چکیده

دستیابی به محیط­زیست پاکیزه به همراه رشد اقتصادی و رفاه جامعه از آرزوهای هر جامعه مدرن محسوب می­شود. محققان حوزه کارآفرینی در سال­های اخیر، افزایش همبستگی میان کسب‌وکار و محیط‌زیست را پذیرفته‌اند؛ زیرا فعالیت‌های کارآفرینانه، یک پیشران کلیدی برای پایداری اقتصادی، اجتماعی و محیط‌زیستی به حساب ­می­آید. بررسی مطالعات حوزه کارآفرینی نشان می‌دهد که ادبیات تحقیق این حوزه در سال­های اخیر به‌سرعت توسعه یافته است و پیشرفت آن در طیف وسیعی از موضوعات صورت گرفته است. بااین‌وجود، یکی از دغدغه‌های علمی نویسندگان مقاله حاضر پرداختن به موضوع پیوند کارآفرینی و محیط­زیست است. در واقع شناخت فرصت‌های تحقیقاتی مرتبط با این حوزه، کمک شایسته­ای به توسعه نظری و تحقیقات کاربردی علوم کارآفرینی و محیط­زیست می­نماید. در این میان، مفهوم پیچیده گرایش کارآفرینانه سبز از جذابیت بالایی برای پژوهش برخوردار است. در این پژوهش به بررسی ادبیات و تحقیقات مرتبط با پیوند حوزه­های کارآفرینی و محیط‌زیستی با رویکرد فراترکیب پرداخته شده است. بر این اساس در مقاله حاضر پس از بررسی موضوعی و محتوایی 141 منبع، 25 عامل در قالب هشت مفهوم و دو مقوله شناسایی شدند که وزن عوامل با روش آنتروپی شانون تعدیل‌شده تعیین شده است. در این راستا مهم­ترین عوامل مؤثر بر گرایش کارآفرینانه سبز کسب­وکارها به ترتیب عبارت‌اند از: «نوع صنعت»، «حمایت مالی»، «پاداش و مشوق‌های دولت برای اقدامات کارآفرینانه سبز»، «شبکه‌های اجتماعی»، «کارآفرینی سبز جهت سود اقتصادی»، «هنجارهای اجتماعی در مورد محیط‌زیست» و «تعهد، توجه و شناخت مدیران یا مالکان نسبت به محیط‌زیست».

چکیده [English]

Achieving a clean environment along with economic growth and welfare is one of the aspirations of any modern society. Nowadays, researchers have accepted the correlation between the scopes of business and environment because entrepreneurship activities have been acknowledged as a significant driving force for economic, social, and environmental sustainability. A review shows that the entrepreneurship literature has experienced rapid growth, with many developments reported on a broad spectrum of topics. Nevertheless, one of the main concerns of the authors of present contribution is the nexus of entrepreneurship and the environment. Indeed, recognition of research opportunities in relation to the green entrepreneurial orientation concept can largely contribute to the theoretical development and empirical studies in entrepreneurship and environmental science. So in the meantime, the mysterious concept of green entrepreneurial orientation has become a very attractive research topic. In this research, the literature related to the nexus between the fields of entrepreneurship and the environment with a Meta synthesis approach has been studied. Accordingly, in the present article, after a thematic and content review of 141 sources, 25 factors were identified in the form of eight concepts and two categories, the weights were determined by the modified Shannon entropy method. In this regard, the most important factors affecting the entrepreneurial orientation of green businesses are: "Type of industry", "Financial support, rewards and incentives for green entrepreneurial actions", "Social networks", "Green entrepreneurship for economic benefits", "Social norms about the environment" and "Commitment, attention and knowledge of managers or owners to the environment.
