Abstract: This study employed a Cobb-Douglas stochastic production frontier function to estimate the level of technical efficiency. The results of the analysis showed that cropping season of mango growers have been round year. The result of study contributed to tropical fruits efficiency of three seasons instead of only focusing on efficiency of one season or total a year. The findings revealed that season 3 ranked first in terms of technical efficiency (58.2%), followed by season 1 (53.6%) and then season 2 (49.2%). Moreover, the input variables that explained technical efficiency were fertilizer (root), fertilizer (leaf) and labor in season 1; pesticide, fertilizer (leaf) and labor in season 2; and pesticide, fertilizer (root), fertilizer (leaf) and labor in in season 3. In addition, major determinants of socioeconomic characteristics influenced positively on technical efficiency were plant density and land area in season 1 and season 3; market access, plant density and land area in season 2.

Abstract: Aging population has become a world-wide challenge for not only social services, but also the built environment of neighborhood. Community facility is a key element of built environment that has significant impact on elderly's daily lives. However, current planning and design guidelines mainly proposes the requirement of provision of community facilities and is lack of knowledge about older people’s needs, preferences, and use patterns of community facilities. Most relevant studies from western countries cannot be directly applied in the context of Asian cities due to their different urban densities, degrees of car dependence, and culture. This study aims to explore elderly’s needs and characteristics of use pattern of community facilities in local neighborhoods. In addition, this study also intends to identify the key influential factors of elderly’s use of community facilities. Six focus group meetings were conducted in Elderly Community Centers in Kwun Tong from Oct 2019 to Ja
