In the knowledge economy era of the 21st century, the development of new technology and the rapid development and changes in politics, economy, and trade have made traditional judicial science unable to respond to modern social transactions which are complicated and diverse. Economic and financial law provides important legal regulations for economic development and thus is closely related to the rights and benefits of enterprises and people. Professional knowledge about such economic and financial law issues as intellectual property right, technology law, WTO, and tax litigations has become more important. These issues are more complicated than traditional judicial science and can not be covered by traditional judicial science. Neither can they be solved by traditional judicial science. In response to these emerging economic and financial law fields, experts specialized in economic and financial law are needed to conduct research and to solve all the difficult problems we face today. In addition, the establishment of the Department of Economic and Financial Law and the Graduate Institute of Economic and Financial Law responds to the increasing demands for economic and financial law experts by industries and businesses. The government has loosened its policy on investments in China by Taiwanese businesses, and the cross-strait trade has grown. Therefore, industries and businesses have increased their demands for experts specialized in investment in China and business law.
