Castor design of applications - in daily life

Universal wheel, adjust the foot the link between the manufacturers at home and abroad market, the more closely, two-wheel castor ability due to the global value chain of enterprise upgrading, based on the global value chain of the native production-oriented foreign trade enterprises to upgrade research, foreign trade has grown into an important component of China's gross domestic product (GDP) and domestic important engine of economic growth. In recent years, China's total import and export accounted for about 50% of gross domestic product. Economies has deep into the global value chain system of division of labor. Division of global value chain activities play a bridge of communication at home and abroad and foreign trade enterprises. Especially set production, processing, heavy duty double castor export for the integrated production-oriented foreign trade enterprises is in the dominant position of communication. But in recent years our country domestic production-oriented foreign trade enterprises in the process of inserting into global value chain is also highlights the low production capacity, technology and thin series of problems such as pollution, profit, transformation and upgrading of enterprises become a problem need to solve urgently. This is proposed based on global value chain of the native production-oriented foreign trade enterprises to upgrade research 'research subject. Secondly, dialysis, based on the global value chain of the mechanism of the local production-oriented foreign trade enterprises to upgrade. This article according to its local production-oriented foreign trade enterprises in China have the ability to upgrade the level of divided into lower production enterprise, advanced production-oriented enterprises, innovative enterprises and knowledge-based enterprise four types. When integrated into the global value chain division of labor system, the first two direction of the transformation and upgrade of manufacturing is to reduce costs, improve the production of value-added rate, based on the lateral expansion of global value chain, embodied in the smile curve flattening deformation; Direction of the transformation and upgrade of innovative enterprise's transformation strategy on the global value chain link, to permeate the production of high value-added space, based on global value chain of vertical infiltration, embodied in strategic points on the same smile curve transformation; Direction is the conversion of the transformation and upgrade of knowledge-based enterprise's value chain, from low value-added rate of transition to the amplitude of the value-added value chain, value chain based on global value chain ladder transition, are embodied in the smile curve of from low level to high level smile curve transformation. On the basis of summarizing the existing research results, build a set of local production-oriented foreign trade enterprises in China is based on global value chain upgrade ability evaluation index system. In this paper, by means of analytic hierarchy process (ahp) to calculate the comprehensive weight of each evaluation index for established based on global value chain of enterprise upgrading ability comprehensive evaluation basis of membership degree. Also made clear based on global value chain upgrade ability evaluation of comprehensive membership degree and the corresponding relations between the enterprise type, solved based on the global value chain of the native production-oriented foreign trade enterprises to upgrade ability and the corresponding relationship between enterprise type and upgrade mechanism problem. Revealed based on the global value chain of the native production-oriented foreign trade enterprises to upgrade project implementation timing problem. Enterprise upgrade project execution is usually in the timing of its brings the profit maximization. The timing model of investment options, this paper, the enterprise upgrade project implementation as an investment option with uncertainty, respectively discusses the monopoly and competition conditions of local production in our country foreign trade enterprise implement upgrade options utility maximization of threshold value and the main influence factors.
