Question 1

How many words does a PhD thesis usually need?

Accepted Answer

Humanities PhD theses typically require 80,000-150,000 characters; STEM PhD theses typically require 50,000-100,000 characters. Requirements vary significantly by discipline.

Question 2

How to distill innovation points in a PhD thesis?

Accepted Answer

Innovation points are not generated spontaneously but emerge from extensive literature review and methodological training. Consider three dimensions: theoretical (new concepts/modified theories), methodological (new or improved methods), applied (new problems or evidence for policy/practice).

Question 3

Can I publish papers first and then write my PhD thesis?

Accepted Answer

Absolutely, and this approach is recommended. CSSCI/SSCI/SCI papers published during PhD studies are often the basis for core dissertation chapters. Maintain a "big picture" perspective when writing papers to ensure they form a cohesive research system.

Question 4

What are typical similarity rate requirements for PhD theses?

Accepted Answer

Requirements vary by university, typically below 10%-20%. However, similarity issues for PhD theses are more about citation standards — direct quotes must be cited, and paraphrasing also requires attribution.

Question 5

What if I fail my PhD defense?

Accepted Answer

Failed defenses happen and are not the end. Defense committees provide specific revision feedback. After revising, you can reapply for defense (typically after 3-6 months). Use this time to fully prepare, especially addressing weak areas exposed during the defense.
