Since the new concept of Territorial Capital was proposed in the late 1990s, more and more regional study scholars apply it to regional economic development research. Relevant research discusses the concept, connotation, types and constituent factors of territorial capital, uses comprehensive indicators or representative indicators to measure territorial capital, and then studies the impact of territorial capital endowment on regional development level and regional development differences, regional economic resilience, regional enterprise development, the effectiveness of regional development policy, etc. Territorial capital is a set of various tangible and intangible assets that are owned and can be exploited by a given region as well as constitute the regional economic development driving force and potential of a given region. It includes traditional and non-traditional elements, tangible elements and intangible elements that promote regional development, which not only expands the research scope and boundary of regional economics. Moreover, it is helpful to better excavate the endogenous driving force of regional development and explain the formation and evolution of the regional development gap. The theoretical framework of territorial capital research has been initially formed, but it is still in the stage of exploration and expansion. The theoretical framework and measurement methods need to be further improved, and the research objects are still concentrated in Europe. At present, the research of territorial capital has not attracted enough attention in China, so territorial capital should be applied to the research of regional economy in China. Based on the scientific description of the spatial distribution and evolution of territorial capital, the law of regional economic development, the cause of regional development difference and the mechanism of territorial capital influencing regional development should be deeply explored. Furthermore, it provides experience and policy inspiration for realizing regional high-quality development and coordinated development.
