Finally, CDDP-RT-qPCR was compared with RT-qPCR alone for the detection of SARS-CoV-2 in 16 raw wastewater samples collected in the Greater Tokyo Area. Five samples were positive for SARS-CoV-2 when evaluated by RT-qPCR alone. However, intact SARS-CoV-2 was detected in only three positive samples when determined by CDDP-RT-qPCR. Although CDDP-RT-qPCR was unable to determine the infectivity of SARS-CoV-2 in wastewater, this method could improve the interpretation of positive results of SARS-CoV-2 obtained by RT-qPCR.Climate change caused by rapid increases in greenhouse gas concentrations is now a global challenge. Foreign direct investment (FDI), as a key player in global economic growth, is a major contributor to carbon emissions. Based on panel data of 30 provinces in China collected from 2007 to 2018, this paper uses the two-tier stochastic frontier model to analyse the opposing two-sided effects of FDI on carbon emission performance and calculates their combined effects. The empirical study shows that FDI has both a promoting and an inhibiting effect on carbon emission performance, and the overall effect is characterized by less of an inhibiting effect than a promoting effect, resulting in the positive driving characteristic of the combined effect. The average inhibiting effect is 0.0402, and the average promoting effect is 0.1065, causing the comprehensive effect of FDI on carbon emission performance to have an average value of 0.0663. The empirical results also show that the promoting effects of FDI are greater than the inhibiting effects in most regions; however, after 2013, the level of the promoting effect declined overall. There are regional differences in the combined effects of FDI on carbon emission performance, and the driving effec
