Abstract: Based on the Symbiosis Theory, this paper constructs an“Industrial Symbiosis Level Evaluation Index System”from the four dimensions of integration, competition, complementation and dependence, then it analyzes the symbiosis of the manufacturing industries between China and the countries along“the Belt and Road”route. On such basis, this paper extends the Stochastic Frontier Gravity Model to study the trade efficiency of the manufacturing industries in China and in the countries along the“Belt and Road”route in the market field and the product domain respectively under the symbiosis environment during the period of 2008-2016. The results show that the bilateral manufacturing industries have a better level of symbiosis; the integration and dependence have a significant positive impact on the bilateral trade, while the competitiveness and complementation have a significant negative impact. On the level of market field, the overall trade efficiency between China and the countries along the route is lower and relatively stable, while the efficiency of Southeast Asian countries is relatively higher, and it is relatively lower in Central and Eastern European countries. On the level of product domain, the trade efficiency is relatively lower in the primary product sector in China and the countries along the route, while it is relatively higher in the industrial manufactured product sector.
