According to the NatureIndex records in 2013, 2014 and 2015,
Vietnam is surprisingly experiencing consecutive drops on high-quality research paper output. Vietnam's output drops from 8.23 in 2013, to 8.03 in 2014 and 6.96 in 2015. That's indeed a surprising result! Because
Vietnam is the ONLY Asian developing country that is experiencing a two-year consecutive drop! This looks really weird, because:
- Vietnam people are definitely very smart people, and they are proud of their education system
- Vietnam is making remarkable economic growth in recent years, so there should be more investment to R&D
- The base record of Vietnam is extremely small (0.1% of China), so it should not be very difficult to make some growth
Are there any particular reasons to the consecutive drops of Vietnam? Or is it maybe NatureINDEX staff are very stupid, so they makes wrong calculations on Vietnam's result?
Any ideas are welcome.

What is NatureIndex?
The Nature Index is a database of author affiliation information collated from research articles published in an independently selected group of 68 high-quality science journals. The database is compiled by Nature Research. The Nature Index provides a close to real-time proxy for high-quality research output at the institutional, national and regional level.

What is WFC?
Weighted fractional count (WFC) accounts for the relative contribution of each author to an article, and adjusts for the abundance of astronomy and astrophysics papers.
