Technology innovation pushes economic growth, even if researches fail

I always believe that technology is a key factor that drive long term economic growth. The content of China's 13th Five Plan shows that Chinese spending on R&D will continue to expand. Chinese spending on R&D was 200 billion dollars last year, second only to the US. Considering the size of the Chinese economy, this figure is very reasonable. There are many fascinating ideas about technology innovations discussed in the five year plan, from aircraft engines to "quantum teleportation". I do not think the success of these plans are the key, I think that the spending on the research and all the side products during the research are more important. Huge spending on research will increase more job places and income of many firms which are relative to the projects. Moreover, during the research process, many new technologies may be innovated and used in our consumer goods. Even some researches might fail in the end, the jobs it creates and unexpected technology improvement already add value to the economy.
