Nagrinėjamų prekių pardavimams yra atliekama regresinė analizė, nustatomos prekės gyvavimo ciklo stadijos, apskaičiuojami kainos pokyčio sąlygoti ribiniai pardavimų, paklausos elastingumo kainos atžvilgiu koeficientai. Atlikti tyrimai leidžia įvertinti ir palyginti kainos pokyčio poveikį naujų prekių ir prekių pasekėjų paklausai skirtingose gyvavimo ciklo stadijose.
ENPrice is one of the most important factor to product demand. Right price can bring good profit for enterprise and help to extend product life cycle. The main object of this article is estimate and compare price influence to "new" product and "me-too" products demand in different product stages. In analysis of price influence to product demand we use statistical-mathematics and qualitative - expert methods. In article we analyse product life cycles of six "new" products and three cycles of "me-too" products. Firstly, in purpose to define stages of the product life cycle, we did regression analysis of products sales. By assessment regression curves we define the stages of product life cycle. The price influence to product demand we analyse by demand elasticity and marginal sales. Results of analysis show that the demand of "new" products elasticity to price grow in introductory, growth, early maturity and late maturity stages. The demand elasticity of "new" products is weak in decline stage of product life cycle. Results of analysis approve that the demand of "me-too" products elasticity to price is high during introductory, growth and decline stages. The demand of "me-too" products elasticity is weakest in early maturity stage of product life cycle. In late stage of product life cycle price elasticity to price is high or equal to one.
