Zhumadillayeva, Ainur; Orazbayev, Batyr; Santeyeva, Saya; Dyussekeyev, Kanagat; Li, Rita Yi Man; Crabbe, M. James C.; Yue, Xiao-GuangThis study developed models to solve problems of optimisation, production, and consumption in waste management based on methods of system analysis. Mathematical models of the problems of optimisation and sustainable waste management in deterministic conditions and in a fuzzy environment were formulated. The income from production was maximised considering environmental standards that apply to the field of macro...

Corporate Social Responsibility and Maturity Mismatch of Investment and Financi...
Bao, Xiaolan; Luo, Qiaosheng; Li, Sicheng; Crabbe, M. James C.; Yue, XiaoGuangWe investigate the influence of corporate social responsibility (CSR) on the maturity mismatch of investment and financing from the perspective of both polluting and non-polluting companies. The results reveal that CSR performance can aggravate the maturity mismatch of investment and financing; and the effect can be more serious in the polluting companies. At the same time, we find that CSR makes companies obta...
Fiscal Expenditures on Science and Technology and Environmental Pollution: Evid...
Xiong, Wanfang; Han, Yan; Crabbe, M. James C.; Yue, Xiao-GuangStudying the driving factors of environmental pollution is of great importance for China. Previous literature mainly focused on the cause of national aggregate emission changes. However, research about the effect of fiscal expenditures on science and technology (FESTs) on environmental pollution is rare. Considering the large gap among cities in China, it is necessary to investigate whether and how FESTs affect...
