This paper sounds an alarm about disparate efficiencies among China's regions in the allocation of innovation inputs. A theoretical measure of misallocation is adopted to gauge the distortions that exacerbate the inefficiency of resource allocations across In addition, this paper probes the factors that co-move with China's innovation resource misallocations. We find that, although an advanced financial market is beneficial to innovation efficiency in China, both the government's extensive development of transportation infrastructure and the preferential treatment given to state-owned enterprises (SOEs) and foreign-invested enterprises (FIEs) negatively correlate with innovation efficiency. We conclude that emerging economies that are experiencing R&D input expansion, such as China, should be cautious in ensuring efficient resource allocations.

This paper presents a method for blast furnace lining thickness measurement with a 3D laser scanner and image registration method. A laser scanner is used to measure the inner profile through an opening on the upper part of the furnace. Two data point sets are obtained before and after the lining repairing process respectively, and data registration algorithm is employed to acquire rigid body transformation so as to compare the difference between both point clouds based on the same coordinate system. The difference represents thickness added to the initial lining. Furthermore, by comparing mechanical dimensions with the measured profile, residual lining thickness can be obtained.
