Yunxiang Peng,Guixian Tian 한국정보처리학회 2023 Journal of information processing systems Vol.19 No.6
Conventional mining enterprises, particularly coal-related ones, exhibit substantial environmental pollution andhigh energy consumption, while those involved in new energy resources, such as lithium and cobalt, face severeresource shortages. Consequently, the economic efficiency of China’s mining enterprises is significantlyconstrained. This study examines data from nine representative listed enterprises in China spanning 2016 to2021. Employing the DEA model—i.e., BCC (VRS) model, we analyze the economic efficiency of miningenterprises with a focus on stakeholders. The paper provides static and dynamic analyses, offering insights andrecommendations for enhancing technology, reducing costs, and fortifying social relationships.
Empirical Research on the Relationship between the Futures and Spot Prices of Cotton in China
( Lin Wang ),( Guixian Tian ) 한국정보처리학회 2024 Journal of information processing systems Vol.20 No.1
This study constructed a VAR model with cotton futures and spot price data from April 30, 2009 to November 16, 2022, for empirical analysis utilizing the Granger causality test to analyze the dynamic relationship between cotton futures and spot market prices in China. The impulse response function and variance decomposition analysis showed that the cotton spot prices at flowering have a causal relationship with each other; in terms of mutual influence and impact, futures prices are higher than spot prices. Finally, it proposed countermeasures and suggestions from the perspective of establishing a standardized cotton spot market, improving the laws and regulations of the cotton futures market and trading system, and optimizing the structure of investment subjects.
