Abstract: As an economy derived and evolved from transportation， Luyan economy is a new economic development model that integrates transportation with related industries such as cultural tourism， modern agriculture， industrial parks， modern logistics， and digital economy. It is an inherent need to implement the strategy of strengthening transportation， build a comprehensive threedimensional transportation network， and form an interactive pattern of integrated development between the main highway industry and related industries. The main manifestations are: insufficient systematic research on Luyan economy in China; Chinas transportation business model tends to be traditional; Chinas road industry has a single economic format; Chins economic integration with road derivatives is not deep; the economic conditions of road transportation in China are not strong. This article constructs a driving force model of the Luyan economy， analyzes and studies the development trend of the Luyan economy in Guizhou province as a typical case， and explores the optimal path for highquality development of Luyan economy in China based on the experience of Luyan economic development in Guizhou province.

摘要： 路衍经济作为依托交通运输派生和演变产生的经济，是交通运输与文化旅游、现代农业、工业园区、现代物流、数字经济等相关产业融合的新经济发展模式，是践行交通强国战略、建设综合立体交通网、形成公路主业与关联产业融合发展互动格局的内在需要。我国对路衍经济的系统性研究不足，交通运输经营模式偏向传统，路衍经济业态单一，对路衍经济融合不深，路衍经济条件不强。构建路衍经济的驱动力模型，以贵州省路衍经济发展态势为典型案例展开分析研究，并立足贵州省路衍经济发展的经验，探索我国路衍经济高质量发展的优化路径。
