《区域全面经济伙伴关系协定》(RCEP)的生效实施推动亚太区域经济一体化建设迈入了新阶段。文章采用2005—2021年中国数字产品出口数据,从出口规模、出口结构和出口技术复杂度等维度对中国出口RCEP伙伴国数字产品的新特征进行了深入分析,结果发现,中国数字产品出口规模不断扩大,出口产品技术含量也有所提升。但同时中国数字产品的出口结构有待进一步优化,在产品结构上偏向于信息通信技术服务和其他商业服务,高附加值的金融服务、知识产权服务等领域的出口规模相对较低;在地区结构上高度集中于日本和新加坡,对其他东盟国家的数字产品出口量偏低。此外,中国数字产品出口还面临数字核心技术“卡脖子”、数字产品贸易保护规则不完善等诸多新挑战。因此,未来中国应以RCEP生效实施为契机,从促进数字产品出口升级,推动数字核心技术革命性突破,共建数字贸易规则、完善数字产品安全保障体系等多方面入手,全方位推动中国数字产品高质量出口。

A set of homogenized monthly mean surface air temperature （SAT） series at 32 stations in China back to the 19th century had previously been developed based on the RHtest method by cao et al., but some inhomogeneities remained in the dataset. The present study produces a further-adjusted and updated dataset based on the Multiple Analysis of Series for Homogenization （MASH） method. The MASH procedure detects 33 monthly temperature records as erroneous outliers and 152 meaningful break points in the monthly SAT series since 1924 at 28 stations. The inhomogeneous parts are then adjusted relative to the latest homogeneous part of the series. The new data show significant warming trends during 1924-2016 at all the stations, ranging from 0.48 to 3.57℃ （100 yr）^-1, with a regional mean trend of 1.65℃ （100 yr）^-1 ; whereas, the previous results ranged from a slight cooling at two stations to considerable warming, up to 4.5℃ （100 yr）^-1. It is suggested that the further-adjusted data are a better representation of the large-scale pattern of climate change in the region for the past century. The new data axe available online at http：//***/10.11922/sciencedb.516.
