Abstract The integrated development of the industrial chain and the innovation chain is of great significance for China to achieve high-level scientific and technological self-reliance. For a long time, research on the integrated development of the innovation chain and industrial chain has generally stayed at the macro level, the industry level, or a specific link of the industrial chain innovation chain, and thus the specific level of their integration, especially the integration within and between industries is obscure.#br# On the basis of the patent data in PATSTAT database and China's classification of strategic emerging industries, this study builds a more scientific and reasonable double-strand fusion index system from three perspectives: innovation basic ability, intra-industry innovation network and inter-industry innovation network, and explores how innovation chain and industrial chain are integrated and the specific level of integration development from the micro level to find out the deep-seated mechanism and law of double-strand fusion development more clearly. In this paper, the reference table of strategic emerging industry classification and international patent classification (2021) (Trial) issued by the China National Intellectual Property Administration is used to construct the industrial patent matching data, and the industrial classification code is related to the patent through the patent IPC mapping relationship in PATSTAT, and it is used as the basic data for subsequent research. A detailed comparison between China and some OECD countries' industrial chains and innovation chains' integration is made by first analyzing the innovation basic capability index, intra-industry innovation network index and inter-industry innovation network index, and then the development index of double-chain integration of various economies. It is found that, in terms of innovation basic capability index, China has caught up with the OECD average level and is slightly higher than the United States, Japan and South Korea, but significantly lower than Germany; in terms of intra-industry innovation network index, China has achieved a great leap, but it is still lower than the United States and Germany; in terms of inter-industry innovation network index, China has risen rapidly, surpassing the average level of OECD, and now it is only behind the United States (but with a big gap) and slightly higher than Japan; in terms of integration index, it is very close to Germany at present, slightly higher than the average level of Japan, South Korea and OECD, but the gap with the United States is obvious. On the whole, the level of China's double-stranded integrated index has been greatly improved in the past 30 years. At present, it is comparable to Japan, higher than the average level of South Korea and the OECD, but still lags behind the United States and Germany. There are still some gaps compared with the global leading levels in some fields, and deficiencies in the construction of intra-industry technology networks and inter-industry technology interaction. The development of double-stranded integration faces risks including intermediate sources, middle income traps, export channels, internal circulation systems and value chain dominance. #br# In order to accelerate inter-industry and intra-industry integration and innovation and jointly promote the integration and development of the industrial chain in the innovation chain, it is first of all essential to focus on key technologies in core fields, enhance the control of the commanding heights of the double chain,strengthen the research of cutting-edge technology, promote future industrial development, and build an efficient industry-university-research cooperation platform to give full play to the functions of resource integration and achievement transformation. Second, efforts should be made to promote inter-industry integration and innovation, guide the industrial chain to drive the development of the innovation chain, strengthen cross-industry technology integration and innovation, further promote the development of "manufacturing+service" integration, and the organic integration of new elements and traditional elements. Third, it is necessary to promote complementary innovation among regions and the supporting role of the innovation chain in the industrial chain, handle the relationship between regional layout and regional coordination, inter-industry and intra-industry, formulate innovation policies focusing on technology clusters for different regions, and form a multi-dimensional, three-dimensional and complementary technological innovation pattern between regions, industries and intra-industries.#br#
