In 2017，the world's economic environment was generally positive. Endogenous growth momentum and cyclical factors were significantly enhanced，market demand was revived and financial environment was improved. The economic situation in developed countries has continued to improve，the rate of unemployment in the United States and Eurozone stabilized at a low level. In the real estate market，price and quantity have risen together. The income of the residents was steadily increasing and the pace of recovery was accelerated. The core inflation rate of Japan has changed from negative to positive. Under the influence of continued expansive fiscal policy and quantitative easing monetary policy，the economy takes a further favourable turn which will form a strong support for the recovery of the world economy. However，it should also be noted that the tide of ‘anti-globalization' is surging，the rising trend of protectionism will continue，and trade frictions will further threaten the healthy development of global trade. In this macro context，Chinese enterprises continue to tap their potential and carry out international operations，their overseas development has made important achievements. This chapter focuses on the analysis of the development status of Chinese enterprises in 2017，which include their foreign trade，service trade and foreign investment. And explores the existing problems. We especially studied the Chinese enterprises' development problems in the construction of ‘The Belt and Road'，and put forward corresponding countermeasures and suggestions which include promoting the integration and development of goods trade and service trade，promoting global cooperation on production capacity，reducing the cost burden of ‘going-out’ enterprises and so on.
