The Pearl River Delta (PRD) is one of the most important economic zones both in China and in the world. Its rapid economic development has been associated with many environmental problems such as the loss of forests in urban areas. We estimated the accessibility of forests in the PRD by quantifying spatial proximity and travel time. We found that distances from a large proportion of the points of interest (POIs) (~45%) and urban lands (~38%, where ~49 urban residents live) to the nearest forests were greater than 1000 m; suggesting a low spatial proximity to forests. Urban parks—important outdoor recreational areas—appeared to have insufficient forest coverage within their 1000 m buffer zones. When forest accessibility was measured by travel time under optimal modes of transport; it was less than 15 min for most urban lands (~95%), which accommodates 98% of the total urban population. More importantly; the travel time to the nearest forest was negatively correlated with gross domestic product density (GDPd), but not with population density (POPd). The GDPd and POPd; however; increased log-linearly with the Euclidean distance to the nearest forest. In addition to the low proximity to forests; there existed inequalities among urban residents who live in areas with different levels of GDPd and POPd. Future urban planning needs not only to increase the total coverage of urban forests; but also to improve their spatial evenness across the urban landscapes in the PRD.

Some enterprises of the Pearl River Delta had invested in Hunan province, and they played significant roles in Hunan’s economic development. However, the contribution to economic growth in general was not obvious in Hunan. According to the quantitative analysis that Hunan undertook an obstacle to the shift of the Pearl River Delta Industry. It could be found: The actual utilization of foreign investment in Hunan, Hunan road length, the balance of rural and urban residents in Hunan, Hunan consumption level and years of commodity market turnover, these five variables are the key barriers that Hunan could not take over the transfer successfully in Internet era. Five variables representing the Government's institutional arrangements for attracting foreign investment, transport infrastructure, subject to cultural constraints on investment entrepreneurial spirit, the regional market factors in Hunan that be decided from the regional market size and level of development. Therefore, to speed up the transfer of industries in Hunan docking the Pearl River Delta, it must be focused on several aspects of the above and then do the reform and innovation.
