数字农业对气候灾害脆弱性的影响研究OACHSSCDCSTPCD

Exploring the intrinsic relationship between digital agriculture and climate hazards vulnerability is of great significance for preventing and reducing agricultural economic disasters and stabilizing agricultural development.This paper selected panel data from 13 major grain-producing regions from 2010 to 2019,and used methods such as the cross-sectional break method,gray correlation method for panel data,dynamic spatial Durbin model,and synthetic control method to explore the impact of digital agriculture on climate hazards vulnerability.The results showed that:①The development pattern of digital agriculture was changing from low-value unipolar to multipolar,and the climate hazards vulnerability showed a"south high,north low"distribution feature,which was negatively correla-ted with the two factors.②Digital agriculture could significantly reduce the local and adjacent areas'climate hazards vulnerability.After changing the spatial weight matrix,this conclusion remained robust.③ Taking"pilot projects of agricultural and rural big data"policy as an exogenous shock test,it was found that digital agriculture could still reduce the climate hazards vulnerability of the pilot grain-producing areas.④The information foundation of digital agriculture was the primary factor for digital agriculture to reduce climate haz-ards vulnerability.Grain-producing areas should improve the construction of digital agricultural infrastructure,continue to improve agri-cultural digital technology level to help grain-producing areas respond to climate change and achieve high-quality agricultural devel-opment.
