| صنایع کوچک و متوسط (SME) از مهم‌ترین بخش‌های اقتصادی در هر کشور هستند. این صنایع، با ایجاد صرفه‌های تجمع در مراکز صنعتی، معمولاً تبدیل به مراکز رشد می‌شوند؛ در حالی که صنایع بزرگ بر پایه صرفه‌های مقیاس، تبدیل به قطب‌های رشد می‌شوند. در چارچوب اقتصاد منطقه‌ای، صنایع کوچک و متوسط در فضای جغرافیایی و صنایع بزرگ در فضای اقتصادی اثرگذارند. حال آن که صنایع کوچک با تکیه بر آثار انتشار، نقش خود را در توسعه صنعتی و رشد اقتصادی به عنوان یک مرکز رشد ایفا می‌کنند. با پذیرش این امر، مقاله حاضر به بررسی و الگوسازی دو موضوع در زمینه آثار فعالیت صنایع کوچک و متوسط پرداخته است: الگو سازی فرایند انتشار و الگوسازی نحوه انتقال اطلاعات (یا به طور مشابه ابداعات و فناوری). هر دو موضوع، در زمینه نظریه های امواج قابل طرح هستند . میان دو منطقه ی فرضی ، معمولاً اختلاف میان نوع و کارکرد صنایع می تواند تفاوت میان امواج فیمابین را ایجاد کند. با توجه به این که هر صنعت به خودی خود دارای آثار پیشین و آثار پسین است ، هر منطقه نیز متناسب با نوع صنایع استقرار یافته در آن ، می تواند دارای آثار پیشین و آثار پسین بر سایر مناطق در فضای جغرافیایی یا فضای اقتصادی باشد . برای الگوی فرآیند انتشار، از رهیافت الگوهای جاذبه و برای الگوی فرآیند و نحوه انتقال اطلاعات، از نظام انتقال سلسله مراتبی استفاده شده است. در هر دو روش، نتیجه امر به صورت الگوهای انتشار در حالت عام و در شرایط خاص بیان شده است. توابع نظری استخراج شده، بیانگر نحوه تعامل مناطق بر اساس انواع صنایع مستقر در آنها هستند . آثار بیان شده در الگوهای مورد نظر نشان می دهد که صنایع کوچک و متوسط می توانند با ارسال امواج مستمر ابداعاتی ، اطلاعات و سایر امواج توسعه ، تأثیرات مهمی بر مناطق پیرامون داشته باشند. | ||

| Small and medium industries are some of the most important economic sectors in any country. These industries, usually transforming to business incubator by economies of agglomeration in industrial centers, while large industries are becoming growth poles based on economies of scale. In the regional economics framework, SMEs affect the geographic space and large industries affect the economic space. While small industries by relying on the diffusion effects play their role in industrial development and economic growth as a business incubator. The present article is examining and modeling two issues in the field of small and medium industries’ activities effects: the diffusion process modeling and the modeling of how information transmission (or similarly, technology and innovation). Both issues can be brought up in the wave theories. Among two given regions, differences between the type and function of industries can usually make the difference between the waves. considering that each industry has its own preceding and following effects, each region also proportion to the type of established industries in it can have preceding and following effects on the other regions in geographic space and economic space. For the diffusion process model, the approach of gravity model, and for the process pattern and how information transmission, a hierarchical system is used. In both methods, the results are shown in form of the diffusion models in general and under specific conditions. The extracted theoretical functions indicate how the regions interact based on the types of established industries in them. The effects of the considered models show that the SMEs can have significant effects on the surrounding regions around via sending permanent innovation waves, information, and other development waves. | ||
