- Abstract:
- This article analyzes the process of China’s industrial development and industrial structure changes in recent years. With the further development of China’s urbanization, the current tertiary industry’s contribution to the national economy has occupied the first place, and its water consumption has also accounted for about 60% of the total urban water consumption. Through a comparative analysis between China and developed countries such as the United States, Britain, and Japan, it shows the differences in water consumption per 10 000 yuan of GDP, water consumption per 10 000 yuan of value-added GDP in the secondary and tertiary industries, and water efficiency. It is found that there could be further progress for water saving in China’s tertiary industry. If we failed on water saving, the water consumption of the tertiary industry will increase to 2.7 times of the current valve by 2035, which will be 1.6 times of the current urban total water consumption. Therefore, water saving in the tertiary industry has become the main direction of water saving in Chinese cities. Through the analysis of the unbalanced and inadequate development of water saving in the tertiary industry in China, the water-saving concept and water-saving model driven by culture, management, and technology are proposed. Besides, this article has also conducted a deep investigation on the water saving of the air-conditioning cooling circulating water system, which is the major water users in the tertiary industry. Related water saving measures are suggested. This paper contributes to the development on the water-saving and support is as a priority governance policy, which could improve the urban carrying capacity limited by water resources rigid constraints, and also provide new ideas for further promoting the in?depth and refined development of urban water saving in China in the new era.
