On public finances, Clinton wanted to raise taxes while Trump is eyeing fiscal spending cuts. Trump will likely announce more infrastructure investment, which will keep the US fiscal balance in the red, and cut diplomatic and overseas military costs.
On trade, Trump is expected to be tough against China, raising dumping and subsidy allegations against the country. He may also increase tariffs on imports from China. However, some economists saying that Trump won't challenge the status quo of China-US relations. Trump is against NAFTA and TPP, two global level trade deals.
Concerning the financial markets, Trump wants to loosen regulations on Wall Street, the opposite of the Democrats' stance. But the financial industry still sees Trump as a major uncertainty for the US economy and reacted negatively to Trump's victory. Trump has said that he hates low interest rates. He says low rates are the source of over-investment and asset price bubbles.
Still, Trump might not do anything about it as analysts say low rates would tame the overall debt level in the US markets and keep infrastructure investments cheap.
