Vice President Vincent Siew said Friday that President Ma Ying-jeou hopes Taiwanese businesses will change their operational structures from contract to own-brand manufacturing in the post-economic cooperation framework agreement (ECFA) era. To achieve this goal, the government and private enterprises should 'be prepared mentally and should work out implementation measures, ' Siew said at a conference in which he addressed Taiwan's moves to promote the signing of the ECFA with China. He also reminded businessmen to be clearly aware that China is undergoing policy changes amid changes in its domestic market, in which wages are being hiked and calls are mounting for environmental protection measures. Siew explained that economic development undergoes a transformation every 20 years and that China is at present going through its transformation, attaching importance to the development of new energy, new materials, biotechnology and cloud computing. China appears to want to catch up with the developed countries while placing importance on domestic demand. As a result, it is attempting to get rid of its full dependence on exports and is hoping to narrow the economic development gap between its inland and coastal regions and between urban and rural areas. Amid the changes in China, Siew suggested, Taiwanese businesses operating there should adjust their operational structures and perspectives. ECFA, he said, comes 'at the right time' because it will push companies to redefine the China market and initiate new business strategies. The one-day conference on Taiwanese businesses and China's economic development was organized by the Institute for National Policy Research and the Taipei-based Chinese National Federation of Industries.
