In my thesis I want to describe and prove how the Chinese government uses public procurement as innovation policy to promote the innovation of new energy vehicles in China.
I don’t need you to write introduction and conclusion for me, and I have also almost finished the theory part, so I only need the empirical part.
I wanted to conduct a statistic/regression analysis from the data of:Chinese government NEVS (new energy vehicle) public procurement amount each yearChinese NEVs Patent applications each yearChinese NEVs Patents granted each yearChinese NEVs R & D expenditure each yearChinese NEVs Technology market turnover each year
But unfortunately, I can’t offer you most of the numbers.
I want to prove the hypothesis that public procurement as innovation policy can promote NEVs innovation.
