摘要：
This study evaluates the circular economy performance of global
chemical companies from 2013 to 2022, focusing on production efficiency
and circular efficiency. Dynamic network Data Envelopment
Analysis model is employed to assess the overall, production and circular
performance of firms. Additionally, management decision
matrix is presented, offering firms a clearer understanding of their
efficiency levels and a detailed projection analysis on the optimization
adjustments needed for both resource inputs and outputs. The
findings reveal varying levels of overall efficiency among the
observed firms. While some companies have managed to maintain
or improve their efficiency over the study period, others exhibit significant
inefficiencies. Opportunities for operational streamlining and
resource optimization are identified, particularly in reducing resource
consumption without compromising production capacity. The analysis
of circular efficiency further highlights substantial potential for
improving sustainability practices, particularly through enhanced
waste reuse and a reduction in environmental impact. This study
provides practical implication of circular economy performance in
the chemical industry, offering a new way to measure and improve
resource efficiency and sustainability practices.
