Scaling New Heights(HKTDC Electronic Components & Parts, Vol 01,2009)


Hong Kong Electronic Components & Parts


Today's electronic gadgets demand increasingly sophisticated components and parts - a demand that Hong Kong is making tremendous efforts to fill

Hong Kong's electronic components and parts industry is climbing the value chain as companies increasingly invest in R&D and cooperate with research institutes to develop state-of-the-art products for global markets.

These developments take place amid growing competition in the low-value segment and rising demand for better-performing electronic gadgets, and are backed by the local industry's strengths.

"Many companies are now producing precision and high-value products as the industry is going up the value ladder," says Dr Lui Sun Wing, Vice President at The Hong Kong Polytechnic University.

A similar observation is made by Edwin Pun, Chair Professor of the Department of Electronic Engineering at City University of Hong Kong. "Local manufacturers have been more active in R&D in recent years, for example, in the wireless telecommunications and microwave electronic components and products sectors," he says.

Both universities report increased R&D cooperation with local companies and technology transfer to the electronic components and parts industry over the past couple of years. "It's a good thing because universities can both provide expertise and a cost-effective way for companies to acquire advanced technology," remarks Professor Pun.

Ample advantages

The transformation is supported by the sector's strengths and advantages, including its easy access to the huge pool of resources on the Chinese mainland.

At present, many Hong Kong electronic components and parts manufacturers run factories on the mainland to capitalise on the lower costs of production and great supply of land and manpower.

Professor Paul Cheung, Director of Technology Transfer Office at the University of Hong Kong, urges the local electronic components and parts industry to fully integrate with the Pearl River Delta (PRD).

"The benefits of integration would be enormous," he says. "Most of the world's consumer electronic products are now produced in southern China, where the electronic components and parts industry is also doing well - Shenzhen, for example, is strong in terms of both talent and product variety."

Professor Cheung suggests that local industrialists should tap the region's vast resources. "It is impossible for Hong Kong to become a big manufacturing base on its own - there is simply not enough land or people," he says.

"That's why, when mapping out its direction and strategy, the local industry must at least see itself as part of the PRD - if not the entire Guangdong Province."

Solid strengths

Professor Cheung, however, also highlights Hong Kong's strengths. "The local industry is keenly aware of international trends and market directions," he says, adding that Hong Kong is also good at project management and business administration.

In addition, he maintains that Hong Kong has the best universities in southern China, which are up to world standards in terms of R&D achievements. "Therefore, we must compete on innovation and technological advancement," asserts Professor Cheung.

He believes Hong Kong may specialise in technology development, pointing to the competence of local firms in identifying market needs and finding the right talents to create solutions to electronic components problems.

This sentiment is shared by industry leaders such as Roy Chung, Chairman of the Hong Kong Trade Development Council's (HKTDC) Electronics/Electrical Appliances Industries Advisory Committee (EEAIAC).

"Hong Kong's electronic components and parts industry is backed by the mainland and facing the world," says Mr Chung. "We can join hands with the mainland to conduct R&D and use it as a base to produce and sell while also selling to other parts of the world."

With such solid strengths and advantages, Hong Kong's electronic components and parts industry looks set to scale new heights in product development in the years to come.

Astounding achievements

Hong Kong's electronic components and parts research focuses on design of high-end products, including:

  • sophisticated ICs and ASIC (application-specific integrated circuit) chips
