For a smart phone, in addition to the differences in appearance, price and brand, the core competitiveness of mobile phone is chip performance. Nowadays, in terms of chip R & D and design capabilities, Samsung, apple and Huawei both have ultra-high chip design capabilities, which make them become the top suppliers of global smart phones. However, after Huawei was targeted, the disadvantages of chip design capability but unable to be put into production began to emerge. < p > < p > in early August, Yu Chengdong admitted to the public that Huawei’s high-end chips would become out of print, and the reason for Huawei’s chips going to the end of the world was the US ban. In fact, it’s not that Huawei is weak. You know, if Huawei is replaced by apple, it will have the same effect. Because the United States holds the core technology of chip manufacturing, it has imposed a technical blockade on Huawei by increasing the proportion of related technologies. Since then, it is no longer a secret that Huawei has no chip manufacturing capability. < / P > < p > in today’s fast updating of smart phones, without the support of high-end chips, the performance of mobile phones will decline more than one step. However, the reality is still worrying. Huawei’s high-end chips can not be OEM, and the mobile phone share of the high-end market will be directly eroded, which means that Huawei can only take the second place. Previously, Huawei executives have also said that Huawei, which has lost its high-end chips, has potential substitutes, such as Samsung, MediaTek and Spreadtrum, which can survive the crisis through a third-party chip procurement scheme in the short term. < / P > < p > the problem also appears in the “short term”, because according to media reports, the U.S. Department of Commerce once again revised Huawei’s relevant ban to further restrict Huawei’s access to us technology products. 38 Huawei’s subsidiaries, involving Huawei’s operations in 21 countries around the world, were added to the ban. The ultimate goal of this ban is to completely cut off the overall supply of Huawei’s mobile phone chips. < / P > < p > you should know that before this item is modified, Huawei Kirin chips can not be reproduced, but in theory, Huawei can solve the problem of burning coal by purchasing chip design solutions from a third party. However, if the ban comes into effect, it will mean that Huawei will be cut off from buying chips. In other words, as long as it is the object of the ban and wants to obtain chip products from the supply chain with American technology, Huawei cannot be a purchaser, an intermediary, or an end-user. < / P > < p > to be honest, the ban after the upgrade is really a “dirty trick”. Huawei’s purchase of MediaTek’s chips is actually a helpless move, which has both advantages and disadvantages. The advantage is that it will not make China cut back on the mobile phone business, but the disadvantage is that MediaTek’s chip technology capability is not strong, which will inevitably affect the competitiveness of the high-end mobile phones Huawei has built. If MediaTek fails to help Huawei in the new round of bans, Huawei’s mobile phone business will be in real danger. < / P > < p > previously, it was pointed out that Huawei would supply a large order of 120 million chips to MediaTek, helping it become the largest supplier in the chip field, accounting for more than 38% of the market. However, once the ban is implemented, it is likely that there will be a reversal in the supply of goods from MediaTek to Huawei. < / P > < p > in particular, the response of MediaTek to Huawei’s ban upgrade is even more worrying. According to the domestic media, it will follow the relevant laws and regulations of Global trade, pay attention to the changes of export control rules, and consult legal advisers for legal analysis of the new provisions, so as to ensure that the relevant rules are within the framework. < / P > < p > there is no imaginary support for Huawei, let alone whether Huawei will be cut off in the future. On the contrary, it makes people feel that if it exceeds the necessary limit, it can not become the last backing of Huawei. I’m afraid that in addition to worrying about Huawei’s future, this confused response will make people feel sad. < p > < p > they are both technology enterprises, but they have different business environments. American enterprises such as apple have a fair competition environment in China, while Huawei is not only unjustifiably accused in the United States. Even if it runs out of food soon, the other party still wants to get rid of it. It’s really chilling. At present, we only hope that Huawei can achieve something in the semiconductor field as soon as possible, “de beautification” strategy may be the only goal of Huawei. There is a long way to go.
