我国电子商务近两年呈快速发展的态势,预计2017年中国在全球电子商务中的份额将达到75%,成为"电子商务大国"。与此同时,我国的电子商务立法也提上了日程,然而在目前的电子商务法大纲草案讨论稿中并没有有关电子商务税收的具体建议。原因在于,目前我国就电子商务税收问题相关的数字商品分类、电子商务流转税征管、跨境数字商品交易的税收征管与退税等关键问题尚未形成统一且成熟的意见。美国近期形成的数字商品税收模式对我国颇具启发意义,我国可在此基础上构建自己的数字商品税收规则,进而推动电子商务立法进程。

4只箭毒蛙被快递进境事件又一次给我国的生物安全治理敲响了警钟。新市场或者新交易路线的开发对引进物种有积极的影响,贸易额的增长增加了外来物种在当地传播和建立种群的可能性。随着跨境电子商务的高速发展,异域另类宠物交易有了非常便利的渠道,网络将其源源不断输入我国境内。作为外来物种,异域另类宠物有可能加剧我国外来物种入侵的威胁和隐患,从而危害我国生物多样性和生态安全。而我国目前外来物种入侵相关立法并不完善,多年来我国都无法摆脱遭受外来物种入侵最严重国家之一的头衔,新问题的出现无疑会加剧情况的恶化。对此,我国应升级现有控制手段为立体防御体系,尽早系统化立法,防患未然。
