Small and medium-sized enterprises(SMEs) are facing high fixed costs and risk of low-end locking when upgrading along the global value chains. Thus, it is urgent to take the digital economy as a new engine and a new momentum for their transformation and upgrading. This paper presents the networking effect,cost saving effect, value creation effect and value chain governance effect of the digital economy in promoting the upgrading of SMEs along global value chains and builds a dynamic mechanism for SMEs to start the value chain upgrading. This mechanism covers four major stages, namely, initial connection, all-round development, leap forward and high-level participation. After these stages, the SMEs finally evolve into a leading enterprise in value chains with cutting-edge technology and mature performance in implementation of modular transactions. With reference to the advanced experiences of USA, Germany and Japan in the development of digital economy, this paper puts forward policy suggestions from the following six aspects to propel the upgrading of SMEs in GVCs under the development of China's digital economy, i.e., ensuring digital connectivity, encouraging meta-innovation based on digital technology, implementing competition regulations, promoting e-governmental efficiency, establishing a digital security protection system and building an Internet governance system.
