What policies did Mussolini’s regime introduce in the 1930s?

His political policies aimed to help him consolidate his power. Mussolini, as a prime minister of a coalition government, did not have full control as there were only 35 fascists. He had to exercise moderation and seek cooperation to entrench power.

Before the dictatorship era, Mussolini tried to transform the country's economy along fascist ideology, at least on paper. In fact, he was not an economic radical, nor did he seek a free-hand in the economy. The Fascist Party held a minority faction of only three positions in the cabinet, excluding Mussolini; and providing other political parties more independence. During the coalition period, Mussolini appointed a classical liberal economist, Alberto De Stefani, originally a stalwart leader in the Center Party as Italy’s Minister of Finance, who advanced economic liberalism, along with minor privatization. Before his dismissal in 1925, Stefani "simplified the tax code, cut taxes, curbed spending, liberalized trade restrictions and abolished rent controls", where the Italian economy grew more than 20 percent, and unemployment fell 77 percent, under his influence.
