Invest in technology to improve your country's economic and military power. Technology can be acquired from public market purchases, research alliances, and from spending turns creating technology. The research rate is driven by both the number of research labs and the proportion of research labs to total acres.

All technology categories have a maximum benefit. It is easier to reach the maximum benefit on fewer acres because each point of technology loses some effect as the total number of acres increases. You will need to continually invest in technology if you wish to maintain the same benefits while growing in acres.
