基于CH-DEA模型的中国制造业产业安全研究OACSTPCD

At the beginning of 2020,the global outbreak of the COVID-19 had a substantial impact on China's manufacturing sector,which in turn had an impact on the steady growth of the entire economy.Therefore,it is imperative to analyze the security situation of the manufacturing industry to deal with manufacturing security risks.This paper innovatively proposes cross hierarchical data envelopment analysis(CH-DEA)and establishes the index framework for manufacturing security evaluation.The results indicate that from 2005 to 2020,the overall security situation of the manufacturing industry has improved,i.e.,the ability of manufacturing industry to cope with emergencies and independent development is constantly improving.The examination of micro-obstacle factors reveals that the current barrier is the shrinkage of the industry scale,which ought to be strengthened by utilizing the capacity for scientific research and innovation.The examination of macro-environmental factors indicates that the GDP and product market are positively correlated with the manufacturing industry security.Benign market competition may encourage manufacturing enterprises to invest more to adopt large-scale production and upgrade equipment,thereby enhancing competitiveness.
