韦东奕卖书4天后，两套练习册从他的小店消失了。    REHOBOTH BEACH, Del. -- The Biden administration is designating 31 technology hubs touching 32 states and Puerto Rico to help spur innovation and create jobs in the industries that are concentrated in these areas.President Joe Biden is set to announce the hubs on Monday at the White House with Commerce Secretary Gina Raimondo. “I have to say, in my entire career in public service, I have never seen as much interest in any initiative than this one," Raimondo told reporters during a Sunday conference call to preview the announcement. Her department received 400 applications, she said. “No matter where I go or who I meet with — CEOs, governors, senators, congresspeople, university presidents — everyone wants to tell me about their application and how excited they are,” said Raimondo.The tech hubs are the result of a process Raimondo's department launched in May to distribute a total of $500 million in grants to cities.The $500 million came from a $10 billion authorization in last year’s CHIPS and Science Act to stimulate investments in new technologies such as artificial intelligence, quantum computing and biotech. It’s an attempt to expand tech investment that is largely concentrated around a few U.S. cities — Austin, Texas; Boston; New York; San Francisco; and Seattle — to the rest of the country.The program, formally the Regional Technology and Innovation Hub Program, ties into the president's economic argument that people should be able to find good jobs where they live and that opportunity should be spread across the country, rather than be concentrated. The White House has sought to elevate that message and highlight Biden's related policies as the Democratic president undertakes his 2024 reelection bid. “These Tech Hubs will catalyze investment in technologies critical to economic growth, national security, and job creation, and will help communities across the country become centers of innovation critical to American competitiveness,” the White House said Monday in an emailed statement.The 31 tech hubs reach Oklahoma, Rhode Island, Massachusetts, Montana, Colorado, Illinois, Indiana, Wisconsin, Virginia, New Hampshire, Missouri, Kansas, Maryland, Alabama, Pennsylvania, Delaware, New Jersey, Minnesota, Louisiana, Idaho, Wyoming, South Carolina, Georgia, Florida, New York, Nevada, Missouri, Oregon, Vermont, Ohio, Maine, Washington and Puerto Rico.。8月22日晚，韦东奕的B站账号页面已经看不到他的小店以及此前上架的两套小学、初中数学解题能力训练练习册。不过，目前相关商品链接仍能在B站搜索到，销售店铺是“韦东奕图书”，销量还在继续增加。截至8月23日上午，《小学数学解题训练1—6年级超详细答案视频讲解》已售出超过2万本，相关初中产品也售出1万多本。这套练习册覆盖1至9年级，每个年级一套、每套3册。此前售价分别为39.8元和49.8元。

二 | 按照公开销量和标价粗略计算，两类产品对应的成交金约130万元，但这并不等同于实际收入。

店铺销量截图这场销售发生在4天前。8月18日晚，韦东奕时隔一年更新B站账号，发布视频《一道有趣的数学题》。视频中没有本人出镜，只展示了一道小学四年级数学题及解题方法。

三 | 与此同时，他的B站小店上新了两套数学解题能力训练练习册，商品页面标注“韦东奕主编”，并印有他的名字和照片。北京大学已向媒体确认，上述B站账号确实为韦东奕本人账号。

四 | 练习册出版社龙门书局也对媒体表示，这套图书确实由韦东奕本人亲自主编，内容偏向培优方向，本周刚刚上线，目前龙门书局官方账号以及韦东奕个人账号均有售卖。不过这两套练习册还有其他销售入口。8月18日，韦东奕堂哥韦晶洲、堂姐韦丹青的抖音账号，同步上线了相关数学题视频，并挂出了两套练习册的购买链接。商品店铺同样是“韦东奕图书”。

韦东奕图书营业执照截图公开的营业执照显示，“韦东奕图书”所属公司，是杭州奕数文化产业发展有限公司，成立于2026年5月22日，法定代表人为曹恩铭，注册资金100万元，业务类型为零售。其经营范围包括出版物互联网销售、出版物批发、出版物零售，以及教育咨询、技术开发、数字广告发布、文具用品零售、日用百货销售等。事实上，教师、科学家出版教材、科普书和习题集，是知识传播中常见且成熟的一种方式。知名华裔数学家、菲尔兹奖得主陶哲轩，早在15岁就出版了《陶哲轩教你学数学》，介绍解题策略和数学思维。

五 | 因此，在该练习册上架后，不少网友表示支持，认为这并无不妥。但外界也出现了关于韦东奕本人是否主动参与此次卖书的猜测。自走红以来，在大众认知里，韦东奕是一个专注数学、生活俭朴、与互联网保持距离的数学家。媒体曾报道，他几乎不看电视、没有微信，除了查资料很少上网，爱听收音机，最喜欢的事情就是做数学题。

六 | 2025年6月，他在抖音、B站、小红书等平台开通个人账号，迅速积累千万粉丝，但此后长期没有更新。从公开信息看，围绕这两套练习册，除了出版社官方销售，的确出现了个人账号、亲属账号以及相关公司参与内容发布和商品销售的情况。不过，目前的公开资料还不足以确认这些主体之间的具体关系，也无法判断韦东奕本人在其中扮演什么角色。至于商品为何从韦东奕的B站小店消失，韦东奕本人也尚未公开回应。记者：杨智杰编辑：闵杰运营编辑：王琳
