In order to better implement the “Two Districts Construction” work plan in Beijing，the depth and breadth of digital trade statistics research should be further improved. This report discusses the definition of digital trade and the attempts made by representative institutions at home and abroad for digital trade statistics，and based on this，the Beijing digital trade measurement work is carried out. Specifically，the first is to use the definition of the extension of digital trade in the “Central Product Classification System”（CPCVer 2.1）as a benchmark，and compare it with the “Extended Classification of Balance of Payments Services（EBOPS 2010）” to make an interface，and calculate the scale of “digital” service trade in Beijing’s through the interface. Second，the concept of “digitized rate” was innovatively proposed. According to the matching results of EBOPS 2010 between 9 digitalized service industries defined by the United Nations Conference on Trade and Development（UNCTAD），the “digitized rate” of each industry was calculated through the investigation of typical enterprises. Based on the “digitalized rate” of each industry and the corresponding “digitable” service trade scale，the “digitalized” service trade scale of Beijing is calculated. On the one hand，this report combines the measurement results to analyze the development of Beijing’s digital trade. On the other hand，it summarizes the difficulties encountered in the survey and measurement，and tries to put forward countermeasures and suggestions from the aspects of promoting the improvement of the digital trade statistics system and improving the level of digital trade statistics.
