However, it has not yet become an independent and specific branch, and the diffusion of research is obviously dependent on some high-frequency key words. Diffusion outcomes show that digital divide exists between core institutions and ordinary institutions. Journal citation source is expanding from the outstanding journals to the ordinary and journals of other discipline, indicating that ‘new media’ research in mainland China is a closed system on the whole but appears some opening tendency
