Method and device for evaluating emission change and emission contribution of carbon dioxide

The invention provides a carbon dioxide emission change and emission contribution assessment method and device, and relates to the technical field of carbon dioxide emission assessment, and the method comprises the steps: obtaining target data of a target region in a preset time period, the target data comprising remote sensing image data, meteorological data and attribute data of social and economic characteristic attributes; normalizing the meteorological data to obtain normalized data, and processing the remote sensing image data and the normalized data by using a multiple linear regression model to obtain carbon dioxide emission change data; calculating a carbon dioxide annual emission factor change value of the target area based on the target data and the normalized data; based on the carbon dioxide annual emission factor change value and the attribute data, constructing a random forest model; based on the random forest model, the carbon dioxide emission contribution degree corresponding to the social an
