Abstract

The role of intra-industry trade has been emphasized in international commerce since the 1960s. Innovation and government size, which affect goods and services production and government presence in international commerce, have also been highlighted since then. This study examines the influence of these two factors on international trade and estimates their effects in linear and logistic transformation models from the years 2000 to 2016 using HS four-digit codes. This research focuses on 20 main import and export industries of Iran and selected commercial partners. The authors estimate the model using the bidirectional panel data method and analyze the data using Stata 15 software. Results indicate that in both models there is a U-shaped relationship (non-linear) between innovation and intra-industry trade. However, government size increases intra-industry trade in these models. Linder variables decrease intra-industry trade but GDP per capita increases intra-industry trade. Other control variables (geographical distance and membership in economic organizations) show the expected impact on intra-industry trade.

Abstract [فارسی]

از دهه 60 تاکنون، نقش تجارت درون صنعت از کل تجارت بین­الملل بسیار مورد تاکید قرار گرفته است و با توجه به نقش نوآوری در عرصه تولید کالاها و خدمات و حضور دولت­ها در سطح فعالیت­های بین­الملل، در این پژوهش سعی گردیده است تاثیرات این دو متغیر کلیدی در طول سال­های 2016-2000 بر تجارت درون صنعت، با استفاده از کدهای چهار رقمی  HS، در مدل های خطی و لجستیکی مورد بررسی قرار بگیرد. این تحقیق بر 20 صنعت اصلی واردات و صادرات ایران و شرکای تجاری منتخب متمرکز است. مدل با استفاده از روش پنل دوطرفه و با استفاده از نرم­افزار Stata 15  برآورد و تجزیه و تحلیل شده است. نتایج نشان می­دهند که در هر دو مدل بین نوآوری و تجارت درون صنعت، رابطه U شکل (غیرخطی) وجود دارد. از طرفی، اندازه دولت نیز تجارت درون صنعت را در این مدل­ها افزایش می­دهد. همچنین متغیر لیندر تجارت درون صنعت را کاهش می­دهد؛ اما متغیر تولید ناخالص داخلی سرانه آن را افزایش می­دهد و سایر متغیرهای کنترل (فاصله جغرافیایی و عضویت در سازمان­های اقتصادی) نیز دارای تاثیرات مورد انتظاری بر تجارت درون صنعتی هستند.
