Waste source separation requires effort from each individual citizen. As the important drivers of change and potential influencers of the future world, younger Chinese’s waste separation behaviour is crucial to the long-term successful implementation of China’s MSW separation policy. To explore the waste separation behaviour of younger Chinese and identify the factors that may influence their behaviour so as to better encourage younger generation of Chinese to practice waste sorting in their daily lives, a questionnaire survey of 579 primary and middle school (PMS) students aged between 6 and18 years old (y/o) was carried out in Yingtan City, Jiangxi Province, China. Binary logistic regression was adopted to explore the factors that might influence the respondents’ waste separation behaviour. The results indicate that more than half PMS students in Yingtan have participated in waste separation, and junior year students perform better in waste separation practice than their seniors. Students are found to have basic knowledge of MSW classification, but they are more familiar with recyclable waste and hazardous waste than non-recyclable waste. The analysis also highlights positive relationships between PMS students’ attitude to waste separation, their willingness to do it, their environmental education and their waste separation behaviour. The level of convenience of waste sorting facilities and influences from friends and families are also positively related to the students’ waste separation practice, but families have the strongest influence. The perception of a mandatory waste separation policy would demotivate students in terms of waste separation practice, while giving rewards is considered to be the most effective approach to encouraging waste separation. Finally, management strategies for improving PMS students’ waste separation behaviour are discussed and several recommendations for improvement are made.

Technology includes hard technology and soft technology. Material technology embodied in production conditions and working conditions such as machinery, equipment and infrastructure is called hard technology, referring to the technology directly used in the development and production of means of production and means of subsistence, such as product design technology, equipment manufacturing technology, etc. Non-material technology, which embodies the experience, skills and management ability of process management, decision support and information technology, is called soft technology. Hard technologies make things easier and faster, while soft technologies promote flexibility and creativity. However, hard technologies take time to produce and have negative environmental impacts, while soft technologies are simple to produce but hard to use. Hence, finding the right balance between hard and soft technology investment is important for the sustainable increase of productivity. In recent years, China has continuously increased its investment in science and technology in aquaculture industry. However, the majority of the investment has gone to hard technology, which has hampered the long-term development of the industry. This paper aims to look at the status quo of the scientific and technological progress of the aquaculture industry in China and explore how the advancement of hard and soft technologies play a role in the economic growth of the aquaculture industry. Transcendental logarithmic production function is employed to calculate the contribution rate of technological progress on China’s aquaculture industry, and the contribution rates of hard technologies and soft technologies are examined separately. The results indicate that, from 2012 to 2020, the contribution rate of overall technical progress on aquaculture in China was 80.159%, of which 71.720% came from the progress of hard technologies, while only 8.439% came from the progress of soft technologies. Based on this conclusion, the paper calls for a balance of hard and soft technologies in the aquaculture industry in China to ensure a healthy and sustainable aquaculture industry. Policy suggestions are also put forward.
