With a population of 6 million plus, Dalian is a huge city. China is     part of the trend of populations moving toward urban areas, which     will require the cities here to continue to morph into new entities     as time goes on. It also means that there are very few stand-alone     homes, and most people live in pseudo-condominium buildings. A great     thought experiment to demonstrate the population of China was     pointed out by James Fallows recently which says that, since China     and the United States are about the same size in terms of land, to     get 1.3 billion people into the boarders of the U.S. you would have     to add the populations of Canada and Mexico, in addition to all     of South America's population... and since that still wouldn't be     enough, add in the populations of Nigeria and Japan. That is roughly     what China is dealing with in terms of population. 
     So what does this mean for urban planning, construction plans and     current-but-constantly-changing living conditions? The building J's     parents live in was probably built about 15 years ago, but there is     already talk of tearing it down and rebuilding. That is partially     because of the constant urban re-planning going on for the reasons     given above. It is also because the construction methods and     materials have advanced considerably in the past decade. For     example, around ten years ago they bought a hot water heater that is     completely solar. It is a round container made of metal mounted on     the roof of the building. Environmentalists (like myself) are     excited by the fact that the water is heated entirely by solar     energy, but there are days--particularly in winter--where there is     not enough hot water to take a shower. For comparison, when we went     to J's uncle's place, which he bought in 2007, he showed us his     solar-electric hybrid hot water system. That said, in winter,     depending on what you've done that day or have planned for the next     day, taking a shower every single day may not really be     necessary--and I am fine with that. People will plan their living     conditions according to what they are comfortable with. 
     However, in China, they seem to take this a step further. To     illustrate, in the States, the value of a condominium will be     relative to the interior design and conditions, so that two units in     the same building are not necessarily the same value. In China,     there is no appraisal of individual units based on their condition     or features; apparently the value is based on area. That means that     if and when this building--or any other--is torn down for "urban     re-planning", the government will reimburse the residents only the     area-based value. The residents that invested in, say, a hybrid hot     water heater are not given any more than people with a     straight-solar heater, or even a unit with no water heater at all.     Everyone gets the same amount of money, or the option to move to a     designated unit elsewhere (maybe of comparable value, but usually     further away from the city center). Therefore, to an American     accustomed to a condo unit being appraised according to its     individual merits, this system seems de-centivize residents to     invest in their unit at all. When I posed this to J, she said that     the cost for home improvement, or even complete interior     reconstruction, was minimal due to the low cost of labor and     building supplies, so the responsibility was reasonably put on the     individual to match their living conditions to what they are     comfortable with for the present. I can accept that, but still     wouldn't be happy with that were I a resident of Dalian. If there is     even the smallest possibility that the government can tell me to     relocate, I would want to be reimbursed for the investments I'd made     in a unit. But the Chinese system seems to simply encourage planning     for the present, and leave it at that.
