Global Value Chains includes a series，Among them, value generates value，and at least two links are produced in different countries。Since the epidemic in the new crown pneumonia，Global value chain has received a certain degree of challenge。This phenomenon，Relevant scholars put forward their own views。

Plol Antràs, a professor of economics at Harvard University in the United States，Global value chain includes at least the production or service process from two countries。So，The concept of "Global Value Chain" naturally connects this phenomenon to more and more foreign added value in production。In simple terms，Global value chain can be divided into a "spider web" structure that converges multiple components and components into products in one assembly factory，and the "snake -shaped" structure that creates value in a series of production or service stages。No matter what kind of structure，can all form a more fine international labor division of labor，and bring greater professional income。

Although the global value Bet365 lotto review chain has high efficiency、The characteristics of professionalism and interconnection，but may also be from regional、Some unfavorable factors at the country and even the global level。Holger ) I think，Under the background of the current popularity of new crown pneumonia，The production of all countries is hit at a certain stage，It also affects their ability to supply intermediate products to companies located in other countries。The supply chain interruption that comes with it，Policy makers in many countries start to solve the needs of economic self -sufficiency，They want to formulate a strategy that can better cope with global risks，Even if this strategy may be at the cost of sacrificing the efficiency and productivity of its international division of labor。But，Since the choice of the supplier in the operation is the company rather than the state，The actual effect of this strategy is difficult to evaluate。

Holg further explained，Enterprise management will consciously decide to put it in production by yourself，Still buy from the market。If you purchase from the market，It is a question to purchase from many suppliers from different countries。The cost of establishing a relationship with suppliers is high，Restricting the number of suppliers is the usual practice of bet365 live casino games the enterprise。But，This choice also means，When the company cannot operate normally due to the interruption of one or more suppliers，They may suffer huge losses。So，Management decision makers need to focus on the cost of calculating suppliers，and judge the probability of interruption due to external impact，Extreme events like the epidemic of new crown pneumonia are actually difficult to predict。

Trade protectionism has also brought challenges to the development of the global value chain。From Holg's view，In recent decades，The world economy develops rapidly in the process of globalization。But，Since the epidemic in the new crown pneumonia，Some scholars frequently mentioned the lessons of the 2008 financial crisis，It advocates shortening the global value chain to ensure the safety of its own production。but but，They should also see，One of the lessons is that it is difficult for trade protectionism to survive such a crisis，"Taking the global supply chain is the direction of cautious forward in the future" is a claim that cannot be expressed。Trade protectionism at the cost of sacrificing globalization and international division of labor，It is not beneficial to the development of the global value chain。

　　Digital technology brings a double -edged sword effect

The future development Bet365 app download of the global value chain，Antlas thinks，New technology is one of the decisive factors。For the future of how the new technology will shape the global value chain，It is difficult to give a clear answer at present。He proposed，The slowdown in the development of the global value chain after 2008 will continue in the next decades，Still we are currently on the cusp of the new round of globalization? These problems have to be clarified。

From Antlas,，Global value chain is rapidly changing under the promotion of digital technology innovation。On the one hand，Digital technology helps companies reduce obstacles facing when joining the global value chain，Encourage enterprises to participate in the global value chain。On the other hand，New technology may also affect the relative bargaining ability of different participants in the global value chain。For example，Digital platforms allow the big buyers of developed countries to get more potential suppliers' information，This can cause more intense competition between suppliers，This enhances the ability of these big buyers to negotiate when facing these suppliers。This may bring better trade conditions to leading companies in developed countries，But manufacturers at the cost of underdeveloped countries have a lower Bet365 app download share in the global value chain income。other，Digital platform itself has mastered a lot of information about its platform users，This undoubtedly enhanced their ability to use this information，Some digital platforms are tailor -made and recommended lock buyers，Some digital platforms even use "killing" and other forms to discriminate against consumers。So，The development of the digital platform company also brings new challenges to regulatory agencies seeking fair competition and preventing the abuse of market power。

New technologies have the potential to increase productivity，But they sometimes prove that they are quite destructive，Especially sometimes it will cause the company's demand for workers to decrease。Antlas thinks，Industrial automation and robot technology are a good example。For those companies that seek to reduce labor costs in developed countries，Automation becomes another choice of offshore outsourcing。But，For underdeveloped countries，This fact is worrying，Because they may think that automation threatens their ability to enter the global value chain with cheap labor。Large multinational companies usually design production processes based on the price price of their markets，Then may implement the same production process bet365 live casino games in the host country of the product，This may involve a lot of automation。In other words，Participating in the global value chain may cause industrial automation to spread to underdeveloped countries，This is exacerbated to exacerbate the problem of decreased labor demand caused by automated countries due to automation。other，It is necessary to emphasize，Automation may exacerbate the inequality of the global value chain participation。Similar to investment with physical capital，Automation is usually a supplement to proficient labor，At the same time, replacing non -proficient labor，This increases the uplink pressure of the relative demand for skilled workers，Then the inequality of salary benefits。So，Even if the impact on employment may be weakened due to productivity effect，Automation may also be related to the decline in the proportion of employment population obtained in the global value chain in the global value chain。
