The analysis has been done for three different countries, USA, Germany and Japan. The result indicates the percentage report in Good/Substantial progress rate or No/little progress rate in 2016.
In my opinion, the spread of knowledge in Industry 4.0 can be seen to be quite wide across. In 2016, it was not just in Europe or US but also in Asia, the subject has surfaced even though the progress rate was not that high as compare to Germany and USA. As of now, even China, India and South Korea shown quite a progressive mentality towards Industry 4.0 but things are rising with time to catch the tide.
