Answer:
Technology developments have made significant impacts on both humans and the environment in which they live. However, there is limited whole-of-system understanding of ancient technology development. This paper aims to uncover the evolutionary pattern of the ancient Chinese agricultural technology system that focused on land and water mobilisations from 8000 BC to 1911 AD. Our findings show that agricultural technology in China transitioned through an extremely slow, S-shaped pathway, increasing only ten fold in over 8000 years. The technology system was initially driven by tangible tools (40% of growth), then by technological theories and practices that contributed more than 50% of growth. Its development was spatially inclined to the Yellow River then to the Yangtze River region, where over 45% of technologies were developed. This study provides an empirical baseline for comparative studies between pre-industrial and industrial technologies. Greater understanding of the mechanisms of technology development will be required to reorientate technology development for present and future generations.

3. Governments usually buy road building and military equipment; building infrastructure and purchases of military materiel for an army are government jobs, not the job of private companies.
