Abstract:    The cultivation of enterprises′ technological self-reliance and self-improvement capability is an important support for China to promote the development of Chinese path to modernization through comprehensive innovation. Among them, the upgrading of intellectual property as a complementary asset enabling technology standard is the dominant design, which is a key measure for the formation of enterprises′ technological self-reliance and self-improvement capability. However, the process mechanism is still unclear. This study conducted a single case study based on XCMG, a leading enterprise in the construction machinery manufacturing industry, exploring the mechanism of the synergy between technical standards and intellectual property to promote the formation of technological self-reliance and self-improvement capability. The research found that: (1) the technological self-reliance and self-improvement capability is composed of six elements of capabilities, including independent and leading capabilities in technological innovation, development and competition capabilities in international market, leading and controllable capabilities in institutional rules; (2) technical standards and intellectual property in different dominant design stages has shifted the direction of synergistic from "same track" to "changing track", and the relative speed of their synergistic has evolved from "different speed-same speed -acceleration". heterogeneous synergistic behavior forms synergistic mechanisms such as defense, offense, autonomy, and win-win, which is the process mechanism for building technological self-reliance and self-improvement capabilities; and (3) during the transition process of leading the design phase, the collaborative relative velocity drives the change of collaborative direction, presenting a change of "different speeds constrained by the same orbit - same speed driven orbit change - acceleration leading". This process is the mechanism for upgrading different levels of capabilities and combinations to ultimately form the ability to achieve technological self-reliance and self-improvement. This research has deconstructed the connotation of enterprises′ technological self-reliance and self-improvement capability from the three-dimensional framework of "technological innovation-market development-institutional rules", carried out dynamic evolution exploration of their synergy behavior from a new perspective of the relative speed and direction of synergy, and constructed a mechanism for building and improving enterprises′ technological self-reliance and self-improvement capability based on the synergy of the two, and it will provide important enlightenment for China′s scientific and technological innovation manufacturing enterprises represented by construction machinery to comprehensively promote the development of Chinese path to modernization through innovation.
