Enterprise innovation is the basic requirement for building an innovative country. Since the launch of the Three Gorges Project in1993, the project has been faced with a lot of world-class difficulties. Based on reality, the Three Gorges builders realized great breakthroughs in the dam fast-concreting technology, the hydro design, installation and manufacturing of the700kW turbine, the stability of the high-side-slope of the double-way five stage ship lock, the water system on extra high water head, the manufacturing and installation of the grand scale door and some other key technologies through the means of technology integration and innovation, introducing new technologies into China, fully absorbing them and innovating or innovating in some original technologies. As a result, the Three Gorges Project has accomplished great achievements. According to the" Diamond System" model by Michael E. Porter in analyzing the national competitive strength, the Three Gorges Project has its own characteristics in production factors, requirement conditions, and the performances of related and supporting industries, and also in the strategy and structure of the enterprise, competitors of the enterprise and some other aspects. To rely on the support of the government and the society and seize the precious opportunity for hydropower development, the builders take the Three Gorge Project construction as a big stage for technology innovation and winning honor for the country. Nevertheless, talking about most enterprises in China at present, some protruding problems like low rate of technology introduction and absorption, the lack of intellectual property right and the lack of research input still exist, which severely hamper innovation. To realize the goal of building an innovative country in2020, domestic enterprises should foster and improve the innovation ability in six aspects, namely, relying on the resources of the country and the society, bringing their innovative ability into full play,  carrying out the scientific development concept, tapping their self-independent innovation ability, strengthening the construction of the innovation team, and increasing in research input and exerting a coordinated effect and collective scale advantage of innovation.
