Investigating relationships between road freight transport, facility location, logistics management and urban form

This paper examines road freight transport activity and its relationship with facility location, logistics management and urban form through an analysis of 14 selected urban areas in the UK. Improved understanding of this relationship will assist planners when making transport and land use decisions. The findings suggest that several geographical, spatial and land use factors have important influences on freight activity in urban areas. Commercial and industrial land use patterns affect the types and quantities of goods produced, consumed, and hence the total quantity of freight transport handled. This also influences the distances over which goods are moved and by what specific mode. There has been relatively low growth in warehousing in many of the selected areas over the last decade compared to the national average as well suburbanisation of warehousing in some locations. This affects the origin and destination of journeys visiting these facilities and typically increases the distance of such journeys. A greater proportion of road freight has been shown to be lifted on internal journeys in large urban areas than in smaller ones. Journeys within urban areas have been shown to be less efficient than journeys to and from the urban area in the 14 locations studied due to the much smaller average vehicle carrying capacities and lower lading factors for journeys within urban areas. The length of haul on journeys to and from urban areas studied was found to be greatest for those areas with a major seaport and/or which were geographically remote. This affects the road freight transport intensity of goods transport journeys.

Reforms, incentives, welfare and productivity growth in Chinese wheat production

Following the 1978 rural reform, a series of agricultural reforms were introduced in China with an aim to create incentives for the farmers to produce more. However, the nineties’ reforms towards liberalization eventually resulted in a huge drop in agricultural production, which apparently motivated the grain self-sufficiency program in 1998. For a dataset that covers wheat production during these reforms, we examine how and to what extent these reforms affected the Total Factor Productivity (TFP) and the welfare of wheat farmers in China, both at the national and at the regional level. We find that although the nineties' price reforms led to a relatively faster growth of the incentivized TFP of wheat production, they failed to improve profits vis a vis welfare for the farmers. A series of weather shocks in the early nineties resulted in a scarcity of cultivable land and a shortage of agricultural labour, which eventually led to a sharp increase in their relative prices. The introduction of grain self-sufficiency program stabilized these agricultural prices but destroyed the growth in TFP for most regions. However, this reform resulted in some improvement in farmers’ welfare. Wheat farmers in China therefore experienced a trade off between productivity and welfare; competition boosted their productivity and regulation improved their welfare. Not only these findings add a completely new set of results to the existing literature, they can also form a strong basis for future agricultural reforms in China.
