Internally, the manufacturers should increase the technical inputs, strengthen the products' quality, and increase the products' functions.

Externally, in terms of content issues, collecting enough copyrighted content is a key issue facing everyone in China's e-book production chain.

President of People's Literature Publishing House, Pan Kaixiong, believes that publishing companies should explore new business models.

"The digital publishing sector in China now faces some challenges such as lack of effective research and related knowledge, shortages of funds, and the publishers have not established a successful business model to profit."

In spite of that, digital manufactures still believe that the e-book has huge market potential, as long as strengthens its product performance, expands the market with multi-media promotions, and fights against piracy through copyright laws.

Wang Bangjiang, vice-president of Hanwang Technology, one of the major e-book manufacturers, says he believes the industry is profitable.

"With our own advanced technology and service, we should plant the legal copy concept firmly on the reader's mind, and make it known that full performance can only be achieved through copyrighted products And I believe it is still a promising industry with high profit."

Given the advantages like portability, multimedia format and rich content, e-reading is not just gaining popularity, but also quietly challenging traditional book reading.
