Economic base analysis 区位商数（重定向自Location quotient）
Economic base analysis was developed by Robert Murray Haig in his work on the Regional Plan of New York in 1928. Briefly, it posits that activities in an area divide into two categories: basic and nonbasic. Basic industries are those exporting from the region and bringing wealth from outside, while nonbasic (or service) industries support basic industries. Because of data problems, it is not practical to study industry output and trade flows to and from a region. As an alternative, the concepts of basic and nonbasic are operationalized using employment data. |
