回顾《近代中国》创刊以来的50年,我们可以看到,肇始,在《近代中国》所有作者中,非华裔美国学者占比最大,为73%,到20世纪末,占比仍然高达64%,但之后则直线下降,2005—2009年为26%,2020—2022年为11%。在一定程度上,这样的趋势被在美国华裔学者(无论美国公民与否)的扩增部分抵消。近20年中国内地学者在学刊上的发文占比越来越大,如今达到28%。如果再加上美国和全球其他地区华裔学者的话,占比更高达65%,无疑乃是重大的演变。同时,在美国以外的其他地区(诸如英国、加拿大、澳大利亚、德国、荷兰等)的非华裔中国研究专家有一定比例的扩增,但总体来说,英语中国研究近乎是以华人为主的天下,也是一个高度跨国化的专业。在回顾与总结之外,本文将附带一些给青年投稿者的建议。
