According to the input-output table of Fujian Province, and the industry classification standards, the manufacturing and producer service sectors are divided into low-tech, medium-tech and high-tech intensive levels to measure the degree of integration and development of the “two industries”. By constructing the evaluation index system of the integration development of "two industries" and the coupling coordination degree model, the comprehensive evaluation of the integration development of "two industries" in Fujian Province is conducted. The results show that the degree of one-way integration between the "two industries" in Fujian Province is high, the coefficient of influence of manufacturing on producer services is low, and the coefficient of influence of traditional manufacturing is relatively high. Compared with other provinces in the southeastern region, Fujian Province has a relatively high degree of comprehensive integration of the “two industries”. The degree of coupling and coordination in the manufacturing industry is moderate and the degree of development is relatively stable. The degree of development of producer services is low, but the degree of coupling and coordination is on the rise. Overall, the coordination level of the "two industries" in Fujian Province is in the primary coordination stage, and the restrictive factor is the lagging type of producer services.
