Development of the cultivated mushroom market from the standpoint of time series sustainability

The article deals with the issues of sustainable development of the world market of cultivated mushrooms. The authors of the article have studied the time series of the world gross value, world volumes of imports and exports, the world price index for cultivated mushrooms and truffles in order to analyze their growth and dynamics. The results of calculations carried out using the statistical database of the Food and Agriculture Organization of the United Nations from 1961 to 2022 showed that the indicated time series are non-stationary. The gross value of mushroom production increased 70 times during the study period, the volume of imports increased 98 times, the volume of exports increased 93 times, and the producer price index doubled. The price index for cultivated mushrooms and truffles is stable without sharp fluctuations. The authors reveled shifts in a series of world gross value of mushroom production in 2000, 2009, 2011. Additive emissions, level shifts and temporary changes were found in the dynamics of world imports and exports.
