FDI and Outsourcing provide two ef ective channels for China ' s manufacturing industry to embed into the global value chains，but there are dif erences in the technology spillover. This paper utilizes input-out-puttablesandFDIdata，selectspaneldataof 19manufacturingindustries，basedonC-Dproductionfunc-tion，and verifies these dif erences. Evidence shows that the technology spillover we get through outsourcing is much higher than that through FDI，and the technology spillover in a capital-intensive industry is more remark-able than that in a labor-intensive industry no matter what kind of channel is taken.
