have on the industrial production processes. The proposed model was tested and applied in a real integrated steel mill, which also provided the reference results for related researches. At last, some concepts, computational issues and limi- tations of the proposed model were discussed. 展开更多

The development of any analytical method should have to experience at least four stages: its initial status, growth, mature and declining. However, although the regional input-output analysis has been widely applied for more than forty years, it is still one of the most important approach in regional economic analysis and forecast at present in the world. This is due to the never ended modifications and its great potentials. In this paper, we review the historical development of the regional input-output analysis. 展开更多

Based on a refined ＂non-competitive input-output model,＂ this paper proposes a new framework for analyzing the status of a country＇s high-tech industries in the international division of labor, i.e. calculates the index of＂ weighted value-added productivity ＂ by compiling non-competitive input-output tables which distinguish high-tech industries from traditional industries. The new method effectively avoids ＂statistical illusion＂ which stems from a biased focus on gross exports under intra-product specialization. The empirical study shows that since 1995, the status of China＇s high-tech industries has grown quickly as a result of enhanced labor productivity, but still lags behind those of major developed countries. In addition, the study also suggests that the status of China＇s high-tech industries has been over-estimated using the traditional gross export statistical method. 展开更多

Becoming the world's largest emitter of carbon makes China the object of criticism;however,people may ignore the fact that when China exports low-carbon products,the carbon emissions have been left in the meanwhile,forming the so-called"embodied carbon".Using the input-output model,this paper analyzes the carbon emission intensity and amount of embodied carbon of various sectors in China's export trade in 2002 and 2007,and filters out high carbon emission sectors.In addition,this paper also points out the problem of carbon emissions'international transfer from developed countries to China through the analysis of national and regional flow of export carbon emissions and changing of the proportion of emissions for exports relative to total emissions,and explains the reason that caused carbon transfer to China by using the treadmill of production theory.Based on that,this paper proposes some measures for carbon reduction in China from the foreign trade perspective. 展开更多

In this paper, we attempted to calculate the impact of environmental regulation on the international competitiveness of China＇s industries. Calculations are based on the input-output model that incorporates pollution control costs. We took enterprises ＇pollution control costs as the substitute variable for environmental regulation and price changes to measure the impact on international competitiveness for all sectors. Our studies reported three findings. First, price rises caused by pollution control costs were not more than 4 per cent in the manufacturing and trade sectors in 2007. Second, although the charging rate on pollutant discharge has become increasingly higher since 2003, the resultant price rise is only around O. 5 per cent across all sectors. Third, the impact brought about by increasingly stronger environmental regulation is limited and the resultant price rise does not exceed 2 per cent. Thesefindings indicate that the impact of environmental regulation on China＇s trade sectors is affordable. Therefore, it is needless to worry that environmental regulation will weaken the international competitiveness of Chinese products. 展开更多

An input-output signal selection based on Phillips-Heffron model of a parallel high voltage alternative current/high voltage direct current(HVAC/HVDC) power system is presented to study power system stability. It is well known that appropriate coupling of inputs-outputs signals in the multivariable HVDC-HVAC system can improve the performance of designed supplemetary controller. In this work, different analysis techniques are used to measure controllability and observability of electromechanical oscillation mode. Also inputs–outputs interactions are considered and suggestions are drawn to select the best signal pair through the system inputs-outputs. In addition, a supplementary online adaptive controller for nonlinear HVDC to damp low frequency oscillations in a weakly connected system is proposed. The results obtained using MATLAB software show that the best output-input for damping controller design is rotor speed deviation as out put and phase angle of rectifier as in put. Also response of system equipped with adaptive damping controller based on HVDC system has appropriate performance when it is faced with faults and disturbance. 展开更多

Under the pressure of sustained growth in energy consumption in China,the implementation of a carbon pricing mechanism is an effective economic policy measure for promoting emission reduction,as well as a hotspot of research among scholars and policy makers.In this paper,the effects of carbon prices on Beijing's economy are analyzed using input-output tables.The carbon price costs are levied in accordance with the products'embodied carbon emission.By calculation,given the carbon price rate of 10 RMB-CO_2,the total carbon costs of Beijing account for approximately 0.22-0.40%of its gross revenue the same year.Among all industries,construction bears the largest carbon cost Among export sectors,the coal mining and washing industry has much higher export carbon price intensity than other industries.Apart from traditional energy-intensive industries,tertiary industry,which accounts for more than 70%of Beijing's economy,also bears a major carbon cost because of its large economic size.However,from 2007 to 2010,adjustment of the investment structure has reduced the emission intensity in investment sectors,contributing to the reduction of overall emissions and carbon price intensity. 展开更多
