Final results showed that: the three urban agglomerations in intensity, direction, range and other aspects of economic links there are some differences. On the strength of economic ties, economic ties strength Yangtze River Delta city group and middle reaches of the Yangtze River City Group level city economic ties stronger than the strength of Chengdu-Chongqing Urban Agglomeration of the prefecture-level city, and the maximum total amount of foreign economic ties with the former two urban agglomerations and among the smallest prefecture-level cities vary greatly, and the Chengdu-Chongqing urban Agglomeration these two differences are relatively small; in the direction of economic ties, from the influence of the three urban agglomerations around the city level foreign economic ties are the most prominent role in the influence of different administrative pisions in urban agglomerations three prefecture-level city in the foreign economic links, their economic ties on the middle reaches of the Yangtze River city group prefecture-level city of the most intense, three urban agglomeration economic links have direction center directivity, the economic center of the Yangtze River Delta city group possessed more persity, and the middle reaches of the Yangtze River city group are based in the capital city; in the range of economic ties, the radiation source of the Yangtze River Delta economic ties more net radiation the number of cities and urban agglomerations of more than two other wide range of radiation, net radiation Chengdu-Chongqing urban Agglomeration urban least, the least radiation.
