Spatial-Temporal Pattern and Driving Factors of Carbon Emission Intensity of Main Crops in Henan Province

Agriculture is the national economy’s primary industry, and its carbon emissions (CE) are one of most significant factors influencing environment. As a large agrarian province, reducing emission intensity (CEI) agricultural great practical significance to sustainable development agriculture in Henan province. In this paper, CEI rice, maize, wheat from 2001 2020 18 prefecture-level cities province was calculated, spatial-temporal evolution patterns were analyzed. The Spatial Dubin model used study impact mechanism spatial spillover effect main crops’ CEI. result, following determined: (1) crops showed an inverted “V” shape, whereas geographical distribution oblique “T” shape mainly north west. (2) significantly different under factors. Technical efficiency, openness, urbanization level, production agglomeration, fiscal expenditure negatively structure food industry cost water for forestry positively affect crops. (3) effects technology environmental protection, spread surrounding areas through factor flow, spillover, policy spread. efficiency on protection have demonstrative effect, degree openness has siphon effect. Based research results, we should strengthen extension investment gradually improve technical efficiency. be financially supported by government. We will actively promote optimization grain promoting orderly urbanization, strengthening sharing among regions,
