Through three years’recovery after new China was founded，the State started planned economy construction in 1953．In May1956，in an effort to intensify leadership towards chemical industry，the Ministry of Heavy Industry’s Chemical Industry Administration．the Ministry of Light Industry’s Pharmaceutical Administration and Rubber industry Administration were merged to form the Ministry of Chemical Industry，paving the way for building and development of New China’s chemical industry．During that period，construction of 10-odd new chemical projects were highlighted such as Jilin，Lanzhou and Taiyuan chemical zones and North China Pharmaceutical Plant among 156 projects whose design and construction were assisted by the former Soviet Union，and socialist transformation was conducted to private chemical firms.
　　In l958，in order to bring central and local initiatives into full play to go in for chemical industry in a big way,the Ministry of Chemical Industry moved a thousand of cadres and engineers and technicians from the ministry organ and institutions and enterprises located in Beijing down to localities．By 1963，chemical bureaus of provinces, municipalities and autonomous regions had been set up in succession, chemical design institutes．research institutes，prospecting and construction units and colleges, and a chemical industrial system was primarily formed. During that period, the chemical industry organized and prepared prototype designs for medium-size and small enterprises involving fertilizer，sulfuric acid，caustic soda，PVC，etc., and provide them for localities for construction in the light of local conditions．Brainstorm tests of synthetic ammonium carbonization process were conducted successfully and many small nitrogen fertilizer plants were set up throughout the country. Three medium-size nitrogen fertilizer plants with self-designed and self-made equipment were constructed，namely，Quzhou Chemical Plant，Wujing Chemical Plant arid Guangzhou Nitrogen Fertilizer Plant．Later，medium-size nitrogen fertilizer plants were set up by stages and in groups, medium-size nitrogen fertilizer plants series with coal，oil and gas as raw materials and trailed a path of developing chemical fertilizer industry through self-reliance. Petrochemicals made debut at Lanzhou Chemical Industry Co. and introduced advanced technologies and equipment of polyvinyl alcohol and vinyl on，sand cracking and LDPE，PP and butanol and octanol from Japan and Western countries.
　　During the ten years’ turmoil，chemical industry suffered severe damage，but still made some progress thanks to workers’ persisting in production．In 1970，the Party Central Committee and the State Council decided to merge the Coal Ministry，
the Oil Ministry and the Ministry of Chemical Industry into the Ministry of Fuels and Chemical Industry. In 1975，the Ministry of Fuels and Chemical Industry was disbanded and the Coal Ministry and the Ministry of Petrochemical Industry were set
up.During that period，the Ministry of Chemical Industry decentralized 359 chemical enterprises and institutions to localities.Small nitrogen fertilizer plants developed so fast that each county had a small nitrogen fertilizer plant．Inland construction was reinforced by moving many chemical enterprises from coast or setting up new enterprises, and chemical industry’s layout was improved．Thirteen 300，000t/a synthetic ammonium，480，000t/a or 520，O00t/a urea and one 300，O00t/a ethylene combined units were introduced．The on-stream of such enterprises greatly upgraded China’s nitrogen fertilizer and petrochemical units and substantially upgraded production technology level of China’s nitrogen fertilizer and petrochemicals.
　　In March 1978,the Ministry of Oil＆Chemical Industry was disbanded and the Ministry of oil Industry and the Ministry of Chemical Industry were resumed．In January 1979．the Pharmaceutical Bureau of the Ministry of Chemical Industry was renamed the China Pharmaceutical Industry Corporation，quit the Ministry of Chemical Industry and joined the State Pharmaceutical Administration．In February l983，the Party Central Committee and the State Council decided to set up the China Petrochemical Corporation(Sinopec)to take charge of 39 enterprises previously under the administration of the Oil Ministry, the Ministry of Chemical Industry and the Textile ministry as well as four 300，000t/a ethylene units and three 300,000t/a synthetic ammonium projects introduced by the Ministry of Chemical Industry．Sinopec then expanded or constructed seven ultra-1arge petrochemical enterprises in Yanshan，Qilu，Daqing，Liaoyang，Yangtse，Jinshan，etc．，constructed and expanded oil refineries in Luoyang，Shijiazhuang，Guangzhou，Gaoqiao and Fuzhou．Production capacity of ethylene--a basic product of petrochemical industry—surpassed 2.4m tons，total output of three main synthetic materials hit6.7m tons on yearly basis．
　　During that period，the chemical circles earnestly implemented the resolutions of the Third Plenary Session of the Eleventh Central Committee of the Chinese Communist Party，carried out gradual，general and significant reform．and deepened opening to the outside world under the guidance of Comrade Deng Xiaoping’s theory of building socialism with Chinese characteristics．After construction of three five-year plans--Sixth Five-year Plan．Seventh Five-year Plan and Eighth Five—Year Plan，the chemical industry has entered a new development era．
　　During that period，chemical circles gave priority to adjustments of investment orientation and general layout and to development of petrochemicals, and energetically developed agrochemicals，basic chemical raw materials and fine chemicals．Chemical product mix was adjusted，proportion of nitrogen，phosphate and potash fertilizers was improved in fertilizers and proportion of concentrated compound—fertilizer was raised．Following stopping operation of hexachloro-cyclohexane soprocide arid DDT—two pesticides---in 1983, a batch of new pesticides were developed and proportion of high efficiency and low residual pesticide was raised. Average annual 1,000 new products were put into operation under rubber sector．The policy of chemical revitalization through science and technology was carried out thoroughly，great achievements were made in tackling key problems in science and technology，technology popularization and research & development，and a complete service system involving development，production，supply，popularization，application with scientific research playing the leading role．Notable achievements were made in opening up，more chemical enterprises earned foreign currencies through export, number of overseas-funded enterprises substantially increased，total capitalization on foreign fund was increased by a large margin，and enterprises were set up ill such open areas as Shanghai Pudong，Hainan，Xiamen，Shenzhen and Beihai to push up development of chemical industry, in line With requirements of socialist market economy, the chemical industry pushed ahead chemical enterprises’ transforming operating mechanism，optimized corporate combination，developed scale economy，and set up large corporate groups with remarkable strength as Jilin Chemical(Group)Corporation，Shanghai Tyre Rubber (Group) Corp．and China Lucky Film Group．State and local chemical market places were set up．China Haohua (Group) Corp．，China United Rubber Corp．and Dongfang Fertilizer Corp．were set up following ministerial structural reform in l 993．Various nationwide social bodies were set up in chemical sectors．Management organization of chemical industry with Chinese characteristics was formed, featuring one slim industrial management core--government institutions，a batch of social bodies and a batch of economic entities.
　　In June 1992, the Party organization of the former Ministry of Chemical Industry made strategic plan for the chemical industry to deepen the reform and to be compatible with socialist market economic system; they decided to form China Haohua Chemical (Group) Corporation on the basis of China National Chemical Construction Corporation(CNCCC), China National Chemical Supply & Sales (Group) Corp., China National Chemical Engineering (Group) Corporation(CNCEC), China National Chemical Equipment Corporation, China National New Chemical Material Corporation which subordinate to the Ministry of Chemical Industry, and Nanjing Chemical Plant to implement the “large corporation, large group” strategy.With the approval of the State Council on December 31,1992, it got business license in February 1993 and became operational in September 1994.　　
　　From 1996 to 1998, by adjustment, reorganization, closedown and merger with others, 18 companies, established when the former Ministry of Chemical Industry was restructured, were put under the administration of Haohua Corporation. It made Haohua more powerful. From 1996 to 1998, China government confirmed that the position of Haohua Corporation had switched from fund "replacing government appropriations with loans " to the provider of state capital in the chemical industy on the state level, which involved 164 chemical enterprises with the total value of RMB 3,129 million. At the beginning of 1998, Haohua Corporation severed its tie with the Ministry of Oil＆ Chemical Industry. After reorganization, it entered into the central management list on the basis of Group system and was under the administration of Enterprises Working Commission of Central Committee 。
　　18 research academies and institutes, subordinate to the former Ministry of Chemical Industry, entered Haohua Corporation in 1999 after they shifted their systems according to Central Policy. The corporation became the largest resident chemical enterprise with the strongest capacity of scientific research in chemical industry, which laid the foundation for achieving the integration of scientific research and production and lifting the core competition of Haohua.　
　　By reconstruction, the Geology & Mine Bureau of the former Ministry of Chemical Industry and its subsidiaries formed China Mingda Mine & Chemical Industry Corporation, and then it was put under the administration of Haohua Corporation In 2001. Such enterprises as Xuanhua Chemical Industry Plant, Hebei Xinji Chemical Industry Corp. entered Haohua Corporation in succession. In the same year, National Planning Commission and the Ministry of Finance issued joint document put the special fund "replacing government appropriations with loans" and operating fund of RMB1,859 million into Haohua and turned them into state capital. And then Haohua Corporation has laid a primary basis of large-scale chemical industry group with the integration of scientific research commercial run, trade and finance business and has owned foreign affairs right, foreign trade right, peculiar chemistry product franchises and non-bank financial business management right.
　　Haohua Corp made developing program during the “Tenth Five-year Plan” period in July 2001, and made clear its orientation of“a large-scale science and technology industry corporation with science and technology oriented, new material as main business, finance and trade as both wings, the integration of science, industry, trade and finance”. And it also ascertained the economic targets during the “Tenth Five-year Plan” period. In 2003, with the incorporation of Hunan Yiyang Rubber Machinery Co., Guilin Rubber Machinery Factory in succession, the rubber machinery production capacity of Haohua leaped into the front ranks of China. In 2004, Haohua Corp purchased Hebei Zhongyi FRP Co., Ltd., got the trusteeship of Siping Lianhua and became the relative shareholder of Henan Yuhang Chemical Company by means of capital increase; Shanxi Yuanping Chemical Group Corp entered Haohua Corp. With capital operation, product mis adjustment and technological innovation, it had got transnormal development and promoted its competition.
　　China National Chemical Corporation was conglomerated by Haohua Corp and BlueStar Corp and started operation in May 2004. A wider development platform was constructed. China National Chemical Information Center(CNCIC), China Mingda Mine & Chemical Industry Corporation、China Chemical Techno-Economics Center, China National New Chemical Material Corporation and China National Chemical Equipment Corporation were transferred from Haohua Corp to China National Chemical Corporation.
　　In 2005, Zigong Honghe Chemical Company was transferred without compensation to Haohua Corp. And in the same year, Haohua became the relative shareholder of Henan Junma Chemical Corp by capital and stock expansion.
　　 In March 2006, Haohua Southern Rubber Company and State-owned Assets Supervision and Administration Commission of Guilin municipal government signed “Transfer Agreement on Property Rights”, and acquired 100% interest of Guilin Tire Factory, Guilin Latex Factory and Rubber Products Factory of Guilin Southern Rubber Company. In June 2006, Haohua Northern Corporation and Tianjin University signed “Letter of Intent for Reorganization of Tianjin Tianda Tianjiu Sci-tech Co., Ltd”. In November 2006, Haohua Corp and Henan Tire Group Corporation Ltd. signed “Transfer Agreement on the State-held Shares of Aeolus Tire Co., Ltd.”, so the equity of 100 million shares of Aeolus Tire Co., Ltd. held by Henan Tire Group Corporation Ltd. was transferred to Haohua Corp without compensation.
