It reflects the general direction of bilateral relations, yet has its own development trajectory. As Sino-US relations had their ups and downs in the 1990 s, space cooperation between the two countries was relatively consistent and stable. But as economy and trade became more and more deeply intertwined in the 21 st century, space cooperation lost its momentum. This paper intends to explore the reasons behind this strange development trajectory by analyzing the security, political, legislative and economic factors affecting bilateral space cooperation. It also tries to analyze the prospect of Sino-US space cooperation in President Trump's term.展开更多

It mainly includes setting up service platform and providing scientific and technological services; organizing economic and trade negotiation and exchange, and promoting farmer-supermarket partnership; providing financial services and solving fund-raising problems. In line with these fields, we analyzed existing problems: (i) regional development is unbalanced and organization lacks internal connection; (ii) the development in some counties (cities) is to be improved, and the promotion effect is not significant; (iii) there is shortage of talent and the innovation strength is not enough; and (iv) it lacks system and management lacks restriction mechanism. Finally, we put forward countermeasures and recommendations: strengthen propaganda and cultivate farmers' cooperative awareness; incorporate rural cooperative economic organized united association into formal system arrangement, and absorb professional talents; innovate upon organization system of rural cooperative economic organized united association and improve service methods; improve internal operating mechanism and innovate upon working contents of rural cooperative economic organized united association at new development background.展开更多
