Determinants of natural disaster emergency public investment cycles in central and southern Chinese regions: The role of technological innovation efficiency

This paper analyses the disaster emergency public investment performance against the background of carbon emissions using the super-efficiency DEA and Malmquist models combined with emergency management and handling methods. A comprehensive and systematic analysis of the performance of natural disaster emergency public investment in the central and southern regions found deficiencies in current emergency performance due to inadequate legislation, inadequate resource allocation, and lack of prevention knowledge among the public. Further research results indicate that various provinces in the central and southern regions attach great importance to emergency public investment in natural disasters, mainly through the influence of scale efficiency and technical efficiency, which promotes enhancement in productivity, thus, the increase of emergency public investment rate. Technical efficiency positively impacts output, and some provinces have differences in their natural disaster emergency public investment rates due to the slow growth of technological progress. Therefore, specific measures will be gradually implemented to address the influencing factors.
