The article reveals the operating rules of the interaction between the industrial undertaking capacity and the global value chain position of East Asian countries by calculating the Global Moran Index(Moran’s I), coupling coordination degree and other indicators. The results show that: in time, the values of industrial undertaking capacity and the positions of global value chain in East Asian countries showed a sustained and stable growth trend, and have a consistent trend of change. Spatially, both of the two indexes had significant positive spatial correlation, with Moran’s I showing an ‘inverted U’pattern, and the spatial aggregation distribution of global value chain position lagged behind the spatial aggregation distribution of industrial undertaking capacity by one year. In terms of spatial coupling coordination, the coupling coordination values of the two indicators show a steady upward trend. Combined with the comparative advantage of each country, this paper provides suggestions for promoting the positions of Chinese and other East Asian industries in the global value chain from the perspectives of enhancing independent innovation capability and upgrading industrial structure.展开更多

The results show that the improvement of global value chain position could significantly reduce the carbon emissions of China's manufacturing industry. In addition,foreign investment and energy structure hindered the low-carbon development of China's manufacturing industry. The effects of population size and research intensity on the carbon emissions of manufacturing industry were not significant. In the process of participating in the global value chain,China's manufacturing industry should effectively reduce carbon emissions by strengthening environmental regulation,optimizing energy structure and improving production technology.展开更多

Willa Cather provides us two sets of values.To some people, success is measured in terms of money. To some success means choosing one’s own life and realizing one’s own values. In the novel The Sculptor’s Funeral Cather portrays an artist, who breaks the bondage of the old environment, and becomes a successful sculptor. However, he is regarded as a failure by his local people because the values by which they judge success are not the same.展开更多

Total value refers to the "net value" by subtracting "negative value" from "positive value". The "positive value" is the direct value of products provided by the economic entities, and the "negative value" refers to the value loss caused by the negative influence of economic entities on resource environment and social economy. This paper makes exposition of circular economy from three aspects: circulation of material units in the production process within economic entities is the core of circular economy; circular economy aims at bringing material units out the economic entities by being affiliated to products; branding material units with value for recycling in economic entities is the guarantee of circular economy.展开更多

In addition, valueadded trade is taken into consideration to identify the labor division characteristics of the four economies in the GVC, which led to the following findings: China participates primarily in the single links of the GVC at the downstream yet shows a significant tendency to move upstream in technology-intensive sectors; Japan participates primarily in the single links of the GVC at the upstream and boasts an advantage in technology-intensive sectors; the US participates in the multiple links of the GVC at the upstream with superiority in hightechnology sectors; the EU participates in the production and export of intermediate goods and final goods at both ends.展开更多
