The first part of the article analyzes the three indicators of international market share，trade competitiveness index，revealed comparative advantage，and finds that the product structure of the industrial competitiveness of lower middle income countries has changed totally from 2000 to 2016，and as for the trend of change，there is no uniform law in the pluralization；The second part selects the top five lower-middle-income countries（India，Indonesia，Pakistan，the Philippines，and Vietnam）with the largest volume of trade with China，and uses three indicators to compare the industrial competitiveness of the six countries. From the analysis of international market share indicators，the gap between China’s manufacturing product competitiveness in typical middle-lower income countries is still quite large，and there is no possibility of surpassing it in a short period of time；it can be compared from the perspective of trade competitiveness index indicators. The competitive advantage of China’s products is still relatively obvious，and the competitive strength is relatively stronger，but there is no big difference between the two in terms of international market share；from the perspective of revealed comparative advantages，China can be found lightly disadvantaged in comparison with typical lower income countries，there does not exist such as the international market share and trade competitiveness index reflect the same obvious competitive advantage. Sections 3 and 4 describe from the perspective of the status quo of the trade relations between the typical lower middle income countries and China and the United States，and set forth China’s future further coordination with lower middle income countries in national economics and trade relations.
