This study investigates how the strengthening of intellectual property rights, which are expected to have both positive and negative impact on exports, affects the production fragmentation of patent-intensive industry. We first measure total export, value-added export and value-added-export ratio (VAX ratio) from WIOD(world input output database) during 1995~2011. In addition, using the IPR index and industry-level patent intensities, we empirically test the effect of strengthening of IPRs on international production fragmentation for 23 industries in 40 countries. The results first answer the question if strengthening of intellectual property rights have a positive impact on value added exports and total exports of the patent-intensive industry. According to the results, as the intellectual property rights are strengthened, the value added exports and total exports in the patent intensive industry are relatively increased compared to the patent intensive industries. That is, the effect of strengthening the patent protection system is biased toward the patent-intensive industry, and it has a comparative advantage in the industry. Secondly, we empirically test if the strengthening of intellectual property rights strengthened the production fragmentation in the patent-intensive industry. The results show that the production fragmentation in patent - intensive industry was relatively reduced compared to that in patent - intensive industry. Therefore, as the patent protection system is strengthened, the domestic technological innovation of the patent - intensive industry is promoted and it is estimated that the production fragmentation is relatively weakened by promoting the production of the technical material used as the intermediate inputs. These results provides policy implication that in order to cultivate a patent-intensive industry domestically, the strengthening of intellectual property rights has a positive effect. However, these results may be due to the industry-specific characters in patent - intensive industry and to see the impact of strengthening of IPRs on other industries, further detailed investigation should be followed.

본 연구는 수출 및 경제성장과 관련하여 상반된 기대효과를 갖고 있는 지적재산권 강화가 특허집약적 산업의 상품생산분할 패턴에 어떤 영향을 미치는지 연구한다. 국가간 생산분할 측정을 위해 1995년-2011년간의 WIOD(world input output database) 데이터를 이용하여 총수출, 부가가치수출, 부가가치수출비율(VAX ratio) 등을 계산한다. 이와 함께 지적재산권 보호정도를 측정하는 IPR지수와 산업별 특허집약도를 이용하여 각국의 지적재산권 강화가 상품 생산분할에 어떻게 영향을 미쳤는지를 검토한다. 40개국 23개 산업의 데이터를 이용하여 분석한 결과, 지적재산권 강화로 인해 특허집약적 산업의 부가가치 수출과 총수출이 상대적으로 증가하였음이 나타났다. 또한 지적재산권 강화는 특허집약적 산업에서 VAX ratio로 측정된 상품생산분할을 감소시키는 것으로 나타났다.
