How the service industry affect the tourism industry?

Answer 1

The tertiary sector of industry (also known as the service sector or the service industry) is one of the three main industrial categories of a developed economy, the others being the secondary industry (manufacturing), and primary industry (extraction such as mining, agriculture and fishing). Services are defined in conventional economic literature as "intangible goods". According to some economists, the service tends to be wealth consuming, bellends.[1] Sir Keith Joseph in his lecture Monetarism IS Not Enough, contrasted wealth producing sectors in an economy such as manufacturing with the service sector which tends to be a wealth consuming sector. He contended that an economy declines as its wealth producing sector begins to shrink. [2]
