Research on the path to improve the level of straw resource utilization: taking Shandong Province as an example

How to promote the rapid development of the use of straw resources in China has become one of the important ways to achieve high-quality development in society. This paper adopts econometric methods and takes Shandong Province as the research object to build a set of “financial expenditure—intermediate path—straw resource utilization level” promotion path methodology system, aiming to consider the impact intensity of financial expenditure (as an important means for the government to stimulate the development of straw resource industry) on straw resource utilization level through different paths. The results show that the impact of the two intermediate paths of the development level of waste resources and the development level of infrastructure development are the most obvious. For every 1% increase in fiscal expenditure, the utilization level of straw resources will increase by 2.693% and 2.437%, respectively. The financial expenditure has a positive impact on the level of straw resource utilization through education level, agricultural development foundation, energy conservation and environmental protection investment, and innovative R&D investment, that is to say, the financial expenditure through the above paths is of positive significance for improving the level of straw resource utilization. Among them, the path with the lowest impact intensity is innovation R&D investment, and it is suggested that innovation R&D investment should be inclined to straw utilization technology. The above conclusions can provide scientific theoretical guidance for the further improvement in the utilization level of straw resources in Shandong Province, and also provide reference for the government departments when formulating industrial adjustment plans.
