Not long ago, Zeng Xiaomei, the deputy general manager of Guangdong Origin Intelligent Technology Co., Ltd. (hereinafter referred to as "Origin Intelligence"), got a good news: this year, the annual revenue of the enterprise is expected to grow by more than 30% year on year, and the net profit is expected to grow by 350% year on year. High end CNC machine tools, the main product of Origin Intelligence, were once monopolized by overseas giants. The downward pressure of the global economy is coming, and the efforts to gnaw at the "hard bone" of technology have given Origin a rich reward for its intelligence. Since the reform and opening up, Guangdong, a major manufacturing province, has formed a complete industrial system. Among the 41 industrial categories listed in the national statistics, there are 40 in Guangdong. The strong industrial chain integration ability thus forged has become the "core weapon" made in Guangdong. The independent and controllable supply chain of the industrial chain is a basic skill that must be possessed in building a modern industrial system. Under the background of blocking in the front, pursuing in the rear, swinging in the middle, and difficulties in industrial upgrading, Guangdong's industrial chain consolidation, optimization and upgrading are facing many pressures. Adhering to the leadership of manufacturing industry, Guangdong takes the cultivation of 20 strategic industrial clusters under the guidance of "chain length+chain ownership" as an important driving force, promotes the industrial chain to "supplement, extend, fix and strengthen the chain", and builds a strong breakwater for the supply chain of Guangdong's industrial chain in the tide of anti globalization. The 2022 Industrial Development Report released by the United Nations Industrial Development Organization pointed out that compared with other economies, in the face of the impact of the epidemic, China's expected output loss level is lower and its economic recovery ability is stronger. An important reason behind this is that China has built the most complete and efficient industrial system in the world, thus building the core competitiveness of the world's factories. As a major center of the world factory, Guangdong is a distinctive example. Guangdong's industrial chain competitiveness can be traced back to the reform and opening up. The wave of reform and opening up has made "three processing and one compensation" blossom everywhere in Guangdong. It brings the influence of foreign technology and manufacturing experience to Guangdong, and also makes Guangdong's manufacturing chain more and more prosperous. In 1995, the mobile phone giant Nokia settled in Dongguan, marking the beginning of the Pearl River Delta's march towards the world's smart phone city. In its heyday, Nokia had more than 400 suppliers in Dongguan. It has not only driven the development of large suppliers such as Flextronics, but also prompted many Dongguan electronics enterprises to enter the Nokia supply chain and become the second and third tier suppliers of their Dongguan factories. Dongguan's mobile phone hardware manufacturing and supply system began to improve. With the spillover of Shenzhen's electronic information industry, more enterprises began to enter Dongguan. Huawei, Coolpad, OPPO, vivo, Coobie and other enterprises have made Dongguan mobile phone industry blossom. More importantly, with Dongguan as the center, a super industrial cluster has taken shape: the front-end design and application software development are in Shenzhen, Guangzhou, the complete machine is manufactured in Dongguan, and the related supporting production is in Huizhou, Zhongshan, and Foshan. The Pearl River Delta has a complete mobile phone industry chain. 95% of the components in a mobile phone can be quickly equipped in the one hour commuter circle in Dongguan. From 0 to 1, a smart phone goes through a series of processes such as mobile phone motherboard production (SMT), pre processing, final assembly, testing and packaging, and it only takes 18 hours in Guangdong. Relying on the advantages of the industrial chain, Dongguan's mobile phone production has occupied more than 1/4 of the global market all year round. Growing on open genes
