I propose a shadow price approach to measuring the stringency of land use regulation. A regulation is considered more restrictive if the land developer is willing to pay a larger amount for a marginal relaxation of the regulation. I show that existing theory-based measures of land use stringency are either equivalents or variations of this shadow price measure. Using data from China, I demonstrate that it is possible to compare the stringency of two kinds of land use regulation, a key advantage of this shadow price approach.
