2. Background Which science or technology fields will be prioritized?
How important is each subfield?
How does a specific subfield influence other subfields?

3. Citation Network

4. Method Calculate the eigenvalues 1 Remove its jth row and jth column
Recalculate the eigenvalues
The relative importance of sector j

5. Correlation between IOF and citations

6. Evolution of influence

7. Relation between subfields

8. Summary
This method provides an innovative approach for answering the two questions raised at the beginning.
Given a set of fields, which is more influential and thus may be supported preferentially?
Given a specific priority, what other fields are necessary foundations for the targeted field and thus may need to be prioritized?
