We promoted rapid growth in investment. We guided and stimulated non-government investment by means of well-leveraged government investment. We implemented a plan to invest an additional 4 trillion yuan over two years. In 2009, the central government's public investment was 924.3 billion yuan, 503.8 billion yuan more than in the previous year's budget. Of this, 44% was invested in low-income housing, projects to improve the wellbeing of rural residents, and social programs; 16% in independent innovation, restructuring, energy conservation, emissions reductions, and ecological improvement; 23% in major infrastructure projects; and 14% in post-Wenchuan earthquake recovery and reconstruction. Fixed asset investment increased 30.1% nationwide. We further improved the investment structure. Rapid investment growth effectively compensated for the shortfall created by shrinking external demand, strengthened weak links, and laid a solid foundation for long-term economic and social development.
We accelerated the post-Wenchuan earthquake recovery and reconstruction work. We have already invested 654.5 billion yuan, 65.5% of the total planned investment, in the worst hit areas. Thanks to the government's strong support, the selfless assistance of people throughout the country, and the hard work of residents of the earthquake area, the badly damaged areas have taken on a brand-new appearance, with new towns rising straight out of the ground, and villages brimming with vitality. All this fully reflects the boundless love of the Chinese nation and powerfully demonstrates the incomparable superiority of the socialist system.
2. Vigorously carrying out economic restructuring, and shoring up the foundation for long-term development. We closely integrated sustaining economic growth with economic restructuring, and moved more quickly to resolve structural problems limiting economic development.
We further strengthened the work related to agriculture, rural areas, and farmers. The central government used 725.3 billion yuan to support agriculture, rural areas, and farmers, an increase of 21.8%. We raised the minimum grain purchase prices by a large margin. We began implementation of the plan to increase grain production capacity by 50 million tons nationwide. We continued to improve living and working conditions in rural areas. We implemented rural drinking water safety projects that benefited 60.69 million people, increased the number of methane gas users by 5.1 million, built and upgraded 380,000 kilometers of roads and 266,000 kilometers of electric power lines and renovated 800,000 dilapidated houses in the countryside, and helped build permanent housing for 92,000 nomadic families. We also intensified our efforts to fight poverty. As a result, working and living conditions notably improved in poverty-stricken areas.
We intensified industrial restructuring. We formulated and implemented a plan for restructuring and invigorating ten key industries. We encouraged enterprises to accelerate technological upgrading, and provided 20 billion yuan to support 4,441 technological upgrading projects. Further progress was made in mergers and reorganization in key industries. We made great efforts to restrict excess production capacity and redundant development in some industries. We closed down 26.17 million kilowatts of small thermal power stations, and eliminated backward facilities with total production capacity of 16.91 million tons in the steelmaking industry, 21.13 million tons in the iron-smelting industry, 74.16 million tons in the cement industry, and 18.09 million tons in the coke industry. We accelerated the implementation of major national science and technology projects, and spent 151.2 billion yuan of central government funds on science and technology, an increase of 30%. We vigorously supported the widespread use of domestically innovated products, and the development of emerging industries such as clean energy and third-generation mobile communications. We vigorously strengthened infrastructure development; put 5,557 kilometers of newly built railway lines into operation; opened 4,719 kilometers of new expressways to traffic, accelerated urban rail development; and built, renovated or expanded 35 civil airports. We increased the installed power-generating capacity by 89.7 million kilowatts, began supplying gas through the western section of the second line of the project for shipping natural gas from west to east, accelerated construction on the South-to-North Water Diversion Project, and began reinforcing 6,183 dangerous reservoirs.
