【正文】 rce logistics development, the need to promote coordinated development of crossborder emerce with crossborder logistics and crossborder logistics work coordination。 Crossborder logistics。 Traditional trade into the modern elements of electronic merce, from the traditional offline way of contact, trading, payment, etc, are turning to the Inter channel on the attentive。 (2) the traditional crossborder emerce business enterprise development. Traditional enterprise along with the emergence and development of electricity, involved in the electricity business, and gradually involved in crossborder emerce market. The enterprise mainly traditional retail enterprises, such as wallmart, Carrefour, etc 。( 4) Logistics panies involved in crossborder emerce business. Some logistics enterprises with the aid of its own logistics resources and advantages, crossborder emerce business. I mainly include overseas online shopping, Canova Brazil, etc. The crossborder electronic merce development present situation The United States and Japan in 2020 Inter users of crossborder emerce usage were investigated, the result shows that the UK39。 On the import side acceptance package more than million, about billion RMB. In the general administration of customs for the record of the crossborder emerce service pilot enterprises, which has more than 2020, the British have published more than 10 supporting policies, some related to crossborder business process and system gradually improve. Crossborder payments to obtain rapid development, PayPal as one of the world39。(2) developed the traditional retail crossborder logistics enterprises, such as America39。s Cadis count, etc.。(4) electric business enterprise selfbuilt logistics system。6 new crossborder logistics enterprises, etc. The crossborder logistics development present situation Crossborder logistics has its generality, but also with international characteristics, range larger, more farreaching, crossborder logistics is not only closely connected with social and economic activities in a number of countries, more influenced by multiple countries in many aspects, the influence of many factors. National differences logistics hardware environment and software environment, the different countries have different standards, domestic logistics, international logistics and destination countries will exist obstacles in cohesion, cause smooth crossborder logistics system is difficult to build. Logistics environment difference, lead to in the process of crossborder logistics, transportation and distribution, need to face different kinds of law, culture, customs, ideas, language, technology, facilities, etc., increasing the difficulty of crossborder logistics operation and system plexity. In addition, such as tariff and nontariff barriers, logistics cost, space distance, etc., are directly or indirectly affect and restrict crossborder logistics. Lack of highend logistics services and valueadded services, to provide logistics system integration, supply chain optimization solutions, cloud puting, big data logistics information platform, crossborder logistics finance, overseas instant ability insufficient, in addition, domestic logistics, international logistics and destination countries in such aspects as cohesion, visualization, information transparency performance is poorer, impact and reduce the customer satisfaction of crossborder logistics. 2. Coordination with crossborder logistics lack of crossborder emerce Synergy is a word has a long history, the main emphasis on coordination between the various elements in the system, synchronous, cooperation and plementary. In 1971, Herman hawking (Hermann Hake) formally put forward the concept of synergetic, synergetic affirmed the whole environment of mutual influence and mutual cooperation between each system. Collaborative logistics work refers to all the elements of logistics work system, each link in such aspects as resources, objectives, operational coordination, synchronization, cooperation and plementary to each other, logistics work system, coordination and cooperation between the service object and the external environment, in order to realize the overall process of value increment and capability of logistics work. Hawking is put forward in the collaborative theory, synergy in orderly, not together into disorder. Coordination with crossborder logistics lack of crossborder emerce Crossborder emerce to stimulate and promote the crossborder logistics, and mature, with the development of crossborder emerce will be more and more high to the requirement of crossborder logistics, from basic modities space displacement function implementation, to the time shorter, cheaper more and better services, a variety of valueadded services, etc. Crossborder logistics reverse driving and restricts the development of crossborder emerce. Crossborder logistics satisfaction ascension will improve the satisfaction of crossborder emerce, crossborder logistics level is higher, the more likely they were to promote the further development of crossborder emerce, on the other hand, a long time, high cost, low service level and the lack of logistics valueadded services, etc., will hinder the development of crossborder emerce, even seriously restrict crossborder emerce growth. Therefore, crossborder emerce and crossborder logist
