They include not only industry giants such as BMW, Kaspersky, Alibaba and Tencent but also startups that are leaders in some areas of information technology.
A particular highlight is e-commerce innovator Alibaba's take on the future of offline shopping. Its T-Mall-branded unattended supermarket allows shoppers to grab what they like off the shelves after scanning a QR code on entry, with payment being deducted automatically via Alipay once the shopper leaves.
With no cashiers or waiting in line, it is like picking food and groceries from your own cupboard at home.
In a corner of one of the many innovative zones at the expo, the E-Take driverless car gleams in sunburnt orange emitting a similar style and panache to that of a European sports car.
Developed by Zhejiang Hozon New Energy Automobile, the car is making its debut in Wuzhen and many visitors are keen to find out more about the future potential Tesla rival. A spokesperson for the company said that development to bring the car to the market is progressing well and that its artificial intelligence technology and facial recognition give it a competitive edge.
Smaller in stature but no less impressive in ambition, is the XiaoYi interpretation device developed by iFlyteck, a Hefei-based State-owned software enterprise dedicated to the research of intelligent speech and language technologies.
The futuristic device makes real-time translation and interpretation a reality. Speak English into it and it will instantly interpret what you've said into many languages including Chinese, Spanish, Korean or Japanese and vice versa.
"The machine can be put in a pocket and connected to the internet with a cellphone SIM card," said Liu Weiwei, marketing manager of iFlytek.
Ofo, a leading bike-sharing company based in Beijing, was present and also has been working on new technology to benefit customers. "We are trying to make things even easier," said Li Bofei, a business manager for the company.
Ofo, working with Huawei Technologies Co, has introduced a smart bicycle lock that can be unlocked with a smartphone using near-field communication technology, which is "even easier than scanning a QR code", Li said.

This year, the company is exhibiting a smartphone it developed with a button on the back to make things simpler and easier for elderly users who have trouble with regular smartphones. It allows them to connect to the company's internet hospital platform, which it developed in late 2015, and also has all the functions of a regular phone, said Hou Dan, a marketing manager from We Doctor.
China's leading bicycle-sharing service provider, Mobike Technology, was one of the companies given an award for its dockless bike-share system. Mobike built the world's first large mobile Internet of Things (IoT) platform, combining IoT, cloud computing, big data, and artificial intelligence (AI).
As of October 2017, Mobike had entered more than 180 cities in nine countries, with more than seven million smart bicycles and 200 million global users, who complete 30 million trips per day.
Microsoft's Xiaoice, an emotion computer-based AI product, also was presented at the event. It was invented in China and has been promoted in five countries.
Xiaoice has played various social roles by taking different "jobs", such as a TV host, radio host, news commentator and column writer. It published a poetry collection in May this year.
BeiDou Navigation Satellite System (BDS) was spotlighted for its "Chinese solution", which was independently constructed and operated by China and provides service worldwide.
Thanks to the BDS, more than 10,000 fishermen have been rescued, and the major car accident rate and casualty rate have decreased by 50% in China.
