[Journal Article]ZHAO Luyang, SONG Hongzhu, ZHU Defu et al.-Coal Economic Research2024, No.z1

Abstract:China is a significant consumer of aluminum,but it faces challenges due to the relatively small amount of bauxite resources with medium quality.Additionally,a substantial portion of bauxite resources in China coexist with coal deposits.The efficient and coordinated exploration,development,and utilization of these co-existing coal and aluminum resources have been long-standing challenges in the bauxite industry.This paper introduces the types,distribution,and occurrence of bauxite in China,along with the main co-development modes of coal and aluminum resources.It also discusses new methods and technologies such as in-situ leaching mining.Building on this foundation,we propose a development concept known as"joint layout-in-situ modification-strip filling"based on the"theory and method of co-mining of coal and aluminum"to address the primary challenges of simultaneous mining and storage of coal and aluminum in our country.The paper also delves into key methods and technologies for the coordinated exploration and development of coal and aluminum symbiotic resources.This includes considerations for the occurrence relationship,co-mining system construction,green mining technology for in-situ modification of aluminum beneath coal deposits,coordinated mining methods for coal and aluminum,and the control mechanisms of rock formation.The goal of this exploration is to provide an effective path for the safe,environmentally friendly,and efficient development of coal and aluminum symbiotic resources."

Impact of green finance on new productivity:Effects,mechanisms and regional heterogeneity
[Journal Article]JIANG Xuehai, SU Ruoci, TANG Huanmin et al.-Coal Economic Research2025, No.11

Abstract:Studying the impact of green finance on new productivity is of great significance for understanding the role mechanism of green finance in innovation-driven development,promoting high-quality economic development,and realizing Chinese-style modernization.Based on the panel data of 30 provincial administrative regions in China(excluding Tibet,Hong Kong,Macao and Taiwan)from 2012 to 2022,this paper empirically tests the effects,mechanisms and regional heterogeneity of green finance on new productivity by constructing a two-way fixed effect model and an intermediary effect model.The research shows that:① Green finance has a significant effect on promoting new quality productivity,and this conclusion is still valid after robustness tests such as instrumental variable method,dynamic panel analysis and explanatory variable substitution;②Mechanism analysis shows that green finance indirectly promotes the development of new productivity through green technology innovation channels,and green technology innovation plays a partial intermediary role in this process;③ Heterogeneity analysis found that there are significant regional differences in the promotion effect of green finance on new productivity,and the promotion effect in the eastern region is significantly stronger than that in the central and western regions.Finally,suggestions are made from the aspects of strengthening the direct effect of green finance and the intermediary effect of green technology innovation,and implementing differentiated policies.

[Journal Article]LIU Yang, LIU Dawei, LIANG Feng et al.-Coal Economic Research2025, No.11

Abstract:With the advancement of the dual carbon goals,integrating high proportions of renewable energy into industrial park energy systems has become a prevailing trend.However,the randomness and volatility of renewable energy output pose significant challenges to the economic efficiency and operational reliability of such systems.This paper proposes an integrated configuration method for power generation,grid,load,and storage systems in industrial parks designed for high renewable energy penetration.By incorporating the"virtual energy storage"characteristics of thermal systems and multi-energy complementary mechanisms,a capacity planning model for industrial parks is established.This approach leverages the thermal inertia and transmission delay characteristics of heating networks to smooth electricity fluctuations,thereby reducing reliance on electrochemical energy storage.A multi-strategy enhanced Pied Kingfisher Optimizer is designed to enhance the solution capability for high-dimensional complex problems.Case simulation results demonstrate that the proposed method significantly reduces total system costs while improving source-load matching efficiency,validating its effectiveness in enhancing local consumption capacity and operational economics for renewable energy.
