极左年代诞生的中国现代大型乙烯工业孵化器,奠定了未来几十年中国乙烯技术国产化的基石。1973年3月22日,国务院总理周恩来批准了《关于增加设备进口、扩大经济交流的请示报告》。这也就意味着之前国家计委呈报国务院的三个技术进口报告正式通过。这个预计共耗资43亿美元的引进方案就是著名的“四三方案”。四三方案后因追加计划,总引进花费资金超过50亿美元,这是中国继1950年代引进苏联援助的“156项工程”之后,第二次大规模的技术引进。燕山石化30万吨乙烯项目是“四三方案”三个乙烯项目之一,更是当时中国规模最大,也是国内唯一一个
The very large-scale ethylene industrial incubator in China, which was born in the very left of the left, laid the cornerstone of localization of ethylene technology in China in the coming decades. On March 22, 1973, Premier Zhou Enlai of the State Council approved the “Request for a Report on Increasing the Import of Equipment and Expanding Economic Exchanges.” This means that the State Planning Commission before the State Planning Commission formally passed the report of the three technologies imported by the State Planning Commission. This is expected to cost a total of 4.3 billion US dollars of the introduction of the program is the famous “four or three programs.” Due to additional plans after the April 3 Proposal, the total cost of introducing more than 5 billion U.S. dollars was the second large-scale introduction of technology after China introduced “156 projects” of Soviet aid in the 1950s. Yanshan Petrochemical 300,000 tons of ethylene project is the “four three program” one of the three ethylene projects, but also China’s largest, but also the only one
