Traditionally, economic development has been about attracting new businesses.
Often, this is accomplished by offering incentives, usually prorated based on the number of jobs created, but such efforts are zero-sum in the sense that businesses attracted by one community are lost from another community. Moreover, businesses attracted by incentives often lack loyalty and are lost once incentives run out.
Economic development experts are coming to realize that growing local businesses, rather than attracting businesses from the outside, is a more effective means of promoting economic growth. Rather than getting into a bidding war for, say, a new manufacturing plant, the idea is to provide strategic benefits to local businesses thereby promoting job creation.
Knowledge is power in this sense, but testing your knowledge in the real world and learning from others who have done it are much more valuable. You need the mind-set to learn it, and follow through with blind enthusiasm.
