The adoption of sustainable intensification practices (SIPs) is generally lagging in China, as disseminating new technology to millions of farmers on heterogeneous smallholdings is challenging. Agricultural development strategies emphasise the role of new agricultural business entities (NABEs) in driving smallholder farmers' development. This study used a sustainable intensive apple culture system as an example of an SIP. To understand the effects of different information dissemination channels, extension service attributes, social networking structures, and socioeconomic factors on the efficiency of acquiring information on SIPs by NABEs, we used the censored least absolute deviation to analyse the data obtained from face-to-face interview surveys of 218 NABEs in the Loess Plateau. This study found that direct connections between NABEs and research institutions had the strongest facilitating effect on information acquisition, farm shops had the second strongest effect, agricultural extension agencies had the weakest effect, and field agricultural material promotion workers showed a significant adverse effect. Improving the quality of extension services has a far greater effect on facilitating the acquisition of information on SIPs than does increasing extension intensity. Relying primarily on weak ties to manage plantations significantly facilitated information acquisition, whereas relying on strong ties to manage plantations significantly inhibited acquisition. The study results show that implementing the "research institute + NABEs + smallholder farmers" technology extension model can significantly improve the adoption efficiency of SIPs.
