At present，the production capacity cooperation along “the Belt and Road” has made good progress in various aspects such as rapid increase of the production capacity，diversified ways of cooperation，gradual improvement in carrying out various relevant policies，increase of “export-oriented” enterprises with advantages in both traditional and emerging industries，a boom of private enterprises while state-owned enterprises keeping the dominant production capacity. However，the production capacity cooperation along “the Belt and Road” still remains at the preliminary stage with many difficulties and problems to be solved. For example，the system and mechanism to promote production capacity collaboration is unsound and the construction of the supporting service system is lagging；there exist great differences in corresponding systems and technological standards under foreign circumstances，for which the Chinese enterprises are not fully prepared yet；Chinese “export-oriented” enterprises have not joined their forces，causing horizontal self-competition among them in some areas；there is a lack of ability in enterprises for internationalization，especially a lack of internationalized talent teams；the sovereign credit of the countries along the proposed route is poor，with the existence of extraterritorial long-term risks.Henceforth，These difficulties and problems need to be solved step by step，and there is a great space for production capacity collaboration between China and most of the other countries along the proposed route in the future，according to an estimate based on Industrial Complementary Index. Therefore，this paper suggests corresponding measures from such aspects as the establishment of a sound system and mechanism for boosting production capacity collaboration and a sound supporting service system，the implementation of localization tactics，the innovation of business operation models，the cultivation and scout of internationalized talents as well as a focused study on the countries along “the Belt and Road”.
