Coccia, Mario Scientific data for measuring the evolution of technological innovation: using US historical data of some Funtional Measures of Technology in the farm tractor, locomotive, generation of electricity in steam-powered and internal combustion plants Mendeley Data Scientific data for measuring evolution of technological innovation: using US historical data of some Funtional Measures of Technology (FMT) in the farm tractor (1920-1968), locomotive (1904-1967), generation of electricity in steam-powered and internal combustion plants (1920-1970) FMTs for farm tractor in the scientific data enclosed are: - fuel-consumption efficiency in horsepower-hours over 1920-1968 CE indicates the technological advances of engines (a subsystem) of farm tractors. This FMT represents the dependent variable P in the model. - mechanical efficiency (ratio of drawbar horsepower to belt or power take-off –PTO- horsepower) over 1920-1968 CE is a proxy of the technological advances of farm tractor. This FMT represents the explanatory variable H in the model. For freight locomotive, FMTs are: - Tractive efforts in pound over 1904-1932 CE indicate the technological advances of locomotive. This FMT represents the dependent variable P in the model. - Total railroad mileage over 1904-1932 CE indicates the evolution of the infrastructure system of railroad. This FMT represents the explanatory variable in the model. For steam-powered electricity-generating technology, FMTs are: - Average fuel-consumption efficiency in kilowatt-hours per pound of coal over 1920-1970 CE indicates the technological advances of boiler, turbines and electrical generator (subsystems of steam-powered plant). This FMT represents the dependent variable P in the model. - Average scale of plant utilization (the ratio of net production of steam-powered electrical energy in millions of kilowatt-hours to number of steam powered plants) over 1920-1970 CE indicates a proxy of the technological advances of the overall electricity-generating plants. This FMT represents the explanatory variable in the model. For internal-combustion type electric power technology, FMTs are: - Average fuel-consumption efficiency in kilowatt-hours per cubic foot of gas 1920-1970 CE indicates the technological advances of boiler, turbines and electrical generator (subsystems of internal combustion plant). This FMT represents the dependent variable P in the model. - Average scale of plant utilization (the ratio of net production of electrical energy by internal-combustion type plants in millions of kilowatt-hours to total number of these plants) over 1920-1970 CE indicates a proxy of the technological advances of the overall electricity-generating plants with this internal-combustion technology. This FMT represents the explanatory variable in the model. For model see the steps to reproduce.
