Abstract:

In the era of information, the organizational form of networks is undergoing profound changes. In this context, the question of the evolution of networks is widespread concerned by many disciplines, such as sociology, management, economics and geography. Explaining the network's long-term dynamic mechanism is one of the core propositions of the economic geography in the field of network evolution. Current economic geography about the network, however, is often limited to a specific space within either a global scale, a national scale, or a local scale, focuses on the interaction between society actors or economic actors within a particular scale and those power, lacks of the research about network expansion phenomena and network evolution dynamic mechanism that network′ actors transferring from the local-scale networks to large-scale networks. The network has a feature geographically scalable, means the network has a local, national, regional, global and other multiple spatial scales. So the aim of this article is to explore the network evolution dynamics across spatial scales. The study is a new attempt in the field of network evolution. Grassroots stars are quality carrier for studying network spatial evolutionary dynamics, which have the process of transferring from local network to regional network, and to national network. The study takes a grassroots star named ZHU Zhi-wen who has become famous in short time in the year 2011 as an example, uses the details of ZHU’s performance trips published in Baidu Encyclopedia and Baidu's online user forum, and explores the network evolution dynamics of a grassroots star’s across spatial scales. It was found that ZHU’s network experienced four network stages, specifically, the first stage is personal relationship network in local scale, the second stage is grassroots star network in provincial scale, the third stage is famous person active network in national scale, and the fourth stage is influence extended network in global scale. Due to the overall popularity of information technology, ZHU spans from local network to national and global network extremely quickly. In this article, key actors, organization, technology and institution are used to build a analytical framework for network spatial evolution. It is believed that the key actors of different scales are directly dynamics for grassroots star across networks; the universal prevalence of information and communication technology especially in villages is an important support for the rapid upgrade; some TV programs of different levels are important driving forces for grassroots star to improve networks status; the implement of policies to aid agriculture and benefit farmers is the root cause of grassroots stars appear frequently. Finally, it was recommended that the country should play the role of systems and platforms to discover useful talents, in order to better serve the building of a socialist country.
