Improve the ability of quick response

　　 Lin Yunfeng, President of China Knitting Industry Association This paper introduces the economic operation of the knitting industry in the first half of 2022, based on the work of the association, and analyzes the development trend and key points of the industry in the second half of 2022. He said that due to the influence of international situation and domestic epidemic situation and other factors, the operation pressure of the industry increased significantly in the first half of the year, the growth rate of scale continued to slow down, and the profit was under pressure. Taking April as the cut-off point, it bottomed out and recovered. The domestic market is still sluggish, the export performance is better than expected, and the development recovery foundation needs to be stable.

"At present, enterprises should strengthen the awareness of risk prevention and control, maintain the stability and healthy cash flow of the supply chain, especially increase the strength of scientific and technological innovation, improve the added value of products, accelerate the application of digital technology, reduce costs and increase efficiency, practice internal skills, improve the rapid response ability and self competitiveness to cope with external uncertainty." In view of the trend prediction and response measures of the knitting industry in the second half of the year, he said that with the continuous improvement of the domestic epidemic prevention and control situation and the acceleration of the implementation of a package of policies and measures to stabilize the economy, the domestic sales market will gradually come out of the trough and the quality and efficiency of the industry will gradually improve; In terms of export, the market demand of the major economies in Europe, the United States and ASEAN is still strong. Combined with the effectiveness of RCEP agreement and the depreciation of RMB exchange rate, the export of the knitting industry is expected to maintain a rapid growth in the second half of the year, and the annual export volume is expected to exceed 100 billion US dollars again.

Facing the future development of the industry, he stressed that the focus of high-quality development of knitting will still focus on scientific and technological innovation and green manufacturing. Technological innovation promotes industrial upgrading It is necessary to establish a collaborative innovation mechanism of industrial chain and pay attention to the cross integration and cross-border cooperation of advanced technologies; Speed up the pace of digital transformation of the industry, improve the flexible manufacturing and rapid response capabilities of enterprises, reduce costs and increase efficiency. Green development leads advanced manufacturing Under the dual promotion of "post epidemic" and "double carbon target", we should accelerate the adoption of new technologies, new equipment and new processes, promote green management of product life cycle, and develop low-carbon circular economy. Among them, it is necessary to establish a sustainable development ecosystem, promote efficient recycling of resources, and lead and advocate green consumption.
