Abstract:With the national strategic goal of accelerating the construction of a modern public cultural service system, increasing the financial investment in the cultural industry and public cultural sectors has become the material means and policies and measures to implement the national strategy. However,the observation of the cultural sectors at the grass-roots level shows that the fiscal investment through the traditional cultural industry is a supply-side guarantee. This elevates the production capacity of the public products of the cultural sectors, but also has significant negative impacts, which are primarily the closure and “soft contraction” of the industry caused by consolidated industry interest, and the “institutional idling” and supply-side inefficiency caused by the internal circulation of resources in the system. To establish a modern system of public cultural services, we need to adjust our scheme and policy. By virtue of the platform function of digital information technology, we need to realize the overall transformation of macro policy-making, promote the policy benchmark to shift from the supply-side public input logic of “state-cultural units” to the consumption-side incentive logic of “state-individuals”, and guide the performance improvement on the supply side with policy innovation on the cultural consumption side, thus rebuilding the legitimacy of the public cultural policy, and guiding the transformation of the current national cultural undertaking system to the national public cultural service system through macro policy innovation.
