I am tired of reading LN which focus on becoming strong....I want another genre that focus on economics, agriculture that will or may affect the tide of a certain country... example is duke's daughter but only have 9 chapter translated so I want another one. Here it goes at least the MC: Other world, summoned or reincarnated Should be female though I don't mind male A little bit of magic I don't mind Smart not dumb ass will be the person who will be in charge in a certain land and able to change or improve its status.
http://www.novelupdates.com/series/risou-no-himo-seikatsu/ Maybe. If you haven't read it yet. It's not quite what you asked for but it hovers around that territory.
www.novelupdates.com/series/bringing-the-farm-to-live-in-another-world/ i dont read it yet, bit its fit your description
>see economy http://www.novelupdates.com/series/maoyuu-maou-yuusha/ Seriously, I learned more from the LN/manga than from six years at school. No reincarnation, but the rest does fit the bill.
http://www.novelupdates.com/series/death-march-kara-hajimaru-isekai-kyusoukyoku/ The MC quickly becomes OP in the story so then focus most of his effort on being a part time merchant, part time tourist, and full time chef. A little more about nobility than economics but still not all about becoming strong. http://www.novelupdates.com/series/seiun-wo-kakeru/ Modern day blacksmith MC wakes up in a low tech setting. MC helps develop the village both physically (such as population and territory) and economically (trade products and alliances). Edit: Just thought of one more http://www.novelupdates.com/series/hachinan-tte-sore-wa-nai-deshou/ MC is reincarnated as the non-heir son of a poor noble family. MC learns magic and uses it to help financially support his family (such as through hunting or discovering items to be sold to merchants). Eventually becomes noticed by other nobles and becomes rich (as still a preteen) but now has to survive in the world of nobility.

A Desperate Reincarnated Duke Reform 詰みかけ転生領主の改革 Nope... not translated yet... But someday I will turn this into main story... I just like to tease you guys...
http://www.novelupdates.com/series/akuyaku-tensei-dakedo-doushite-kou-natta/ Female Lead, create a better "land" for it's people that were abused by MC's parents http://www.novelupdates.com/series/botsuraku-youtei-nanode-kajishokunin-wo-mezasu/ Male Lead, similar to above and My death flags show no signs of ending, MC makes some actions/decisions that affect "his" people http://www.novelupdates.com/series/tensei-oujo-wa-kyou-mo-hata-o-tatakioru/ Female lead, another otome game reincarnation story where MC tries to avoid their "bad" ending and thereby influences the people around her http://www.novelupdates.com/series/parallel-world-pharmacy/ Male Lead, another reincarnation story, but of a pharmacist that ends up bringing modern day medicine to a medieval placed setting. http://www.novelupdates.com/series/yuusha-yori-saikyouna-kuro-kishi/ Female Lead, gets summoned to another world due to a friend that was summoned as a hero, but arrived before the "hero" did. Not many chapters, doesn't seem like the goal is to become strong, but is in a position to make a difference http://www.novelupdates.com/series/chu-wang-fei/ Smart Female Lead, is reincarnated into a different world due to host dying. So far, doesn't hit the influences the land or world, but the possibility of it is there. Regardless it's a really good novel of a female lead that fends off the schemes of other people who want her dead/gone
