چکیده مقاله :
مقدمه و هدف: شناخت رابطه متقابل بین بخشهای مختلف اقتصادی یک کشوراز جمله بخشهاي كشاورزي و صنعت مي تواند برای ارزیابی سیاستهای اقتصادی گذشته و همچنين سياستگذاريهاي موثرتر در آينده بسیار مفید واقع شود
مواد و روشها: شاخص بهره وري مالم كوئيست براي اندازه گيري رشد بهرهوری بخشهاي کشاورزی و صنعت و همچنين از الگوهاي مناسب اقتصاد سنجي در قالب پانل ديتا طی سالهای 1400-۱۳۸۶ برای ۳2 استان كشور بهره گرفته شده است.
يافته ها : نتایج نشان داد كه رشد بهرهوري در بخش كشاورزي تاثير مثبت و معني داري روي ارزشافزوده اين بخش داشته ولي رشد بهره وري بخش صنعت روي ارزش افزوده بخش كشاورزي تاثير معنيداري ندارد. همچنين رشد بهره وري هم در خود بخش صنعت و هم در بخش كشاورزي تاثير مثبت و معنيداري روي ارزش فزوده بخش صنعت دارد. بطوريكه يك درصد افزايش رشد بهرهوري در بخش كشاورزي 2/0 درصد ارزش افزوده بخش صنعت را افزايش ميدهد
بحث و نتیجه گیری: از لحاظ تحريك بهرهوري يك ارتباط يك طرفه از بخش كشاورزي به بخش صنعت وجود دارد. به عبارت ديگر رشد بهره وري بخش كشاورزي روي بخش صنعت تاثير گذار هست ولي رشد بهره وري در بخش صنعت، بخش كشاورزي را تحت تاثير قرار نميدهد. البته با توجه به تفاوت ساختار صنعت و كشاورزي در استانهاي مختلف شدت و حدت اين ارتباط نيز متفاوت است. بنابراين با انجام سرمايهگذاريها و ايجاد ساختار مناسب ميتوان ارتباط متقابل اقتصادی بین بخشهای کشاورزی و صنعت در مناطق مختلف را تقويت كرده و موجبات رشد بيشتر هر دو بخش را فراهم آورد.
چکیده انگلیسی :
Introduction: Recognizing the nterrelationship between different economic sectors, including agriculture and industry, can be very useful for evaluating past policies and also for more effective policymaking in the future.
Materials and Methods: In the present study, the Malmquist productivity index and appropriate econometric models in the form of panel data were used for 32 provinces of the country during the years 1400-1386.
Findings; The results showed that productivity growth in the agricultural sector had a positive and significant effect on the added value of this sector, but productivity growth in the industrial sector did not have a significant effect on the added value of the agricultural sector. On the other hand, productivity growth both in the industrial sector and in the agricultural sector has a positive and significant effect on the increased value of the industrial sector. So that a one percent increase in productivity growth in the agricultural sector increases the added value of the industrial sector by 0.2 percent.
Conclusion: In terms of stimulating productivity, there is a one-way relationship from the agricultural sector to the industrial sector, while productivity growth in the industrial sector does not affect the agricultural sector. Of course, Due to the structural differences between industry and agriculture in the provinces of the country, the intensity of this relationship also varies. Therefore, by making appropriate infrastructure investments, the economic relationship between the agricultural and industrial sectors in different regions can be strengthened and further growth of both sectors can be provided.
