Abstract(s)
A habitação é o principal ativo da maioria das famílias, pelo que a volatilidade dos preços
pode afetar a decisão de compra dos potenciais proprietários.
O presente estudo pretende deste modo auxiliar na tomada de decisão ao nível individual e
ao nível dos decisores políticos nos aspetos relacionados com a habitação em Portugal. Ao
nível individual, pretende servir de meio de auxílio na decisão de compra/investimento, quer
do comprador, como do investidor. Ao nível dos decisores políticos, quer sejam de âmbito
municipal, intermunicipal ou nacional, como ajuda na tomada de decisão sobre as melhores
políticas de promoção, renovação e reabilitação da habitação nas suas áreas de intervenção.
Para este trabalho foram utilizados dados disponíveis no PORDATA – Base de Dados Portugal
Contemporâneo, de todos os 308 municípios de Portugal. A metodologia adotada
consiste na utilização de uma regressão linear múltipla, no sentido de perceber quais os
fatores que mais influenciam o valor médio das habitações transacionadas por município.
Posteriormente efetuou-se uma análise no sentido de identificar possíveis cluster s dentro
dos municípios, tendo em conta estes fatores.
Os factores considerados incluem variáveis relativas à Localização dos municípios, Densidade
Populacional dos municípios, Poder de Compra dos habitantes dos municípios, Dimensão
média das Famílias dos municípios, Desemprego nos municípios, Qualidade Ambiental
nos municípios, Envelhecimento nos municípios, Nível médio de Educação nos municípios,
Estado Civil dos habitantes dos municípios, Habitação Própria pelo proprietário nos municípios,
Habitações existentes nos municípios. Os resultados sugerem que apenas a densidade
populacional e a qualidade ambiental não têm influência significativa no valor médio por
município das habitações transacionadas. Podem ainda considerar-se 2, 3 ou 4 clusters de
municípios, destacando-se sempre um grupo de municípios com o VMPT muito mais alto
do que os outros.
Housing is the main asset of most families, therefore, price volatility can affect potencial owners’purchasing decision. The present study aims to support decision-making at individual level and at the level of political decision-makers at the level of housing in Portugal. At the individual level, it intends aid in the purchase/investment decision, either of the buyer, as well as the investor. At the level of political decision makers, whether they are municipal, inter-municipal or national, it intends to be an aid in decision-making on the best policies for the promotion, renewal and rehabilitation of housing in their intervention areas. In this work data available in PORDATA – Portugal Contemporary Database of all 308 municipalities in Portugal were used. The methodology adopted consists in a multiple linear regression, in order to understand which factors most influence the average value of the dwellings traded by municipality. Subsequently, an analysis was carried out in order to identify possible clusters within the municipalities. Factors considered include variables related to Location of municipalities, Population Density of the municipalities, Purchasing power of the inhabitants of the municipalities, Average size of families in the municipalities, Unemployment in municipalities, Environmental Quality in municipalities, Aging in municipalities, Average level of education in municipalities, Civil status of the inhabitants of the municipalities, Own housing by the owner in the municipalities, Existing housing in municipalities. The results suggest that only population density and environmental quality have no significant influence on the average value per municipality of transacted housing. 2, 3 or 4 clusters of municipalities can be considered, always highlighting a group of municipalities with a much higher housing price than the others.
