The Beijing-Hangzhou Canal flows from north to south through Beijing, Tianjin, Hebei, Shandong, Jiangsu and Zhejiang provinces, and runs through five major water systems in China-Haihe River, Yellow River, Huaihe River, Yangtze River, Qiantang River and a series of lakes. From the North China Plain to the Yangtze River Delta, the terrain is flat, rivers and lakes crisscross, and fertile fields are thousands of miles away. Since ancient times, it has been the main producing area of grain, cotton, oil, sericulture and hemp in China.

Dense population, high degree of agricultural intensification and great production potential. Since modern times, the railway and highway networks of Beijing-Tianjin, Jinpu, Shanghai-Nanjing and Shanghai-Hangzhou have been built one after another, which are closely connected with the canal. Along the line, industries have sprung up and towns are dense, which is the place where the economic essence of China gathers.

The Beijing-Hangzhou Grand Canal is one of the richest agricultural areas in China with developed industries. There are large and medium-sized coal mines in Yanzhou, Jining, Tengzhou, Fengxian, Peixian, Xuzhou, Pizhou and Huaibei, connecting industrial cities such as Shanghai, Nanjing, Xuzhou, Zhenjiang, Changzhou, Wuxi, Suzhou, Yangzhou and Hangzhou.

In order to make the "golden waterway" produce "golden" benefits, Shandong, Jiangsu and Zhejiang provinces have renovated, expanded and channelized various sections of the Grand Canal, which has rejuvenated the Millennium Grand Canal and made it the second "golden waterway" in China after the Yangtze River.

The main ports along the canal are Jining, Xuzhou, Pizhou, Siyang, Huaiyin, Huai 'an, Baoying, Gaoyou, Yangzhou, Zhenjiang, Changzhou, Wuxi, Suzhou, Wujiang and Hangzhou.
