Abstract
Previous studies have made clear the "emission reduction effect" of industrial agglomeration in industry, manufacturing, and other fields, but few studies have explored its driving effect on carbon emission reduction in animal husbandry, especially dairy farming. Therefore, this study applied the data of dairy farming in 28 provinces (cities and districts) in China from 2004 to 2020. We adopted the life cycle assessment and spatial Durbin model to explore the impact of industrial agglomeration on carbon emissions of dairy farming. We reached the following conclusions: Firstly, there were significant regional differences in carbon emissions from dairy farming Chinese during the investigation period, and the total amount showed a trend of "first increase, then decrease". And there was still great uncertainty in the future carbon emission trend. Secondly, Industrial agglomeration has an N-type nonlinear effect on carbon emissions from dairy farming, i.e., as the level of industrial agglomeration increases, the carbon emissions from dairy farming show a three-stage characteristic of "first increase, then decrease, then increase". The inflection points of the "N" curve were 2.124 and 5.753, respectively. Thirdly, industrial agglomeration had a significant spillover effect on carbon emissions from dairy farming, which was manifested in inter-regional spillover and intra-regional spillover mergers. In general, we focus on the impact of industrial agglomeration on carbon emissions from Chinese dairy farming from the perspective of research, which confirms the nonlinear characteristics of the "emission reduction effect" of industrial agglomeration on Chinese dairy farming. Our group also finds that industrial agglomeration has a certain "adjacent-local" carbon emission reduction effect in the spatial scope. It has important theoretical significance and practical value for expanding industrial agglomeration theory and promoting carbon emission reduction in Chinese dairy farming.
