In order to find Taiwan's next star industry, key technologies and new business opportunities, the "Looking at the 2017 Industry Development Trend Seminar" organized by the Industrial and Economic Research Center of the Industrial Technology Research Institute (IEK), which is based on the "digital economy" The proposal of industrial model transfer and economic model innovation driven by "digital technology" and the development of emerging technology from the global "future industry" demand, and a series of industry reviews and prospects, In particular, the following key issues have been discussed for key industry issues such as "electronic components and displays":

(1) In 2015, Taiwan connector manufacturers benefited from the emergence of Type C new specification connector requirements and manufacturers' transformation of connectors in non-3C applications. The annual output value is still 0.8% higher than last year. The growth rate reached NT$171.3 billion. Looking forward to 2016, with the launch of new 3C products, the continued growth of the IoT market and the penetration rate of Type C connector applications, it is expected to drive the output value of the connector to NT$177.2 billion, representing 3.4% of the year. growth rate.

(2) Looking into the future, ITRI believes that the global component market will be driven by the demand for smart phones, and will reach its peak growth in 2015, and the growth of market size in 2016 will tend to ease. Taiwan's electronic components are mainly exported to the Chinese market, while the United States and European countries are the bulk of the consumption of end products. The trend changes in these three regions are the key factors affecting the changes in the output value of Taiwan's electronic components industry. At present, export orders for electronic products in mainland China continue to be affected by the active expansion and competition of the red supply chain. The European and American consumer markets (especially in Europe) continue to face the pressure of weak overall demand. Therefore, the pressure of future industrial competition will naturally be Increase without decreasing. Accordingly, the focus of the development of Taiwan's component industry in the future will focus on a variety of next-generation end-product technology, energy-saving and new-energy vehicles, and how to master the key components required for such niche-type products? It will be the next wave of opportunities for the transformation of Taiwan's electronic components industry. Secondly, automotive electronics and industrial applications have the advantages of growth and high gross profit. The industry of Taiwan related industries should be moderately transformed and diversified to maintain the competitiveness of products.

In the past ten years, for many Taiwanese manufacturers entering the connector industry, the connector industry has been regarded as a profitable and high gross margin industry. The main reason is the high and low in the connector industry. The technology used in the order connector products is quite different. This technically different feature makes the positioning of related products between international manufacturers and Taiwanese manufacturers extremely clear and clear. In addition, due to the international manufacturers For all kinds of connector products that are commissioned, it is required to have a wide range of application capabilities. This demanding product requirement also forces Taiwanese manufacturers who have commissioned OEMs to have different specialization projects, thus avoiding subsequent contacts. The Red Sea (Chinese related manufacturers) is competing. However, in recent years, with the gradual changes in the international situation and industrial situation, Taiwanese manufacturers have begun to face the critical opportunity to change their business strategies in response to changes.

However, as far as the past of the Taiwan connector industry is concerned, in fact, as far back as 2008, the relevant Taiwanese manufacturers that use connectors as the main products of the production line have already I felt and experienced an industrial crisis. At that time, many Taiwanese manufacturers clearly realized that they only depended on the PC industry, and they were very vulnerable to the dilemma of the PC industry, low barriers to entry, and fierce competition in the industry, which led to a crisis of survival that could not continue. Therefore, At that time, all relevant Taiwanese manufacturers almost adjusted accordingly in their business strategies, and they were able to use the multi-transformation strategy to cover the application aspects of connector products to communication or consumer electronic products, such as mobile phones. With game consoles...etc. Accordingly, Taiwanese manufacturers, which originally relied heavily on connectors for computers and their peripheral devices, have transformed into niche connectors used in the development and production of various consumer electronic products or displays for nearly a decade.

However, as mentioned above, the 2008 financial turmoil has indeed broken the industry tacit or unspoken rules that have long been followed by many players in the connector industry, such as the US, Europe and Japan that originally produced high-end or high-end technology connectors. Connector manufacturers, under the reality of the growing shortage of profits, also considered the production of low-end connectors, and seriously invaded the main product line that Taiwan connector manufacturers have mastered for many years. Faced with this situation change, In addition to the need to speed up the pace of business management strategies, Taiwan's connector manufacturers must add new points to the new strategy that can be considered in the past, and explore, develop and improve the future characteristics of connectors. Producing more and better connector products that meet market needs, can now occupy a place in the market.
