![]() If the value was positive, a space-time divergence would be observed. The value is negative because the time value is reduced (fewer hours traveled). Combining the endogenous growth model with a. Consequently, STC was for that period of -0.072 hours per year or -4.32 minutes per year. This paper studies the effect of highspeed rail (HSR) on urban economic growth using a panel data set comprising 285 Chinese cities in 20072017. By 2000, this travel time was reduced to 2.6 hours. In 1950, it took 6.2 hours to travel between A and B. The above figure provides an example of space-time convergence between two locations, A and B. Variation in travel time ( ΔTT) is divided by the time period ( ΔT) over which the process took place the slope of the curve. To measure space-time convergence ( STC), travel time information is required for at least two locations and two time periods. It is closely related to the concept of speed, which indicates how much space can be traded for a specific amount of time. Space-time convergence investigates the changing relationship between space and time, including the impacts of transportation improvements on such a relationship. The perceived shrinkage of time and space has been described as time-space convergence by Janelle in 1968 and as time-space compression by Harvey in 1990. This implies that two locations can be reached in a lesser amount of time, which is usually the outcome of innovations in transport and telecommunications. Space-time convergence (also labeled as space/time compression) refers to the decline in travel time between similar locations. ![]()
