Production and life action are changed because of the scarcity of natural resources. It is a reasonable choice that low-carbon economy, cut costs, energy-saving emission reduction under the conditions of today's limited resources. Pareto Optimal could be achieved with scientific management being as complementary production factor that can optimize and allocate the resources, adjust the ratio of production relations between the various factors under certain technical conditions. The socio-economic development and ecological environment construction have been seriously affected by factors of production shortage of water resources.Innovation of scientific management is the key toraising the level of water resources management in order to achieve maximum output at the lowest investment. The meaning and necessity of innovation and scientific management of water resources are put forward. The scientific management, technical support, system innovation, institutional innovation are discussed, and theoretical innovation of water resources management of innovation is outlined in this paper.
Purpose - This paper empirically explores the RCA of electrical equipment trade between China and Korea from the perspective of gross trade and value-added trade. The goal of this paper is to scan the electrical equipment's RCA, the decomposition of gross exports, and the impacts of an exerted shock.
Design/methodology - We applied the domestic value-added method in measuring the RCA, which could be more accurate than traditional RCA since it excludes foreign value-added. Based on the research purpose, this paper follows the framework of Koopman, Wang, and Wei (2014)—as extended by Wang, Wei, and Zhu (2018). It extracts the data from the 2019 Multi-regional Input-Output (MRIO) databases compiled by the Asian Development Bank in January 2021.
Findings - After rigorous examination, the main findings are as follows: First, the electrical equipment sector maintains a consistent comparative advantage in either assessing method. Second, China exports more gross goods of electrical equipment to the world than South Korea does, but there is a trade deficit with Korea. Third, South Korea and P.R. China are the most significant bilateral partners of foreign value-added sourcing. Finally, it is surprising that there is a shock on electrical equipment; the partner’s service, as well as manufacturing sectors, would be affected.
Originality/value - This paper explores the revealed comparative advantage between Korea and China from traditional gross export and value-added perspectives. Second, we apply the information from the 2019 MRIO database compiled by the Asian Development Bank in January 2021, reflecting the current situation. Third, this paper analyzes the electrical equipment and the impacts on other parties’ sectors. Finally, we carry out the subjects that deserve to be investigated in the future.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
