Abstract: From the perspective of resource allocation redundancy, this paper constructs the mechanism model of the influence of the production and innovation dual resource allocation efficiency on the overcapacity of emerging industries; then it discusses such influence on the linkage overcapacity of emerging industries by bringing demand factors into the model. Taking the photovoltaic industry as an example and making use of the market demand-supply ratio, it measures the capacity utilization rate of the industry as a whole and its three links, and quantitatively measures the resource allocation efficiency and technological innovation efficiency and their impact on the capacity utilization rate. The findings show that the improvement of the capacity utilization rate of the photovoltaic industry depends on the improvement of the production and innovation dual resource allocation efficiency; the resource allocation efficiency mainly has a positive impact on the capacity utilization rate of the upstream and downstream enterprises, but due to the increase of supply, it has negative impact on the capacity utilization rate of the middle-stream enterprises; the technological innovation efficiency has an obvious positive effect on the capacity utilization rate of the downstream enterprises, however, due to the structural adjustment, it failes to have positive effects on the improvement of capacity utilization of the upstream and middle-stream enterprises in the short term.
