China ‘s new energy vehicle industry is expanding as a strategic emerging industry and has become an important force in industrial upgrading. Its supply chain has been prolonged, detailed, and its industrial structure has been developing. Uncertain external environment and increasingly complicated internal structure make it important to understand the evolutionary mechanism and developing law of new energy vehicle industry. This paper, aiming at exploring the endogenous development mechanism of China ‘s new energy vehicle industry, uses China ‘s new energy vehicle trading data from 2008 to 2020 to establish a supply-demand dependance network among listed companies of this industry, and studies its evolutionary characteristics. Empirical research is carried out to verify evolutionary mechanism of the supply-demand dependance network based on financial data and public sentiment data, via stochastic actor-oriented model from three dimensions of endogenous network structure, situation factors and company attributes. China ‘s new energy vehicle industry shows a local-centralized supply-demand dependence structure, and regional leading enterprises are boosting their abilities in controlling supply chain. Formation and evolution of industrial supply-demand dependence network is impacted by endogenous mechanism, such as preference attachment effect and triangle loop effect, and promoted by co-executive relationship. This paper presents suggestions for advancing China ‘s new energy vehicle industry on regional commercial cooperation, optimizing co-executive relationship and caring vulnerable companies.Governments and professional associations should continue boosting industrial cluster construction and supporting regional integration on policies and standards, enhancing free migration of capital, technical and industrial data.Industrial policies are adjusted to optimize industrial demand-supply relation through constraining or promoting co-executive relationship.Tracking commercial sentiment can recognize potential dependance relation, comprehend industrial network dependance structure, helpful in directing investment and recognizing risks. Governments shall take care of vulnerable companies, be vigilant on industrial structural imbalance, and also pay attention to notable companies with higher standard operating code and supervision, fully disclosing their financial information.

The world enters a new period of the fourth industrial revolution and the sixth technical revolution. The emerging new industries stimulate the demands of such mineral resources as lithium, cobalt, nickel and rare earth elements. To secure safe and sustainable development of strategic new industries, the major nations and economic units boost a guarantee of their strategic and key minerals, and issue a catalogue of strategic and key minerals appropriate for their situation. Mineral resources security refers to not only up-stream supply security, but also processing and transportation security. This paper, based on the latest policies and catalogues of China, USA, Europe and Japan, gives a summary from three aspects, namely the whole industrial chain definition of strategic mineral resources, research advances and research challenges. It also presents four frontier subjects for researching industrial chain of strategic mineral resources: whole industrial chain system margin and new content of resources security viewing from whole industrial chain, the complicated system construction of "trade-production-circulation" whole industrial chain, approaches to sustainable development of whole industrial chain of mineral resources with carbon peak and carbon neutrality objectives, and interactive mechanism among innovative chain, value chain, industrial chain, supply chain and capital chain.

The global competitiveness of modern companies lie not only in technology and capital, but also in global operating capacity of industrial chain, supply chain and value chain, which requires further studies on industrial chain. This paper, based on references regarding copper industrial chain globally, discusses four aspects of cooper chain in defining the concept of industrial chain, research target, research points and research methods. The concept has yet to be defined at an agreed manner. Research targets seldom cover the entire copper industrial chain. Research points does not treat industrial chain as a complicated system. Static and sole research methods prevail. This paper presents the future research direction of industrial chain on intact, dynamic, accurate models and methods.

This paper,based on acase study on Ontario,analyzes its management system of non-radio active tailings in administration,responsibilities,laws,regulations,permits and industrial guidelines,and summarizes Canada’s management features,aiming at providing reference for China to manage tailings.Canada’s sound tailings management is embodied by appropriate decentralization,laws and regulations,industrial guidelines,marketing and enterprises’ cooperation.China shall optimize tailings management system from clarifying rights and responsibilities,improving managing level and boosting enterprises’ awareness of tailings management.
