Abstract: Development of the unmanned aerial vehicle (UAV) industry is related to construction of the national defense core capability and establishment of digital low-attitude industry economy. With the gradual deepening of civil-military integration development strategy, UAV industry achieves explosive progress. The deep development of UAV industry is closely related to the construction of civil-military integration level evaluation system. At present, the research on the depth evaluation of civil-military fusion is only at the macroscopic level. Based on the grounded theory and fuzzy analytic hierarchy process, a research model of civil-military deep integration based on microcosmic perspective was established. Firstly, the driving factors of civil-military integration in UAV industry were qualitatively analyzed. Then, the theoretical model of UAV civil-military integration driving factors was determined by data collection, open coding, spindle coding, selective coding and saturation checking. Selective coding and spindle coding of the driving elements were respectively input as four first class indicators and fifteen second class indicators. And the weight of every factor was determined with civil-military integration levels for driving factors on the basis of Delphi method and fuzzy Analytic Hierarchy Process. The presented method was used in military-civilian integration level of three UAV enterprises. According to the analysis results, some opinions on construction of civil-military integration depth development were given. The method presented can also be applied to relevant national competent departments and other industries.
