Korean Tourism Industry and the Chinese YouKe [1]

While Korean domestic industries such as tourism, logistics and service sectors have been reaping numerous benefits from Chinese tourists have brought about, no one knows for sure how long this trend will last.

According to a recent survey on of Chinese tourists who [2] paid a visit to  had visited 16 different countries, when asked about if they are willing to pay another visit to the visited country those countries again, of those who recently travelled to Korea, only a small portion of people said that they would come to Korea again. Korea ranked quite low as 14th out of the 16 countries, which [3] well demonstrates their stay in Korea was not so satisfying.

The practice of overcharging tourists was regarded as a chronic problem. Furthermore, most notably, while more and more Chinese tourists are turning their eyes on a budget tour, Korea is not equipped with enough reasonably priced accommodations to serve them. Foreign tourists often complain that there are few accommodation options: either luxury-priced hotels or rundown motels.

Notes:

[1]  I don't know what a "YouKe" is.
[2] "paid a visit" is informal and casual.  As a phrase, it is typically used for visits to friends.  The tone of the paragraph is more formal/informational, so "had visited" fits the paragraph better. 

[3] "well demonstrates" sounds odd, but isn't wrong.

You tend to write long sentences, longer than most native-speaker writing.  This can make the sentences difficult to read and increases the opportunity for grammatical errors.
