云计算是智能时代竞争制胜的关键“国家基础设施”。当前全球云计算市场集中度高，呈现“3A”格局；中国云计算市场则呈现“一超多强”格局。近年来全球云计算市场总体平稳增长，北美地区云计算市场占据主导地位，中国等新兴云计算国家云计算市场发展势头迅猛；国内公有云市场规模保持较高速度增长，私有云市场规模增速放缓但总量相当可观，大部分增长为本土云计算厂商贡献。本文对中外云计算代表性企业（阿里云与亚马逊AWS）、主要发达国家促进云计算产业发展的做法进行了比较分析。在此基础上，从环境与安全、技术与应用、产业与生态、国际交流与合作等方面提出了促进我国云计算产业发展的对策建议。
Cloud computing is the key of “national infrastructure” for the victory in the smart era. The current global cloud computing market is highly concentrated and appears a “3A” pattern；China’s market of cloud computing is a “Only super Power and Multi-great Power” pattern. In recent years，the global cloud computing market has steadily grown overall，and the market in North America has dominated. The cloud computing market in China and other emerging cloud computing countries has a rapid development momentum；the domestic public cloud market maintains a relatively high growth rate and the private cloud market grows rapidly. Private cloud market growth slowed but the total amount was considerable，and most of the growth was contributed to local cloud computing vendors. This article compares and analyzes the China’s and foreign cloud computing representative enterprises（Ali cloud and AWS）and analyzes the major developed countries’ efforts to promote the development of the cloud computing industry. Based on the above，we propose strategies and suggestions for promoting the development of China’s cloud computing industry from the aspects of environment and security，technology and applications，industry and ecology，and international exchanges and cooperation.
