Labor intensity is the relative proportion of labor (compared to capital) used in a process. Its inverse is capital intensity. (Wikipedia)

Capital intensity is the amount of fixed or real capital present in relation to other factors of production, especially labor. At the level of either a production process or the aggregate economy, it may be estimated by the capital to labor ratio, such as from the points along a capital/labor isoquant. (Wikipedia)
