On April 8, the annual National Hardware & Electromechanical Industry Exhibition was held in Shenyang. At the opening ceremony, Lu Shijia, the organizer of the organizer of Liaoning Province and Shenyang Hardware and Electromechanical Industry Chamber of Commerce, proposed that the time for the transformation and upgrading of the Liaoshen Hardware and Electromechanical Industry has arrived. As an industry leader, Lu Shijia said that with the rapid development of Shenyang's equipment manufacturing industry, traditional husband and wife stores and father and son stores have been unable to meet the service package of this modern manufacturing industry. So how should the hardware and electrical industry transform to adapt to this development? At the end of 2009, Liaoning Province and Shenyang Hardware and Electromechanical Industry Chamber of Commerce established a group company based on 8 shareholders. Later, with the support of the provincial and municipal governments, the company is preparing to upgrade and transform the traditional hardware and electrical industry business format. Under the active promotion of the Chamber of Commerce, a new high-level and high-standard hardware and electromechanical project will be launched in Shenyang Economic and Technological Development Zone. Lv Shijia, president of the Chamber of Commerce of Hardware and Electromechanical Industry of Shenyang City, Liaoning Province, introduced that the Electrical and Mechanical Equipment Science and Trade City project will focus on introducing and developing headquarters economic, financial, product display, industrial design, Internet of Things, modern logistics and other services. Moreover, in the access mechanism, it is very strict. Only a group of members with integrity qualifications and influential brands in the industry are eligible to enter. This is a good opportunity for industry reshuffle and upgrade, and it must be for the entire hardware and electromechanical industry. The benign development has greatly promoted the promotion.
