This paper summarized and analyzed the scope of carbon emission accounting in industrial parks and the decoupling relationship between carbon emission and economic development in industrial parks based on one-dimensional or two-dimensional decoupling models,and discussed the influence of va-rious factors on the decoupling relationship in the decoupling effect model based on LMDI decomposition method and Tapio decoupling model,with a view to providing reference for carbon emission inventory es-tablishment,decoupling degree analysis,driver identification and comprehensive assessment.On this ba-sis,it is suggested that industrial parks should formulate a carbon emission inventory reasonably,consider carbon emission drivers in multiple dimensions and build a more comprehensive indicator system.
