Hanxin

Hanxin (simplified Chinese: 汉芯; traditional Chinese: 漢芯; pinyin: Hànxīn) was a notorious case of academic fraud in China. Chen Jin, a professor at Shanghai Jiao Tong University, claimed in 2003 to have developed a new digital signal processing (DSP) microchip called the "Hanxin 1", which would have been the first DSP chip to have been wholly developed in China. However, Chen Jin's invention was later exposed as a Motorola chip with the original identifications sandpapered away.

According to analysts, the case underscores the pressure on Chinese researchers to develop technological innovations which would enable China to bridge the gap with the West. The Hanxin scandal was viewed as a major setback to China's ambition in terms of losses of substantial public funds and time in a race that China had already been losing.
