The results showed that Chinese turbot farming industry had mainly been concentrated in Liaoning and Shandong. The degree of its industrial agglomeration was relatively higher but there was a downward trend.The development of industrial diffusion and aggregation was mainly affected by such factors as natural resources, knowledge, technological innovation, economic policies and market demand. Both the diffusion and aggreg
