Internet Penetration                                                                          

According to Ministry of Science and ICT, Internet user population and smartphone user population in Korea in 2017 reached 90.3 percent and 93.0 percent respectively. In addition, Korea ranked 16th globally with over 45 million internet users. 

Current Market Trends                                                              

The growth of the Korean retail sector is led by e-commerce.  While e-commerce is growing rapidly, traditional retailing channels are suffering.  Consumers tend to go to traditional stores for window shopping but purchase goods at online retail sites to find the best deals.
One of the biggest trends in online retailing is convergence with other platforms.  Internet portal sites, social network services, TV home shopping, etc. now all have online shopping functions and the popularity of their platforms are increasing since consumers want a one-stop shopping experience that includes product reviews and price, purchasing, and paying with new online payment solutions associated with the platforms. 

Domestic e-Commerce (B2C)                                                      

Domestic e-commerce sales have been increasing for the past few years reaching $100.8 billion in 2018.  Online purchases surpassed hypermarkets’ sales in 2016 making e-commerce the biggest retail channel in Korea.  Popular e-commerce sites include Auction, G-market, 11st, Coupang, Ticket Monster (TMON), and We Make Price.  Based on the number of mobile and PC users combined, 11st was ranked the first in 2017 with 19 million visitors.  11st was also the first for mobile users followed by Coupang.

Business to Business (B2B) e-Commerce                                                                   

Korean B2B e-commerce market data is not available; however, due to the explosive expansion of business to consumer (B2C) e-commerce and tough competition among e-commerce players, e-commerce companies have been looking to expand into B2B e-commerce on consumable sales to small and medium size companies.  G-market was the first one to launch a B2B shopping site called ‘Biz on’ in 2012. Auction also has B2B sites called ‘Biz club’ for food ingredients and ‘Biz plus’ for other consumables.  Interpark has ‘I market Korea’ that integrates B2B and B2C services.  We Make Price started ‘We Make Price Bizmall’ in 2016. With 5.4 million business owners and 3.5 million small and medium-sized companies, the B2B e-commerce market is expected to be very competitive.

e-Commerce Services                                                       

In 2018, the most popular item sold through Korean e-commerce platforms was travel and transportation services, which makes up 13.8 percent of the total sales.

Business to Government (B2G) e-Commerce                                                             

For B2G E-commerce, Korea ON-line E-procurement System (KONEPS) is the only channel in Korea.  In 2015, 48,000 public organizations and 320,000 companies were registered on this system with a total volume of business at $42 billion.  The site deals with more than 60 percent of Korea’s public procurement market, which is about $105 billion and is recognized for its high standards by the UN and OECD.

Mobile e-Commerce
