How do environmental regulations and financial support for agriculture affect agricultural green development? The mediating role of agricultural infrastructure

AbstractEnvironmental regulations and financial support for agriculture have been respectively proved as important means to break through the dilemma of agricultural green development in China. While their interactive influences on agricultural green development are rarely focused, as well as the mediation mechanism. This paper provides an interactive perspective by exploring the direct and indirect mechanisms affecting the relationship between environmental regulations, financial support for agriculture, and agricultural green development, among which the mediating effects of agricultural infrastructure, are further discussed. Based on the provincial panel data for China from the year 2000 to 2021, this paper constructs a fixed effect model, mediating effects model, and threshold panel model to empirically test the direct and indirect effects of environmental regulations and financial support for agriculture on agricultural green development. The results show that: (1) The full sample of agricultural green development in China shows an M-shaped trend, environmental regulations and financial support for agriculture show spatial and temporal heterogeneity among regions. (2) Environmental regulations, financial support for agriculture, and their interaction all have positive effects on agricultural green development, while their interactive effect is greater. (3) Agricultural power facilities not only significantly mediate the relationship between financial support for agriculture and agricultural green development, but also play a mediating role in the positive effect of the interaction between environmental regulations and financial support on agricultural green development. While rural transportation facilities only significantly mediate the positive effect of the interaction between environmental regulations and financial support for agriculture on agricultural green development. (4) Heterogeneity analysis results show that the effect of the interaction between environmental regulations and financial support for agriculture on agricultural green development is greatest in agricultural optimized developing areas; however moderate developing areas are insignificant. This research contributes to understanding how environmental regulations and financial support for agriculture affect agricultural green development and extends the mediating role of agricultural infrastructure in their relationships.Keywords: environmental regulationsfinancial support for agricultureagricultural green developmentagricultural infrastructure Disclosure statementNo potential conflict of interest was reported by the author(s).Additional informationFundingThis research received financial support from National Natural Science Foundation of China (Nos. 72174076, 72174054, and 71974081); National Social Science Foundation of China (No. 22AGL028), Social Science Foundation of Jiangsu Province (Nos. 21GLB016 and 22GLA007); Special Research Project of School of Emergency Management in Jiangsu University (KY-A-04 and KY-C-05), Postgraduate Research & Practice Innovation Program of Jiangsu Province (KYCX23_3792).
