| This study examines the impact of new-type agricultural productivity on integrated urban-rural development and its underlying mechanisms. Utilising panel data from 30 Chinese provinces spanning 2012 to 2021, empirical tests were conducted employing bidirectional fixed-effects models, mediation models, and threshold effects models. Results indicate that new-type agricultural productivity significantly promotes integrated urban-rural development, exerting its effects through two channels: urban-rural factor mobility and agricultural technological innovation, with the mediating effect of factor mobility being more pronounced. Furthermore, the promotional effect of new-type agricultural productivity on integrated urban-rural development is most pronounced in eastern regions, followed by central regions, while its impact is relatively weaker in western regions. Moreover, when using per capita GDP as a threshold variable, the promotional effect of new-type agricultural productivity on urban-rural integration exhibits a non-linear pattern characterised by initially increasing and subsequently decreasing marginal effects. Based on these findings, the study proposes optimising the development pathways of new-type agricultural productivity, advancing urban-rural integration through locally tailored approaches, and strengthening the driving force of technological innovation to promote coordinated urban-rural development and rural revitalisation. |
