The impact of climate change on agricultural quality development under the constraint of China's "Double Carbon" target has been widely discussed by policy practitioners and academic theorists. This paper attempts to deconstruct the logic of how climate change affects agricultural total factor productivity (TFP) in three dimensions—the structure of agricultural input factors, the change in the cropping system, and the stability of crop supply. This paper also reveals the mechanism through which biased technological progress increases agricultural TFP by weakening the magnitude of climate change and empirically tests it by using China's provincial-level data from 2000 to 2021. This study showed that average annual temperature and annual precipitation had significant negative effects on agricultural TFP, that the number of sunshine hours had a significant positive effect on agricultural TFP, and that obvious regional differences existed in the effect of climate change on agricultural TFP. Further mechanism tests revealed that biased technological progress positively moderated the effect of climate change on agricultural TFP. Based on these findings, the appropriate countermeasures for improving climate early warning mechanisms, promoting the progress of appropriate technology, and fostering new agricultural management bodies.

The observed low level of information and communication technology (ICT) usage among micro, small, and medium-sized enterprise (MSME) firms in many African countries may serve as a major constraint to their productivity. The productivity of service and manufacturing firms is impacted differently due to this low uptake of ICT. This paper seeks to examine the differential effects of ICT on MSMEs' productivity in emerging African economies, specifically Egypt and Nigeria. This study evaluates the effects of ICT on MSMEs' productivity across different sectors (services and manufacturing), by size and aggregated. The estimated results support the positive impact of MSMEs' website presence and use of email on their productivity, though the magnitude varies across different analyses and sectors. This appears to support the differential sectoral impacts of ICT on MSMEs' productivity across countries in emerging markets. Specifically, this study finds evidence for a higher impact of firms' website presence on productivity in the manufacturing sector than the services sector across emerging economies. The study, therefore, recommends that emerging markets economies that want to implement appropriate national technology policies to enhance their firms' productivity should always consider their differential effects on various sectors, as universal ICT policies may not achieve the desired objectives.

To achieve the harmonious development of economic growth and the environment, nations must pay more attention to wastewater treatment and boost efficiency using green technology. This study applies the Malmquist-DEA model to assess the efficiency of green technology innovation in 19 Chinese wastewater treatment companies between 2017 and 2020. In addition, focus is placed on the core wastewater treatment technology of the companies with excellent performance, indicating how wastewater treatment companies may improve their green technology. The results of the study indicate that, first, the overall effectiveness of green technology innovation in companies follows a rising and then decreasing trend. In 2020, wastewater treatment companies' green technology innovation efficiency was around 17.4 percent lower than in 2017. Improving technical progress is the key to boosting the total factor productivity of wastewater treatment companies. Second, based on the Tobit regression, the shareholding ratio of companies has a positive influence on the technical efficiency of companies. Therefore, China should increase innovation capacity and productivity, adopt current sewage treatment technology from overseas, and thus gradually achieve clean sewage utilization and ecological environment management.
