The South wins, industry moves south from the Northern states because there would be no raw goods to support the industry. The agrarian society (large farming culture) of the South would have melded with these new industrial complexes, and cities such as Atlanta, Memphis, Richmond, Charleston, Savannah, Mobile, etc. would have grown exponentially. The CSA would have moved away from slavery within 20 years as industry grew and the economy shifted. Slavery was already an unpopular sentiment in the South at the time of the Civil War. The North would have struggled to support their existing industry without the South's raw goods and would have pushed west much more rapidly. Eventually, the two countries would find common ground and most likely rejoin to form a single country again. It's possible that the North would have invaded again out of desperation.
