Abstract
Purpose
The purpose of this study is to investigate the impact of digital agricultural insurance on farmers’ fertilizer reduction technology adoption and explain its main mechanisms, as well as to reveal the heterogeneity of the impact with regard to the production scale and crop type.
Design/methodology/approach
Using the dataset of CHFS-SCAU2021, this study empirically examines the impact of digital agricultural insurance on farmers’ fertilizer reduction technology adoption by Probit model and employ instrumental variables and treatment effect model to address the potential endogeneity bias.
Findings
(1) Digital agricultural insurance can significantly improve farmers’ fertilizer reduction technology adoption and (2) it has a greater promoting effect on the adoption of fertilizer reduction technology compared to traditional agricultural insurance, which still holds after correction of endogeneity bias. (3) Digital agricultural insurance can help promote farmers’ fertilizer reduction technology adoption through decreasing risk aversion, information asymmetry and alleviating financial constraint, while (4) it can only promote the fertilizer reduction technology adoption among large-scale and grain-crop farmers currently.
Originality/value
(1) This study is the first to empirically examine the causal impact of digital agricultural insurance on farmers fertilizer reduction technology adoption. (2) This study construct a comprehensive framework to explain the main mechanisms through which digital agricultural insurance influences farmers fertilizer reduction technology adoption both theoretically and empirically. (3) It also compares the disparities between traditional agricultural insurance and digital agricultural insurance in terms of influence on farmers’ fertilizer reduction technology adoption and proposes the relative recommendations on digital agricultural insurance to help improve farmers’ willingness and behavior of fertilizer reduction technology adoption to promote extension efficiency.

To achieve the dual goals of decarbonization and food security, this paper examines China's carbon footprint reduction in 2050 based on current mitigation strategies.
Abstract
Purpose
To achieve the dual goals of decarbonization and food security, this paper examines China's carbon footprint reduction in 2050 based on current mitigation strategies.
Design/methodology/approach
Considering publications as featured evidence, this study develops an investigation of agricultural decarbonization in China. First, the authors summarize the mitigation strategies for agricultural greenhouse gas (GHG) emissions in the existing literature. Second, the authors demonstrate the domestic food production target in 2050 and the projection target's projected life-cycle-based GHG emissions at the commodity level. Lastly, the authors forecast China's emission removal in the agri-food sector in 2050 concerning current mitigation strategies and commodity productions. The authors highlight the extent to which each mitigation strategy contributes to decarbonization in China.
Findings
Practices promoting sustainable development in the agri-food sector significantly contribute to GHG emission removal. The authors find mitigation strategies inhibiting future GHG emissions in the agri-food sector comprise improving nitrogen use efficiency in fertilizers, changing food consumption structure, manure management, cover crops, food waste reduction, dietary change of livestock and covered manure. A 10% improvement in nitrogen use efficiency contributes to 5.03% of GHG emission removal in the agri-food sector by 2050. Reducing food waste and food processing from 30% to 20% would inhibit 1.59% of the total GHG emissions in the agri-food sector.
Originality/value
This study contributes to policy discussions by accounting for agricultural direct and indirect emission components and assessing the dynamic changes in those related components. This study also extends existing research by forecasting to which extent the decarbonization effects implemented by current mitigation strategies can be achieved while meeting 2050 food security in China.

Abstract
Purpose
This study aims to examine the impact of non-fungible tokens (NFTs’) characteristics on Chinese consumers’ purchase intention towards luxury fashion physical products. It also investigates the mediating role of perceived hedonic value and moderating role of perceived NFT–physical product fit during the buying process.
Design/methodology/approach
A conceptual model combining Stimuli–Organism–Response Model and Theory of Consumption Value was established. A purposive sampling method was adopted to collect data from luxury fashion consumers aged 21–41 who lived in four Tier 1 cities in China. Structural equation modelling and SmartPLS 4.0 were utilized to analyse the 304 valid questionnaires collected.
Findings
The study’s findings indicate that luxury fashion NFTs with four characteristics (NFT scarcity, NFT exclusivity, NFT design aesthetic and NFT novelty) affect Chinese consumers’ purchase intention towards luxury fashion physical products positively, with perceived hedonic value mediating these relationships. Further, perceived NFT–physical product fit moderates the relationship between perceived hedonic value and purchase intention.
Originality/value
This study bridges a gap in investigating the interplay between NFTs as intangible collectibles and tangible products, by stressing the significant role played by NFTs in influencing the purchase intention of luxury fashion products. This paper contributes to an understanding of consumers’ psychological responses and behaviours towards NFTs, providing a new perspective in the study of luxury fashion NFTs in the context of marketing strategy and consumption.

Abstract
Purpose
This study aims to solve the problem of weld quality inspection, for the aluminum alloy profile welding structure of high-speed train body has complex internal shape and thin plate thickness (2–4 mm), the conventional nondestructive testing method of weld quality is difficult to implement.
Design/methodology/approach
In order to solve this problem, the ultrasonic creeping wave detection technology was proposed. The impact of the profile structure on the creeping wave detection was studied by designing profile structural test blocks and artificial simulation defect test blocks. The detection technology was used to test the actual welded test blocks, and compared with the results of X-ray test and destructive test (tensile test) to verify the accuracy of the ultrasonic creeping wave test results.
Findings
It is indicated that that X-ray has better effect on the inspection of porosities and incomplete penetration defects. However, due to special detection method and protection, the detection speed is slow, which cannot meet the requirements of field inspection of the welding structure of aluminum alloy thin-walled profile for high-speed train body. It can be used as an auxiliary detection method for a small number of sampling inspection. The ultrasonic creeping wave can be used to detect the incomplete penetration welds with the equivalent of 0.25 mm or more, the results of creeping wave detection correspond well with the actual incomplete penetration defects.
Originality/value
The results show that creeping wave detection results correspond well with the actual non-penetration defects and can be used for welding quality inspection of aluminum alloy thin-wall profile composite welding joints. It is recommended to use the echo amplitude of the 10 mm × 0.2 mm × 0.5 mm notch as the criterion for weld qualification.
