In the 21st century, with the further deepening of informationalization, competition among the steel industry chain has gradually upgraded to that of its e-commerce service. On the basis of bus-based industry chain theory, the architecture of integrated e-commerce platform in the steel industry chain is built. The platform involves upstream and downstream enterprises, including manufacturers, processing centers, trading companies, third-party logistics companies, and customers, etc. different from previous decentralized model of e-commerce platform, through the integrated e-commerce platform, customers can complete all business with one-stop, and improved their service perception and satisfaction. And new model is more promoted and implicated in other industry. The system has been applied in the enterprises, and the result is very good. The bus-based integrated e-commerce platform will become one of the paths for enterprise to further development.

As an important basic industry in Manufacturing, steel industry also is a supporting industry for city industrialization and modernization in China. With the further development of information technology, e-business in the steel industry has accounted for an increasingly large proportion in the overall development of e-business. But currently e-business system is relatively decentralized, lack of integration and service expansion capacity in the downstream industry chain. Therefore, this paper is proposed to build cloud business platform by the combination of cloud computing and e-business, introducing service module functions through the cloud and end, and forming the whole process of shared business services in the steel industry. Finally, the paper does the analysis to the effect of its application in the enterprise to prove the feasibility of the model.

Structure of the Russian export and import of steel industry products presented by results of 9 months of 2019 operation. It was shown, that the total share of pig iron, ferroalloys and semi-products (40.3%) in the ferrous metals export from Russia is practically the same as the share of rolled products and steel pipes (39.4%), whereas the shares in the import structure were 7.7 and 75% accordingly. The share the far abroad countries in the Russian export and import of finished steel products (in natural terms) accounted for 80.6 and 28.7% accordingly, while the share of CIS countries – 19.4 and 71.3% accordingly. For 9 months of 2019 the Russian export of semi-products declined by 10.9% comparing with the analogue period of 2018 and accounted for 10.9 m tons. 54.6% of the total export shipping of semi-products were directed to Mexico, Turkey, Egypt and Taiwan. Within the nearest years the Russian export of semi-products and billets, in particular, will be effected by the further development of the semi-products production in in the countries of Middle East, Turkey, Vietnam and India. The domestic market remained to be more attractive for many Russian companies. For the 9 months of 2019, export of long and flat products accounted for 3 and 5.7 m tons accordingly, declining comparing with the analogue period of the previous year by 11 and 15.6% accordingly. Import of long and flat products decreased by 12 and 0.5%, accounting for 1.0 and 2.9 m tons accordingly. By the results of 9 months of 2019, import declined and export shipping of coated sheet increased. Taking into account the expansion of steel grades assortment by Russian plants, increase of capacities for production of sheet with different coatings, this tendency is likely to remain.

Japan and the United States, the world’s largest economies for most of the past half century, have very different immigration policies. Japan is the G7 economy most closed to immigrants, while the United States is the large economy most open to immigrants. Both Japan and the United States are debating how immigrants are and can con-tribute to the competitiveness of their economies in the 21st centuries. The papers in this special issue review the employment of and impacts of immigrants in some of the key sectors of the Japanese and US economies, including agriculture, health care, science and engineering, and construction and manufacturing. For example, in Japanese agriculture migrant trainees are a fixed cost to farmers during the three years they are in Japan, while US farmers who hire mostly unauthorized migrants hire and lay off workers as needed, making labour a variable cost.
