I think once a year or every other year, a city, county, state, or country ought to do this, and show it's taxpayers what they are getting for their dollars. After all, it's tax incentives, and it's the infrastructure we all pay for (water, sewer, roads) that allow for those businesses to be in your area.
Plus, it's a prime opportunity for those companies to showcase their wares, works, accomplishments, achievements, and to let people know what they need in terms of job requirements, openings, etc,
