中国现代四大发明一般指新四大发明，所谓“新四大发明“是指“高铁、扫码支付、共享单车和网购”。2017年5月，来自“一带一路”沿线的20国青年评选出了“中国的新四大发明”：高铁、扫码支付、共享单车和网购。
1、High-speed rail
On October 1, 1964, Tokaido Shinkansen Line was officially opened to traffic. The operation speed is as high as 210 km/h. So the first real high-speed railway in the world was invented by Japan. This marks the arrival of a new era of high-speed railway in the world.
As a pioneer of high-speed railway in the world, Japan has accumulated rich experience for other countries, including China, which have not yet developed or are developing high-speed railway, and transferred some technology to these countries to help them develop high-speed railway system faster and more conveniently.
In March 2006, the CRH2A train Retrofitted from E2 series 1000 sets sailed from Kobe Port to Qingdao, China, and transferred some technology to China, thus ushering in the era of high-speed railway in China.

1、高铁
1964年10月1日，日本东海道新干线正式通车。运营速度高达210公里/小时。故世界上第一条真正意义上的高速铁路由日本发明。这标志着世界高速铁路新纪元的到来。
日本作为世界高速铁路的先驱为包括中国在内的其他尚未或正在发展高速铁路的国家积累了丰富的经验，并有偿转让了部分技术予这些国家，以帮助其更快、更方便地发展高速铁路系统。
2006年3月，由E2系1000番台改造而来的CRH2A型列车从神户港装船出发前往中国青岛，并转让部分技术予中国，由此开启了中国的高铁时代。
2、Sweep Payment
The scanner payment model is based on the concept of mobile payment, and the earliest batch of payments made by mobile devices occurred in Finland in 1997. Finnish local media reported that Finland Telecom has launched a service to operate jukeboxes and beverage vending machines by dialing a pay phone number, which can buy Coca-Cola at Helsinki Airport.
The scanned two-dimensional code was invented by Japan DW Company in 1994.
2、扫码支付
扫码支付的模式建立在移动支付的概念上，而最早一批由移动设备完成的付款发生在1997年的芬兰。芬兰当地媒体报道，芬兰电信启用了通过拨打一个付费电话号码来操作点唱机和饮料自动售货机的服务，这项服务可以在赫尔辛基机场买可口可乐。
扫描的二维码则是1994年由日本DW公司发明。
3、Shared bicycle
As early as 1965, Amsterdam Municipal Government of the Netherlands put forward the "White Plan", according to which 50 bicycles were purchased by the government and painted with white paint and scattered around the city for people to use.
This is the earliest unmanned shared bicycle system in the world, so the shared bicycle was invented by the Netherlands. In 2007, France also had the freedom of bicycle travel. Later, it became popular and innovative in China, and promoted overseas.
3、共享单车
早在1965年，荷兰的阿姆斯特丹市政府提出了“白色计划”，根据该计划由政府购置50辆自行车并将其刷上白漆作为记号散放在城市各处供人使用，这是世界上最早的无人管理的共享单车系统，故共享单车由荷兰发明。2007年，法国也有单车自由行，到后来才中国风靡和创新模式发展，并推广海外。
4、online shopping
Online shopping belongs to the category of electronic commerce. In 1979, British Michael Aldrich invented the concept of online shopping. Aldridge used a technology called Videotex to connect ordinary televisions to local retailers'computers over telephone lines.
By the 1990s, after Amazon and eBay launched their websites in 1995, e-commerce began to be popular around the world.
4、网购
网购属于电子商务的范畴。在1979年，英国人麦克·奥德里奇（Michael Aldrich）发明了网上购物的概念。奥德里奇利用一种被称为Videotex的技术，通过电话线将普通电视机连接到了当地零售商的电脑。
到20世纪90年代，亚马逊和eBay在1995年推出了他们的网站后，电子商务开始在全球流行。

1、中国古代四大发明
四大发明，是关于中国科学技术史的一种观点，是指中国古代对世界具有很大影响的四种发明，是中国古代劳动人民的重要创造，是指造纸术、指南针、火药及印刷术。
此一说法最早由英国汉学家艾约瑟提出并为后来许多中国的历史学家所继承，普遍认为这四种发明对中国古代的政治、经济、文化的发展产生了巨大的推动作用，且这些发明经由各种途径传至西方，对世界文明发展史也产生了很大的影响。
2、历史意义
造纸术的发明：为人类提供了经济﹑便利的书写材料，掀起一场人类文字载体革命。
雕版印刷术的发明：大大促进了文化的传播。
