I only have time for the first paragraph, perhaps others can look at the rest of it for you...

The first paragraph is too long and awkwardly constructed. I suggest breaking it into more sentences, something like:

"Since the 1990s a revolutionary transformation has been occurring in our society. We are moving from the era of industrial economy to the era of knowledge economy. In this process enterprises experience great contextual change, especially in the environment of competition. In the 21st century, this competition will become increasingly fierce."

You have also misspelled "outsourcing."
