At the beginning and end of the year, it is often a small peak for mobile phone manufacturers to offer discounts and promotions. This year, in addition to other manufacturers, consumers have also received official "benefits". Recently, the National Development and Reform Commission announced that it will provide subsidies to individual consumers for purchasing three types of digital products, including mobile phones, tablets, smart watches, and wristbands. The focus of "trade in" has shifted from the two major fields of automobiles and home appliances to consumer electronics, sparking heated discussions among consumers. The expansion of "trade in" is targeted at the domestic market environment, and compared to automobiles and home appliances, the three major digital products have a more positive significance in "trade in". Firstly, the three major digital products are the emerging advantageous industries in China. As early as more than ten years ago, China carried out the "trade in" of household appliances and cars. At that time, the manufacturing of household appliances and cars in China was in the early stage of its rise, while the tide of digital products had not yet arrived. 3G networks and mobile Internet had just emerged. The "trade in" did not play a significant role in the development of consumer electronics. Nowadays, the market landscape is completely different. Taking mobile phones as an example, data shows that in the first 10 months of 2024, the domestic market shipped 250 million mobile phones, a year-on-year increase of 8.9%; 353 new models have been launched, and China continues to maintain its position as the world's largest single smartphone market. With the expansion of competition and market size, "trade in" will more effectively promote the technological iteration of Chinese digital enterprises. So from the perspective of the industry, the expansion of "trade in" is a targeted support for the high-quality development of the consumer electronics industry. Secondly, a shorter consumption cycle naturally aligns consumer electronics products with the concept of "trade in". The effectiveness of 'trade in' depends on demand, and the service life of household appliances and cars is often over 10 years. The consumer demand created by such products' trade in 'is mostly one-time, making it difficult to create sustainable consumption. Comparatively speaking, digital products such as mobile phones iterate faster, AI、 The development of display and processing technology not only brings about changes in the quality of functional experience, but also constantly increases the demand for device performance in applications. The replacement of hardware often significantly improves the performance of new digital products. Therefore, the consumption iteration time of digital products is about 2 to 3 years, and "trade in" can better meet the purchasing needs of consumers. In addition, due to the strong performance release of previous generation digital products, the iteration period of digital products caused by insufficient performance in recent years is being extended. The "trade in" policy is also an effective way to address this change. Finally, the consumer electronics second-hand goods market and circulation mechanism have also become relatively mature. In fact, although it is a "trade in" policy, the low efficiency and low revenue of old goods recycling have always been the pain points of the "trade in" policy in the home appliance industry. This is because the home appliance industry lacks a sound mechanism for handling old goods, and many appliances worth tens of thousands of yuan have to bear labor and cleaning costs when they are recycled, resulting in low residual value and easily affecting the recycling rate and willingness to replace them. On the contrary, consumer electronics products have an active second-hand market, and some manufacturers themselves are also important participants, such as Apple, which has used "trade in" to recycle Apple phones and extract production materials. Carrying out "trade in" in the digital field can objectively promote consumer electronics manufacturers to actively establish a sound recycling mechanism and take on the social responsibility of recycling and reusing. In the long run, it can not only help manufacturers expand their new strengths in official refurbished machines and waste equipment disposal, but also promote intensive and green development from a social perspective. In the past year, the "trade in" policy has achieved good results. Nearly 2.7 million cars have been scrapped and replaced nationwide, with over 3.1 million replaced. More than 33.3 million consumers have purchased over 52.1 million units of "trade in" home appliances. Nowadays, the "trade in" policy targeting consumer electronics is precisely focusing on the implementation of the "target", pursuing the "maximum effect" of the policy in promoting consumption, stimulating research and development, and building the recycling industry, to achieve the upgrading of the consumer market. Looking ahead to the future, it is expected that the trend of "trade in" expansion will not stop, and will follow the following trends: firstly, continue to expand to industries with comparative advantages in China; Secondly, expanding from hardware to software and from products to services; Thirdly, expanding from labor-intensive and asset intensive consumer goods to technology intensive consumer goods; Fourthly, expand from rigid and durable consumer goods to elastic demand and high-frequency iterative consumer goods.
