ABSTRAK
Indonesia dan Jepang sepakat membentuk kerjasama Indonesia-Japan Economic Partnership Agreement (IJEPA) pada tanggal 13 Juli 2008 dengan mengikutsertakan sektor otomotif. Hal ini mengundang pertanyaan karena Indonesia tidak memiliki keunggulan komparatif seperti infrastruktur memadai, tenaga kerja terampil, dan teknologi yang dapat bersaing dengan negara lain. Melalui penelaahan terhadap konsep FTA, trickle down, dan spillover effect, didukung wawancara dengan beberapa institusi, ditemukan bahwa Indonesia menginginkan investasi dan penurunan tarif, peningkatan bargaining power, perluasan akses pasar, serta transfer teknologi. Kelima hal tersebut menjadi alasan yang mendasari disepakatinya sektor otomotif dalam kerjasama IJEPA. Sektor otomotif Indoesia juga memiliki nilai strategis dan berpotensi sebagai pasar otomotif terbesar di kawasan Asia Tenggara sehingga Jepang pun berniat menjalin kerjasama otomotif dengan Indonesia.
