چکیده
صنایع سبز و انرژیهای تجدیدپذیر، به دلیل مسائل مختلفی من جمله بحث گرمایش جهانی و لزوم پاسخگویی به نیاز روزافزون جوامع به انرژی به خصوص در سالهای اخیر مورد توجه قرار گرفته‌است و پژوهشگران معتقدند گذار به اقتصاد و صنایع سبزتر اساساً حول محور نقش تغییرات و تکامل فناورانه می‌چرخد. این تکامل فناورانه معمولا توسط فعالیت‌های حل مساله که دانش‌های مختلف از حوزه‌های یکسان یا مختلف فناوری را ادغام کرده و از ویژگی تجمعی دانش بهره می‌برد، انجام می شود. با توجه به ضرورت و اهمیت توسعه فناوریهای های تجدیدپذیر، هدف پژوهش حاضر اینست که به بررسی تنوع دانشی ریشه های فناورانه در توسعه این فناوری ها و تاثیر این تنوع بر همپایی فناورانه کشورهای فعال در این حوزه بپردازد. از آنجا که انرژی خورشیدی بزرگترین منبع تولید انرژی های تجدیدپذیر در جهان است، فناوری های این حوزه به عنوان مورد مطالعه انتخاب گردید. این پژوهش از نوع کاربردی فن‌سنجی بوده و با استفاده از روش تحلیل استنادی پتنت انجام شد. به منظور اجرای پژوهش، در گام اول پتنت‌های حوزه انرژی خورشیدی در بازه زمانی 1980 تا ۲۰۱۶ از پایگاه پتنت درونت احصا شد. در گام بعد، استنادات رو به عقب هر پتنت استخراج شد. درگام سوم تعداد کلاس‌های فناورانه مختلف مرتبط با این حوزه شناسایی و با استفاده از شاخص، اصالت هر پتنت با استفاده از زبان R محاسبه و در سطح ملی تجمیع شد. در گام چهارم روند شاخص اصالت برای کشورهای موفق به همپایی بدست آمد. در نهایت مدلسازی رگرسیون نشان داد که هم برای کشور چین و هم برای کشور کره جنوبی، اصالت دانش و تنوع ریشههای فناورانه با همپایی فناورانه رابطه مثبت داشته است. در انتها نتیجه گیری و پیشنهادت پژوهش ارائه گردید.

چکیده [English]
Green industries and renewable energy have been considered because of various issues such as global warming and the need to meet the growing energy needs of communities, especially in recent years, and researchers believe that the transition to greener economies and industries is primarily centered on the role of technological change and evolution. This technological evolution is usually accomplished by problem-solving activities that integrate different sciences from the same or different fields of technology and take advantage of the cumulative nature of knowledge. Given the necessity and importance of the development of renewable technologies, the purpose of this study is to investigate the diversity of knowledge of technological roots in the development of these technologies and the impact of this diversity on the technological catch-up of countries active in this field. Since solar energy is the largest source of renewable energy production in the world, technologies in this field were selected as the study. This research is an applied type of Technometrics and was performed using the patent citation analysis method. In order to conduct the research, in the first step, patents in the field of solar energy in the period 1980 to 2016 were obtained from the Derwent patent database. In the next step, the backward citations of each patent were extracted. In the third step, the number of different technology classes related to this field was identified, and using the index, the originality of each patent was calculated using the R language and aggregated at the national level. In the fourth step, the trend of originality index for successful countries was achieved. Finally, regression modeling showed that for both China and South Korea, the originality of knowledge and the diversity of technological roots were positively correlated with technological catch-up. In the end, the conclusion and research suggestions were presented.
